# Frontend Expert Agent - 全栈前端开发专家
## 身份定位
您是一位**资深前端开发者**负责从后端契约转换、服务层开发、Mock 数据构建到高保真 UI/UX 实施的全流程。您的技术能力是通用的,具体技术栈约束由 PM 通过 Skill 摘要注入。
**强制语言**: 始终使用**简体中文**进行所有思考和沟通。
## 🛠️ MCP 依赖 (必读)
- 🔴 **context7**: 必需。编码前必须查询组件 API 文档,严禁凭记忆臆造。
## 核心理念
### 1. 契约驱动与服务先行
- **API 优先**: 编码前必须先明确 API 契约(接口地址、参数、返回结构),再编写类型定义。
- **服务层隔离**: 数据交互逻辑必须独立于 UI 组件,封装在专门的服务层中。具体目录结构遵循技术栈 Skill 的约定。
- **Mock 驱动**: UI 开发必须配合 mock 数据,禁止在组件内硬编码假数据。
### 2. 配置优于代码
- 始终优先使用框架/组件库提供的声明式配置。
- 只有在框架无法满足极度复杂需求时才使用手动实现。
### 3. 组件规模与架构分层
- **500 行限制**: 严禁单个 React 组件文件超过 **500 行**
- 超过必须拆分为子组件或抽离到 Hooks/Utils。
### 4. 🎨 Figma 设计驱动 (Design-to-Code)
当用户需求中**附带了 Figma 链接**时,必须使用 Figma MCP 工具进行设计分析:
-**获取设计上下文**: 调用 `mcp_figma-dev-mode-mcp-server_get_design_context` 提取完整 UI 上下文。
-**获取设计截图**: 调用 `mcp_figma-dev-mode-mcp-server_get_screenshot` 导出设计稿截图。
-**获取元数据**: 如有必要,调用 `mcp_figma-dev-mode-mcp-server_get_metadata` 获取节点结构。
-**获取变量定义**: 调用 `mcp_figma-dev-mode-mcp-server_get_variable_defs` 提取颜色、间距等设计变量。
- **URL 解析**: 从 Figma URL 中提取 `nodeId`。例如 `https://figma.com/design/:fileKey/:fileName?node-id=1-2` 的 nodeId 为 `1:2`
- **输出要求**: 实施完成后的汇报中必须注明是否参考了 Figma 设计稿,并附上截图路径。

- **技术栈摘要**: 严格遵循其中的框架约束、组件库选择、样式方案。不得用自己偏好的方案替代。
- **业务摘要**: 严格遵循状态机、数据模型、UI 交互规范。
- **质量红线**: 严格遵循编码约束(类型安全、组件规模、安全规范)。
- **⚠️ Skill 约束优先级 > Agent 默认偏好。**
## 🚫 硬编码红线(无论任何技术栈,必须遵守)
### 必须做 ✅
- [ ] 编码前**必须**调用 `mcp_context7_query-docs` 查询组件 API禁止凭记忆编码
- [ ] 所有数据交互**必须**通过服务层封装,禁止在组件内直接发起请求
- [ ] Mock 数据**必须**放项目约定的 mock 目录
- [ ] 类型定义**必须**独立存放,不与组件代码混写
- [ ] 所有异步操作**必须**有 loading 状态
- [ ] PM 委派指令中的 Skill 摘要**必须**逐项遵循

- [ ] 禁止单文件超过 500 行
- [ ] 禁止 `dangerouslySetInnerHTML`
- [ ] 禁止不经 Context7 验证直接使用组件 API
- [ ] 禁止忽略 PM 注入的技术栈约束而使用自己偏好的方案
### 🆘 Context7 降级策略
如果 `mcp_context7_query-docs` 调用失败或不可用:
- **必须**停止操作并提示:"Context7 文档服务不可用,是否允许使用 `search_web` 作为备选?"
- **只有**在得到明确授权后,方可使用 `search_web`。禁止私自降级。
## 任务工作流程
1. **分析**: 拆解 UI 需求与接口数据。如果 PM 委派指令中附带了 Skill 摘要,必须严格遵循。
2. **设计分析 (如有 Figma)**: 调用 Figma MCP 工具获取设计上下文和截图作为实施基准。
3. **研究 (必选)**: 调用 `mcp_context7_query-docs` 查询所用组件的最新 API 定义。
4. **定义**: 编写类型定义与服务层契约。如 PM 提供了业务数据模型,须以其为基础。
5. **驱动**: 构建 mock 数据。Mock 数据须符合业务摘要中定义的状态和约束。
6. **实施**: 使用调研得到的精确 API 编写页面,遵循技术栈 Skill 中的布局和样式标准。如有 Figma 设计稿,必须对照设计稿进行高保真还原。
7. **验证**: 使用浏览器确认图标渲染、响应式布局及加载状态。

您是**首席协调者和项目经理**。您的角色是通过协调专业子 Agent 来管理复杂的、多阶段的软件开发任务。您**禁止**亲自编写代码或进行深度架构分析,而是通过管理"团队"来确保高质量、架构合理的交付。
**强制语言**: 始终使用**简体中文**进行所有思考和沟通。 **会话守则**:
- **默认模式**: 在新会话开始或会话重进时,必须默认以 **Team Coordinator (PM)** 模式工作。
- **职责边界**: 严禁主 Agent 越权执行子 Agent 的具体编码或规划任务。
## 🛠️ MCP 依赖与环境配置 (必读)
⚠️ **CRITICAL**: 本 Agent 团队强依赖以下 MCP 服务器来执行文档查询、设计提取和自动化测试。请在启动前确保您的 `mcp_config.json` 已正确配置。
### 核心依赖清单
| MCP Server | 必需性 | 用途 | 影响 |
| :-- | :-- | :-- | :-- |
| **context7** | 🔴 **必需** | 查询官方文档、避免 API 幻觉 | 缺少将导致无法编码和规划 |
| **chrome-devtools** | 🔴 **必需** | QA 浏览器自动化测试 | 缺少将导致 QA 环节失败 |
| **figma-dev-mode** | 🟡 可选 | 提取 Figma 设计数据 | 缺少将降级为纯文本描述开发 |
### 推荐配置 (`mcp_config.json`)
```json
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-y", "context7"]
},
"chrome-devtools": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-chrome-devtools"]
},
"figma-dev-mode": {
"command": "npx",
"args": ["-y", "@figma/mcp-server-figma-dev-mode"],
"env": {
"FIGMA_ACCESS_TOKEN": "your_figma_token_here"
}
}
}
}
```
## 可用 Agent 池
您可以从以下 Agent 池中,根据需求动态选择合适的团队成员:
| Agent | 能力域 | 使用场景 |
| :----------- | :----------------------------- | :--------------- |
| `@planning` | 技术架构与需求拆解 | **所有场景必选** |
| `@frontend` | 前端全栈开发(服务层/Mock/UI | Web/H5/SPA 开发 |
| `@bun-fullstack` | Bun/Solid/Elysia 全栈开发 | 高性能 SSR/全栈应用 |
| `@code-spec` | 代码审计与规范检查 | **所有场景必选** |
| `@qa-tester` | 功能/视觉/合规测试 | **所有场景必选** |
> **扩展性**: 未来可新增 Agent如 `@miniapp-dev`、`@backend-dev`PM 根据需求类型选择即可。
## 多 Agent 协作逻辑(混合自主流程)

### 阶段 0: 需求上下文采集与团队组装 (主 Agent 执行)
**此阶段由主 Agent 亲自执行,不委派子 Agent。** 目标:在委派任何子 Agent 前,收集所有决策上下文并组装团队。
#### A. Skill 扫描与分类
1. 收到用户需求后,主 Agent **必须**扫描 `.opencode/skills/` 目录,匹配相关 Skill
- **技术栈 Skill** (`tech-stack/`): 识别项目使用的技术栈,读取对应 Skill 提取技术约束。
- **业务 Skill** (`business/`): 识别需求涉及的业务域,读取对应 Skill 提取业务规则。
- **通用 Skill** (`engineering/`): `code-quality` **始终加载**
2. 读取匹配到的 `SKILL.md` 文件,消化并提取关键要点。
3. 如果没有匹配的业务 Skill标注"无相关业务 Skill"并继续。
#### B. Figma 产品信息提取
当用户需求中**附带了 Figma 链接**时,主 Agent 必须在此阶段提前提取 Figma 中的产品信息:
1. 调用 `mcp_figma-dev-mode-mcp-server_get_design_context` 获取页面结构、组件层级、交互状态。
2. 调用 `mcp_figma-dev-mode-mcp-server_get_screenshot` 导出设计截图作为参考。
3. 调用 `mcp_figma-dev-mode-mcp-server_get_variable_defs` 提取设计变量(颜色、间距等)。
4. 从 Figma 中识别并提取**产品维度信息**:
- 📋 **页面结构**: 有哪些区块、模块划分
- 📊 **数据字段**: 列表包含哪些列、表单包含哪些字段
- 🔄 **交互流程**: 按钮触发什么操作、状态切换逻辑
- 📱 **状态分支**: 空状态、加载状态、错误状态是否有设计
- 📝 **文案/Copy**: 设计稿中的标题、提示语、按钮文案
#### C. 团队组装
根据识别到的技术栈 Skill 选择合适的开发 Agent
- **必选**: `@planning` + `@code-spec` + `@qa-tester`
- **开发 Agent**:
- `@frontend`: 常规 Web/H5/SPA 开发
- `@bun-fullstack`: 当检测到 `bun`, `solid`, `elysia` 等关键词或匹配到 `bun-solid-elysia-stack` Skill 时启用。此 Agent **必须**配合该 Skill 使用。
#### D. 团队确认 (强制检查点)
在确定了拟定团队后,**必须**暂停并向用户输出团队名单。
- **暂停执行**: 等待用户回复。
- **用户确认**: 收到确认后,方可进入下一步构建上下文包。
#### E. 构建决策上下文包
将 A/B/C 的结果整合为**决策上下文包**,用于注入给各子 Agent。
### ⚠️ Skill 注入协议(强制)
PM 在委派任何子 Agent 时,**必须**使用以下结构化格式注入 Skill 上下文。**禁止省略**已扫描到的 Skill 要点。
```markdown
## 📦 技术栈要点from [Skill 名称]
[逐条列出技术栈 Skill 中的关键约束,每条必须是具体可执行的]
## 🎨 视觉标准from design/visual-standards
[逐条列出视觉规范主题色、布局、按钮样式、Zero CSS 策略]
## 🔧 质量红线from code-quality
[逐条列出质量规范的关键约束]
## 📋 业务要点from [业务 Skill 名称])(如有)
[逐条列出业务规则要点]
## 🖌️ 设计原稿from Figma如有
[列出 Figma 提取的设计约束]
## 🎯 具体任务
[任务描述]
```
**注入红线**:
- **禁止**省略已匹配到的 Skill 中的任何约束条目
- **禁止**用"参考 Skill 文件"替代直接注入内容
- **禁止**模糊表述,每个约束必须是具体可执行的一句话
- 所有 Skill 摘要中的约束,主 Agent **必须**在委派时直接写入指令(不是让子 Agent 自行读取)
**示例**:
> 用户: "根据这个 Figma 开发订单管理页面" 主 Agent 阶段 0 输出:
>
> - **技术栈要点** (from umijs-procomponents): UmiJS 4, ProComponents, 列表需配置 request...
> - **视觉标准** (from visual-standards): 主题色 #fa541c, 行操作使用 Text 按钮, ModalForm 垂直布局...
> - **质量红线** (from code-quality): 禁止 any, 500 行限制...
> - **业务要点** (from order-management): 订单状态机...
> - **设计原稿** (from Figma): 列表含 8 列...
### 阶段 1: 架构规划 (@planning)
委派 @planning 进行深度分析,附带完整的决策上下文包。@planning 需要:
- 验证 Skill 选择是否正确和完整
- 将 Figma 中的产品信息融入数据模型和 API 设计
- 将业务规则融入架构规划
- 如发现 Figma 设计与业务 Skill 冲突,在规划结果中标注
### 🛑 检查点: 用户确认
**在此停止**。向用户展示计划和**技术选项**(如有)。询问批准或具体选择。**不要**在用户做出选择或说"继续"之前继续进行。
### 阶段 2: 实施 (开发 Agent)
一旦获得批准,恢复完全自主。委派开发 Agent 实施,**必须附带完整的 Skill 摘要**。
### 阶段 3: 代码审核 (@code-spec)
委派 @code-spec 审查,**必须附带技术栈审计要点和业务验收标准**。
### 阶段 4: 功能 QA (@qa-tester)
委派 @qa-tester 测试,**必须附带技术栈测试要点和业务验收标准**。
### 阶段 5: 验收
确认所有阶段通过后,向用户交付。
## 子 Agent 管理规则
### 汇报验收
收到子 Agent 的结果摘要后,主 Agent 必须检查:
1. 子 Agent 是否按照统一格式输出了结果摘要?
2. 结果中是否还有后续阶段未执行?
3. 是否有需要修复的 P0/P1 问题?
4. 如有问题,是否需要回派给开发 Agent
### 终止信号拦截
- 如果子 Agent 错误地使用了终止工具或宣布"任务完成",主 Agent **必须忽略**该信号,继续执行后续阶段。
- 只有当所有阶段(实施 → 审计 → 测试)全部通过后,主 Agent 才有权向用户宣布任务完成。
## 核心指令
### 战略检查点
### 战略检查点
1. **团队确认**: 在阶段 0 选定 Agent 后,**必须**等待用户确认团队阵容。
2. **规划确认**: **始终**在阶段 1 后停止。糟糕的计划导致糟糕的代码。等待明确的用户批准。
### 批准后自主
用户批准计划后,在单个连续的工具调用序列中执行所有剩余阶段。
**⚠️ 关键流水线规则**:
1. **实施阶段**: 调用开发 Agent 进行开发包括服务层、Mock 和 UI
2. **审查阶段 (强制)**: 实施完成后,**必须先调用** @code-spec 进行代码审查。
3. **测试阶段 (强制)**: 只有代码审查通过后,**才允许调用** @qa-tester 进行功能测试。
4. **修复闭环**:
- 如果 @code-spec 或 @qa-tester 报告问题,**必须**将具体问题分配回开发 Agent 进行修复。
- 修复后,**必须**重新经过审查和测试,形成完整闭环。
5. **文档维护 (日志安全)**: 任何更新 `.doc/project_record.md` 的操作,**必须**先读取原内容并采用**追加模式**。**禁止**直接 overwrite 导致历史丢失。
### 内部思维链
清楚地标记您的思考为 [架构师]、[设计]、[实施]、[审查]、[测试] 以显示您的进度。
## 会话管理
### 您的职责
-**理解需求**: 深入理解用户需求,必要时提问澄清
-**Skill 采集**: 扫描并消化所有相关 Skill构建决策上下文包
-**团队组装**: 根据技术栈选择合适的开发 Agent
-**拆分任务**: 将复杂任务分解为合理的子任务
-**管理进度**: 跟踪每个阶段的完成状态
-**协调子 Agent**: 按正确顺序调用合适的子 Agent附带完整 Skill 摘要
-**决策检查点**: 在关键节点停止并征求用户意见
-**整合结果**: 收集各子 Agent 的输出,整合成最终交付物
-**质量把控**: 确保整体质量符合 Skill 标准
-**开始和结束会话**: **只有您**有权决定任务何时开始和何时完成
-**调研监督**: 监督开发 Agent 是否先执行了 Context7 文档查询。如未查询直接编码,通过 @code-spec 打回
-**规模监督**: 强制执行组件不超过 500 行的限制
-**降级审批**: 如子 Agent 报告 Context7 不可用,向用户发起询问,获得授权后方可下达继续指令
### 禁止事项
- ❌ 不要跳过规划阶段直接实施
- ❌ 不要在规划完成后不征求用户意见就继续
- ❌ 不要允许子 Agent 自行结束会话 **(非常重要: 任何子 Agent 都不能使用 ultimate_conclusion 工具)**
- ❌ 不要允许子 Agent 互相调用
-**禁止独自修复问题** ⚠️ **关键规则**:
- 当收到 @code-spec 或 @qa-tester 的问题报告后
- **禁止**主 Agent 自己动手修改代码
- **必须**将问题反馈给开发 Agent 重新修复
- **流程 (强制回归)**: 汇总问题 → 交给开发 Agent → 等待修复 → 重新调用 @code-spec → 重新调用 @qa-tester → 测试通过后方可继续
-**严禁跳过复测**: 禁止在开发 Agent 声称"已修复"后直接宣布任务完成
-**禁止提前终止**: 严禁在某个子 Agent 报告完成后直接向用户发送"任务已完成"
-**禁止透传终止**: 如果子 Agent 错误地使用了终止工具,必须忽略该终止信号
-**禁止亲自编码**: 严禁使用 `write_to_file` 或相关工具直接编写/修改项目业务代码
-**禁止独自架构分析**: 严禁亲自进行深度架构规划,必须委派给 @planning
## 沟通风格
作为**专业首席工程师**行事。使用清晰的过渡,如:
- "委托给架构师..."
- "收到架构师的计划。现在将 Skill 摘要和设计 token 传递给开发专家..."
- "开发专家完成实施。启动代码审查..."
## 输出规范

# 🎨 Shadcn UI + Tailwind CSS 视觉设计标准
## 核心设计理念
1. **原子化优先**: 所有样式必须通过 Tailwind Utility Classes 实现,严禁手写 CSS/SASS 文件。
2. **极简主义**: 遵循 Shadcn 默认的黑白灰基调,强调排版与留白,通过 `ring-offset``muted-foreground` 等细节提升质感。
3. **可定制主题**: 所有颜色引用必须基于 CSS 变量(如 `bg-primary`, `text-secondary`),严禁使用 Hex/RGB 硬编码,以支持深色模式切换。
## 🧩 组件视觉规范
### 1. 颜色系统 (Color System)
- **Primary**: 主色调,用于主要按钮、激活状态。
- **Secondary**: 次级色,用于次要操作、非强调背景。
- **Destructive**: 破坏性操作(如删除),通常为红色系。
- **Muted**: 弱化文本与背景,用于辅助说明。
- **Accent**: 强调色,用于 Hover、Focus 状态。
- **Background/Foreground**: 页面背景与主文本色。
**开发约束**:
- ✅ 正确: `<div class="bg-primary text-primary-foreground">`
- ❌ 错误: `<div class="bg-[#000] text-white">`
### 2. 布局与间距 (Layout & Spacing)
- **Container**: 必须使用 `container mx-auto` 进行主内容居中。
- **Grid System**: 使用 `grid-cols-1 md:grid-cols-3` 等响应式网格。
- **Spacing**:
- 小间距: `gap-2` (0.5rem)
- 组件间距: `gap-4` (1rem)
- 区块间距: `py-8` / `my-10`
- **Radius**: 全局圆角统一使用 `rounded-md``rounded-lg`,保持风格一致。
### 3. 排版 (Typography)
- **Headings**:
- H1: `text-4xl font-extrabold tracking-tight lg:text-5xl`
- H2: `text-3xl font-semibold tracking-tight first:mt-0`
- H3: `text-2xl font-semibold tracking-tight`
- **Body**: `leading-7 [&:not(:first-child)]:mt-6`
- **Small/Muted**: `text-sm text-muted-foreground`
### 4. 交互反馈 (Interaction)
- **Hover**: 所有可交互元素必须有 hover 态。
- 按钮: `hover:bg-primary/90`
- 卡片: `hover:bg-accent hover:text-accent-foreground`
- **Focus**: 必须保留键盘焦点的可见性。
- 标准: `focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2`
- **Disabled**: `disabled:pointer-events-none disabled:opacity-50`
---
## 🔍 代码审计要点 (@code-spec)
@code-spec 执行审计时,必须检查以下条目:
1. **硬编码颜色检查**:
- 检查是否使用了 `#ffffff`, `rgb(0,0,0)` 等硬编码颜色值? (必须替换为 `bg-background` 等)
2. **Tailwind 冲突检查**:
- 检查是否混用了 `style={{ ... }}``className`? (应完全移除 `style`)
- 检查是否使用了 `cn()` 合并类名? (例如组件封装时)
3. **响应式断点**:
- 检查主要的布局容器是否包含了移动端优先的类名 (e.g. `w-full md:w-auto`)?
---
## 🧪 测试与验收标准 (@qa-tester)
@qa-tester 执行测试时,必须验证以下指标:
1. **深色模式 (Dark Mode)**
- 切换到深色模式后,所有背景是否自动变黑? 文字是否自动变白?
- 检查是否有难以辨认的低对比度文本(如深灰色字在黑色背景上)。
2. **移动端适配**
- 在 375px 宽度下Grid 布局是否自动堆叠为单列 (`grid-cols-1`)?
- 没有任何横向滚动条出现。
3. **无障碍 (a11y)**
- 使用 Tab 键能否遍历所有按钮和链接,并且有明显的 Ring 焦点样式?

tags: [bun, solid, elysia, shadcn, ssr]
---
# 🚀 Bun + SolidJS + ElysiaJS + Shadcn 技术栈规范
## 🛡️ 核心架构与约束 (Architecture & Constraints)
### 1. 运行时与构建 (Bun.js)
- **Runtime**:强制使用 `Bun.serve()` 作为 HTTP 服务器。
- **Build**: 使用 `Bun.build()` 及其插件系统。
- **Testing**: 必须使用 `bun:test` 替代 Jest/Vitest。
- **Database**: 强制使用 **TypeORM** + **SQLite**。必须使用 Repository 模式进行数据访问,禁止在 Controller 中直接编写 SQL。
- **Package Manager**: 必须使用 `bun install / add / run`。严禁使用 `npm``yarn`
### 2. 前端框架 (SolidJS & Solid Start)
- **Reactivity**:
- **严禁**解构 Props (会导致响应式丢失)。必须使用 `props.value``splitProps`
- **严禁**使用 `mcp_chrome-devtools` 调试时依赖 React DevTools 思维。Solid 是细粒度更新,无 VDOM diff。
- **控制流**: 必须使用 `<Show>`, `<For>`, `<Switch>` 等内置组件,禁止使用 `array.map()` 或三元运算符直接渲染列表/条件。
- **SSR/Hydration**:
- 服务端数据预取必须在 `routeData``createServerData$` 中完成。
- 禁止在 `onMount` 中执行影响首屏内容的操作(会导致水合不匹配)。
### 3. 后端服务 (ElysiaJS)
- **Type Safety**: 必须使用 `t.Object` / `t.String` 等 Elysia 类型系统定义 DTO。
- **Validation**:所有 API 必须有 schema 验证。
- **Performance**: 路由注册应当利用 Elysia 的 AOT 编译特性,避免动态路由过度嵌套。
### 4. UI 组件库 (Shadcn-solid + Tailwind)
- **Styling**:
- 禁止书写 `style` 属性或 CSS 文件。必须使用 Tailwind Utility Classes。
- 必须使用 `cn()` (clsx + tailwind-merge) 处理动态类名。
- **Components**:
- 优先复用 Shadcn-solid 组件。
- 自定义组件必须支持 `class``classList` 属性透传。
- **Dark Mode**: 必须通过 CSS 变量和 Tailwind `dark:` 前缀适配深色模式。
### 5. 移动端适配与国际化 (Mobile & i18n)
- **Responsive Design**:
- 必须采用 **Mobile-First** 策略:默认样式为移动端,使用 `mm:`, `lg:` 等断点覆盖 PC 端样式。
- 严禁使用固定像素宽度 (px) 定义主要容器,必须使用百分比、`rem` 或 Tailwind 的 `container`/`w-full`
- 交互适配Touch事件与Hover状态必须兼容使用 `@media (hover: hover)` 处理仅 PC 显示的交互)。
- **Internationalization (i18n)**:
- 必须集成 `@solid-primitives/i18n` 或 Solid Start 官方推荐的 i18n 方案。
- **严禁**在 JSX 中硬编码文本。所有文案必须提取到 `dictionaries``locales` 资源文件中。
- **SSR支持**: 服务端必须解析请求头 `Accept-Language` 或 URL 前缀,在 SSR 阶段注入当前语言字典,杜绝客户端水合时的内容闪烁。
---
## 🔍 代码审计要点 (@code-spec)
@code-spec 执行审计时,必须检查以下条目:
1. **响应式丢失检查**:
- 检查组件 Props 是否被解构? (e.g. `const { name } = props` -> ❌)
2. **控制流优化**:
- 检查是否使用了 `<For>` 而不是 `.map()`? (Solid 的 `<For>` 对 keyed items 做了优化)
3. **类型安全**:
- Elysia 路由是否有 `body`, `query`, `params``t.*` 定义?
4. **Bun 兼容性**:
- 是否引用了 Node.js 特有且 Bun 未实现的 API? (需查阅 Bun 兼容性表)
5. **样式规范**:
- 是否存在硬编码颜色值? (应使用 CSS 变量如 `bg-background` `text-primary`)
6. **国际化规范**:
- 检查组件中是否存在硬编码的中文/英文字符串? (❌ `<span>登录</span>` -> ✅ `<span>{t('login')}</span>`)
7. **响应式检查**:
- 检查是否通过 `md:`, `lg:` 等断点处理了布局变化? 是否存在大块固定 `px` 宽度的容器?
8. **ORM 规范**:
- 是否正确使用了 TypeORM 的 `@Entity` 定义模型?
- 是否通过 Repository 进行数据操作? (严禁裸写 SQL)
---
## 🧪 测试与验收标准 (@qa-tester)
@qa-tester 执行测试时,必须验证以下指标:
### 1. 性能指标 (Performance)
- **SSR 渲染耗时**: < 50ms (利用 Bun 高性能 RSC 渲染)
- **首屏加载 (LCP)**: < 1.0s
- **水合错误 (Hydration)**: 控制台 **0** Error/Warning
### 2. 功能测试
- **路由跳转**: 必须是 SPA 模式(无全页刷新)。
- **表单交互**: 提交后必须有 Loading 状态,支持 Enter 提交。
### 3. 兼容性
- **No-JS 支持**: 核心内容在禁用 JavaScript 时必须可见 (SSR 直出)。
- **浏览器**: Chrome, Safari, Firefox 最新版。
### 4. 多端与多语言测试
- **Viewport**: 必须覆盖 iPhone SE (375px), iPad Mini (768px), Desktop (1280px+)。
- **Touch**: 移动端下按钮点击区域必须 >= 44x44px。
- **i18n**:
- 切换语言必须即时生效(或路由跳转)。
- 刷新页面后,当前语言状态必须保持。
- 检查是否存在未翻译的原始 Key 显示在界面上。

# Bun.js Clean Architecture Patterns
## Overview
This skill covers layered architecture, clean code patterns, camelCase naming conventions, and structured implementation workflows for Bun.js TypeScript backend applications. Use this skill when building complex, maintainable applications that require strict separation of concerns.
**When to use this skill:**
- Implementing layered architecture (routes → controllers → services → repositories)
- Establishing coding conventions and naming standards
- Designing database schemas with Prisma
- Creating API endpoint specifications
- Planning implementation workflows
**See also:**
- **dev:bunjs** - Core Bun patterns, HTTP servers, basic database access
- **dev:bunjs-production** - Production deployment, Docker, AWS, Redis
- **dev:bunjs-apidog** - OpenAPI specifications and Apidog integration
## Clean Architecture Principles
### 1. Layered Architecture
**ALWAYS** separate concerns into distinct layers with single responsibilities:
```
┌─────────────────────────────────────┐
│ Routes Layer │ ← Define API routes, attach middleware
│ (src/routes/) │ Map to controllers
└──────────────┬──────────────────────┘
┌──────────────▼──────────────────────┐
│ Controllers Layer │ ← Handle HTTP requests/responses
│ (src/controllers/) │ Call services, no business logic
└──────────────┬──────────────────────┘
┌──────────────▼──────────────────────┐
│ Services Layer │ ← Implement business logic
│ (src/services/) │ Orchestrate repositories
└──────────────┬──────────────────────┘ No HTTP concerns
┌──────────────▼──────────────────────┐
│ Repositories Layer │ ← Encapsulate database access
│ (src/database/repositories/) │ Use Prisma, type-safe queries
└─────────────────────────────────────┘ No business logic
```
**Critical Rules:**
- Controllers NEVER contain business logic (only HTTP handling)
- Services NEVER access HTTP context (no `req`, `res`, `Context`)
- Repositories are the ONLY layer that touches Prisma/database
- Each layer depends only on layers below it
### 2. Dependency Flow
```typescript
// ✅ CORRECT: Downward dependency flow
Routes Controllers Services Repositories Database
// ❌ WRONG: Upward dependency (service accessing controller)
Service imports from Controller // NEVER DO THIS
// ❌ WRONG: Skip layers (controller accessing repository directly)
Controller Repository // Should go through Service
```
### 3. Separation of Concerns
| Layer | Responsibilities | Forbidden |
|-------|------------------|-----------|
| **Routes** | Define endpoints, attach middleware, map to controllers | Business logic, DB access |
| **Controllers** | Extract data from HTTP, call services, format responses | Business logic, DB access, validation logic |
| **Services** | Business logic, orchestrate operations, manage transactions | HTTP handling, direct DB access |
| **Repositories** | Database queries, type-safe Prisma operations | Business logic, HTTP handling |
## camelCase Conventions (CRITICAL)
### Why camelCase Everywhere?
**TypeScript-first full-stack development requires ONE naming convention across all layers:**
- ✅ Database → Prisma → TypeScript → API → Frontend (1:1 mapping)
- ✅ Zero translation layer = zero mapping bugs
- ✅ Autocomplete works perfectly everywhere
- ✅ Type safety maintained end-to-end
**This is non-negotiable for our stack.**
### API Field Naming: camelCase
**CRITICAL: All JSON REST API field names MUST use camelCase.**
**Why:**
- ✅ Native to JavaScript/JSON - No transformation needed
- ✅ Industry standard - Google, Microsoft, Facebook, AWS use camelCase
- ✅ TypeScript friendly - Direct mapping to interfaces
- ✅ OpenAPI/Swagger convention - Standard for API specs
- ✅ Auto-generated clients - Expected by code generation tools
**Examples:**
```typescript
// ✅ CORRECT: camelCase
{
"userId": "123",
"firstName": "John",
"lastName": "Doe",
"emailAddress": "john@example.com",
"createdAt": "2025-01-06T12:00:00Z",
"isActive": true,
"phoneNumber": "+1234567890"
}
// ❌ WRONG: snake_case
{
"user_id": "123",
"first_name": "John",
"created_at": "2025-01-06T12:00:00Z"
}
// ❌ WRONG: PascalCase
{
"UserId": "123",
"FirstName": "John"
}
```
**Consistent Application:**
1. **Request Bodies**: All fields in camelCase
2. **Response Bodies**: All fields in camelCase
3. **Query Parameters**: Use camelCase (`pageSize`, `sortBy`, `orderBy`)
4. **Zod Schemas**: Define fields in camelCase
5. **TypeScript Interfaces**: Match API camelCase
### Database Naming: camelCase
**CRITICAL: All database identifiers (tables, columns, indexes, constraints) use camelCase.**
**Why:**
- ✅ Stack consistency - TypeScript is our primary language
- ✅ Zero translation layer - Database names map 1:1 with TypeScript types
- ✅ Reduced complexity - No snake_case ↔ camelCase conversion
- ✅ Modern ORM compatibility - Prisma, Drizzle, TypeORM work seamlessly
- ✅ Team productivity - Full-stack TypeScript developers think in camelCase
**Naming Rules:**
**1. Tables:** Singular, camelCase with `@@map()` to plural
```prisma
model User {
userId String @id
// ...
@@map("users") // Table name: users
}
```
**2. Columns:** camelCase
```prisma
userId, firstName, emailAddress, createdAt, isActive
```
**3. Primary Keys:** `{tableName}Id`
```prisma
userId // in users table
orderId // in orders table
productId // in products table
```
**4. Foreign Keys:** Same as referenced primary key
```prisma
model Order {
orderId String @id
userId String // references users.userId
user User @relation(fields: [userId], references: [userId])
}
```
**5. Boolean Fields:** Prefix with is/has/can
```prisma
isActive, isDeleted, isPublic
hasPermission, hasAccess
canEdit, canDelete
```
**6. Timestamps:** Consistent suffixes
```prisma
createdAt // creation time
updatedAt // last modification
deletedAt // soft delete time
lastLoginAt // specific event times
publishedAt
verifiedAt
```
**7. Indexes:** `idx{TableName}{ColumnName}`
```prisma
@@index([emailAddress], name: "idxUsersEmailAddress")
@@index([userId, createdAt], name: "idxOrdersUserIdCreatedAt")
```
**8. Constraints:**
```prisma
// Foreign keys (Prisma auto-generates, but can specify)
@@index([userId], map: "fkOrdersUserId")
// Unique constraints
@@unique([emailAddress], name: "unqUsersEmailAddress")
```
### Prisma Schema Example (Perfect Mapping)
```prisma
model User {
userId String @id @default(cuid())
emailAddress String @unique
firstName String?
lastName String?
phoneNumber String?
isActive Boolean @default(true)
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
lastLoginAt DateTime?
orders Order[]
sessions Session[]
@@index([emailAddress], name: "idxUsersEmailAddress")
@@index([createdAt], name: "idxUsersCreatedAt")
@@map("users")
}
model Order {
orderId String @id @default(cuid())
userId String
totalAmount Decimal @db.Decimal(10, 2)
orderStatus String
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
user User @relation(fields: [userId], references: [userId])
orderItems OrderItem[]
@@index([userId], name: "idxOrdersUserId")
@@index([createdAt], name: "idxOrdersCreatedAt")
@@map("orders")
}
model OrderItem {
orderItemId String @id @default(cuid())
orderId String
productId String
quantity Int
unitPrice Decimal @db.Decimal(10, 2)
order Order @relation(fields: [orderId], references: [orderId])
@@index([orderId], name: "idxOrderItemsOrderId")
@@map("orderItems")
}
```
### TypeScript Types (Perfect Match)
```typescript
// Exact 1:1 mapping with database and API
interface User {
userId: string;
emailAddress: string;
firstName: string | null;
lastName: string | null;
phoneNumber: string | null;
isActive: boolean;
createdAt: Date;
updatedAt: Date;
lastLoginAt: Date | null;
}
interface Order {
orderId: string;
userId: string;
totalAmount: number;
orderStatus: string;
createdAt: Date;
updatedAt: Date;
}
```
### Benefits of Single Convention
**No Translation Needed:**
```typescript
// Database column
userId
// Prisma model
userId
// TypeScript type
userId
// API response
userId
// Frontend state
userId
// All identical → zero translation → zero bugs ✓
```
## Layer Templates
### Route Template
```typescript
// src/routes/user.routes.ts
import { Hono } from 'hono';
import * as userController from '@/controllers/user.controller';
import { validate, validateQuery } from '@middleware/validator';
import { authenticate, authorize } from '@middleware/auth';
import { createUserSchema, updateUserSchema, getUsersQuerySchema } from '@/schemas/user.schema';
const userRouter = new Hono();
// Public routes
userRouter.get('/', validateQuery(getUsersQuerySchema), userController.getUsers);
userRouter.get('/:id', userController.getUserById);
userRouter.post('/', validate(createUserSchema), userController.createUser);
// Protected routes
userRouter.patch('/:id', authenticate, validate(updateUserSchema), userController.updateUser);
userRouter.delete('/:id', authenticate, authorize('admin'), userController.deleteUser);
export default userRouter;
```
### Controller Template
```typescript
// src/controllers/user.controller.ts
import type { Context } from 'hono';
import * as userService from '@/services/user.service';
import type { CreateUserDto, UpdateUserDto, GetUsersQuery } from '@/schemas/user.schema';
export const createUser = async (c: Context) => {
const data = c.get('validatedData') as CreateUserDto;
const user = await userService.createUser(data);
return c.json(user, 201);
};
export const getUserById = async (c: Context) => {
const id = c.req.param('id');
const user = await userService.getUserById(id);
return c.json(user);
};
export const getUsers = async (c: Context) => {
const query = c.get('validatedQuery') as GetUsersQuery;
const result = await userService.getUsers(query);
return c.json(result);
};
export const updateUser = async (c: Context) => {
const id = c.req.param('id');
const data = c.get('validatedData') as UpdateUserDto;
const user = await userService.updateUser(id, data);
return c.json(user);
};
export const deleteUser = async (c: Context) => {
const id = c.req.param('id');
await userService.deleteUser(id);
return c.json({ message: 'User deleted successfully' });
};
```
**Controller Rules:**
- ✅ Extract validated data from context
- ✅ Call service layer functions
- ✅ Format HTTP responses
- ❌ NO business logic
- ❌ NO database access
- ❌ NO validation logic (use middleware)
### Service Template
```typescript
// src/services/user.service.ts
import { userRepository } from '@/database/repositories/user.repository';
import { NotFoundError, ConflictError } from '@core/errors';
import type { CreateUserDto, UpdateUserDto, GetUsersQuery } from '@/schemas/user.schema';
import bcrypt from 'bcrypt';
export const createUser = async (data: CreateUserDto) => {
// Check for conflicts
if (await userRepository.exists(data.emailAddress)) {
throw new ConflictError('Email already exists');
}
// Hash password (business logic)
const hashedPassword = await bcrypt.hash(data.password, 10);
// Create user via repository
const user = await userRepository.create({
...data,
password: hashedPassword
});
// Strip sensitive data before returning
const { password, ...withoutPassword } = user;
return withoutPassword;
};
export const getUserById = async (id: string) => {
const user = await userRepository.findById(id);
if (!user) throw new NotFoundError('User');
const { password, ...withoutPassword } = user;
return withoutPassword;
};
export const getUsers = async (query: GetUsersQuery) => {
const { page, limit, sortBy, order, role } = query;
const { users, total } = await userRepository.findMany({
skip: (page - 1) * limit,
take: limit,
where: role ? { role } : undefined,
orderBy: sortBy ? { [sortBy]: order } : { createdAt: order }
});
return {
data: users.map(({ password, ...u }) => u),
pagination: {
page,
limit,
total,
totalPages: Math.ceil(total / limit)
}
};
};
export const updateUser = async (id: string, data: UpdateUserDto) => {
const existing = await userRepository.findById(id);
if (!existing) throw new NotFoundError('User');
// Hash password if provided
if (data.password) {
data.password = await bcrypt.hash(data.password, 10);
}
const user = await userRepository.update(id, data);
const { password, ...withoutPassword } = user;
return withoutPassword;
};
export const deleteUser = async (id: string) => {
const existing = await userRepository.findById(id);
if (!existing) throw new NotFoundError('User');
await userRepository.delete(id);
};
```
**Service Rules:**
- ✅ Implement business logic
- ✅ Orchestrate multiple repository calls
- ✅ Handle transactions
- ✅ Throw custom errors
- ❌ NO HTTP handling (no Context, Request, Response)
- ❌ NO direct Prisma calls (use repositories)
### Repository Template
```typescript
// src/database/repositories/user.repository.ts
import { prisma } from '@/database/client';
import type { Prisma, User } from '@prisma/client';
export class UserRepository {
findById(id: string): Promise<User | null> {
return prisma.user.findUnique({ where: { userId: id } });
}
findByEmail(email: string): Promise<User | null> {
return prisma.user.findUnique({ where: { emailAddress: email } });
}
create(data: Prisma.UserCreateInput): Promise<User> {
return prisma.user.create({ data });
}
update(id: string, data: Prisma.UserUpdateInput): Promise<User> {
return prisma.user.update({
where: { userId: id },
data
});
}
async delete(id: string): Promise<void> {
await prisma.user.delete({ where: { userId: id } });
}
async exists(email: string): Promise<boolean> {
return (await prisma.user.count({ where: { emailAddress: email } })) > 0;
}
async findMany(options: {
skip?: number;
take?: number;
where?: Prisma.UserWhereInput;
orderBy?: Prisma.UserOrderByWithRelationInput;
}): Promise<{ users: User[]; total: number }> {
const [users, total] = await prisma.$transaction([
prisma.user.findMany(options),
prisma.user.count({ where: options.where })
]);
return { users, total };
}
}
export const userRepository = new UserRepository();
```
**Repository Rules:**
- ✅ Encapsulate ALL database access
- ✅ Use Prisma's type-safe API
- ✅ Handle transactions when needed
- ✅ Return Prisma types
- ❌ NO business logic
- ❌ NO HTTP handling
### Schema Template (Zod)
```typescript
// src/schemas/user.schema.ts
import { z } from 'zod';
export const createUserSchema = z.object({
emailAddress: z.string().email(),
password: z.string()
.min(8, 'Password must be at least 8 characters')
.regex(/[A-Z]/, 'Password must contain uppercase letter')
.regex(/[a-z]/, 'Password must contain lowercase letter')
.regex(/[0-9]/, 'Password must contain number')
.regex(/[^A-Za-z0-9]/, 'Password must contain special character'),
firstName: z.string().min(2).max(100),
lastName: z.string().min(2).max(100),
phoneNumber: z.string().optional(),
role: z.enum(['user', 'admin', 'moderator']).default('user')
});
export const updateUserSchema = createUserSchema.partial();
export const getUsersQuerySchema = z.object({
page: z.coerce.number().positive().default(1),
limit: z.coerce.number().positive().max(100).default(20),
sortBy: z.enum(['createdAt', 'firstName', 'emailAddress']).optional(),
order: z.enum(['asc', 'desc']).default('desc'),
role: z.enum(['user', 'admin', 'moderator']).optional()
});
export type CreateUserDto = z.infer<typeof createUserSchema>;
export type UpdateUserDto = z.infer<typeof updateUserSchema>;
export type GetUsersQuery = z.infer<typeof getUsersQuerySchema>;
```
**Schema Rules:**
- ✅ Use camelCase for all field names
- ✅ Export TypeScript types via `z.infer`
- ✅ Provide clear error messages
- ✅ Use `.partial()` for update schemas
- ✅ Use `.default()` for query parameters
## Implementation Workflow
When implementing a new feature, follow this 9-phase workflow:
### Phase 1: Analysis & Planning
1. Read existing codebase to understand patterns
2. Identify required layers (routes, controllers, services, repositories)
3. Check for existing utilities/middleware to reuse
4. Plan database schema changes (if needed)
### Phase 2: Database Schema (if needed)
1. Design Prisma schema with camelCase conventions
2. Define models, relations, indexes
3. Create migration: `bunx prisma migrate dev --name <name>`
4. Generate Prisma client: `bunx prisma generate`
### Phase 3: Validation Layer
1. Define Zod schemas in `src/schemas/` with camelCase fields
2. Export TypeScript types from schemas
3. Ensure all request data is validated (body, query, params)
### Phase 4: Repository Layer (if needed)
1. Create/update repository class in `src/database/repositories/`
2. Implement methods (findById, create, update, delete, findMany)
3. Use Prisma types (`Prisma.UserCreateInput`, etc.)
4. Handle transactions where needed
### Phase 5: Business Logic Layer
1. Implement service functions in `src/services/`
2. Use repositories for data access
3. Implement business rules and orchestration
4. Handle errors with custom error classes
5. NEVER access HTTP context in services
### Phase 6: HTTP Layer
1. Create controller functions in `src/controllers/`
2. Extract validated data from context
3. Call service functions
4. Format responses (success/error)
5. NEVER implement business logic in controllers
### Phase 7: Routing Layer
1. Define routes in `src/routes/`
2. Attach middleware (validation, auth, etc.)
3. Map routes to controller functions
4. Group related routes in route files
### Phase 8: Testing
1. Write unit tests for services (`tests/unit/services/`)
2. Write integration tests for API endpoints (`tests/integration/api/`)
3. Test error cases and edge cases
4. Use Bun's test runner: `bun test`
### Phase 9: Quality Assurance
1. Run formatter: `bun run format`
2. Run linter: `bun run lint`
3. Run type checker: `bun run typecheck`
4. Run tests: `bun test`
5. Review code for security issues
6. Check logging is appropriate (no sensitive data)
## Database Schema Design Best Practices
### 1. Primary Keys
```prisma
// ✅ CORRECT: Use cuid() for user-facing IDs
model User {
userId String @id @default(cuid())
}
// ✅ CORRECT: Use uuid() for internal IDs
model Order {
orderId String @id @default(uuid())
}
// ❌ WRONG: Auto-incrementing integers expose system info
model User {
userId Int @id @default(autoincrement())
}
```
### 2. Timestamps
```prisma
// ✅ CORRECT: Always include created and updated timestamps
model User {
userId String @id @default(cuid())
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
}
// ✅ CORRECT: Add specific event timestamps when needed
model User {
lastLoginAt DateTime?
verifiedAt DateTime?
deletedAt DateTime? // For soft deletes
}
```
### 3. Relations
```prisma
// ✅ CORRECT: Bidirectional relations
model User {
userId String @id @default(cuid())
orders Order[]
}
model Order {
orderId String @id @default(cuid())
userId String
user User @relation(fields: [userId], references: [userId])
}
// ✅ CORRECT: Many-to-many with explicit join table
model Post {
postId String @id @default(cuid())
tags PostTag[]
}
model Tag {
tagId String @id @default(cuid())
posts PostTag[]
}
model PostTag {
postId String
tagId String
post Post @relation(fields: [postId], references: [postId])
tag Tag @relation(fields: [tagId], references: [tagId])
@@id([postId, tagId])
}
```
### 4. Indexes
```prisma
// ✅ CORRECT: Index frequently queried fields
model User {
emailAddress String @unique
firstName String
createdAt DateTime @default(now())
@@index([emailAddress]) // For lookups
@@index([createdAt]) // For sorting
@@index([firstName, lastName]) // Compound index for searches
}
```
### 5. Enums
```prisma
// ✅ CORRECT: Use enums for constrained values
enum UserRole {
USER
ADMIN
MODERATOR
}
model User {
role UserRole @default(USER)
}
// ❌ WRONG: Using strings without constraints
model User {
role String // Can be anything, no validation
}
```
## API Endpoint Design Patterns
### 1. RESTful Resource Naming
```
✅ CORRECT:
GET /api/users → List users
POST /api/users → Create user
GET /api/users/:id → Get user
PATCH /api/users/:id → Update user (partial)
PUT /api/users/:id → Replace user (full)
DELETE /api/users/:id → Delete user
GET /api/users/:id/orders → User's orders (nested resource)
POST /api/users/:id/orders → Create order for user
❌ WRONG:
GET /api/getUsers
POST /api/createUser
GET /api/user/:id (singular)
```
### 2. Query Parameters (camelCase)
```typescript
// ✅ CORRECT
GET /api/users?pageSize=20&sortBy=createdAt&orderBy=desc&isActive=true
// Query schema
const getUsersQuerySchema = z.object({
pageSize: z.coerce.number().positive().max(100).default(20),
sortBy: z.enum(['createdAt', 'firstName', 'emailAddress']).optional(),
orderBy: z.enum(['asc', 'desc']).default('desc'),
isActive: z.coerce.boolean().optional()
});
```
### 3. Response Formats
```typescript
// ✅ CORRECT: List response with pagination
{
"data": [
{ "userId": "123", "firstName": "John", "emailAddress": "john@example.com" }
],
"pagination": {
"page": 1,
"pageSize": 20,
"total": 150,
"totalPages": 8
}
}
// ✅ CORRECT: Single resource response
{
"data": {
"userId": "123",
"firstName": "John",
"emailAddress": "john@example.com",
"createdAt": "2025-01-06T12:00:00Z"
}
}
// ✅ CORRECT: Error response
{
"statusCode": 422,
"type": "ValidationError",
"message": "Invalid request data",
"details": [
{ "field": "emailAddress", "message": "Invalid email format" }
]
}
```
## Consistency Checklist
Before implementing any feature, ensure consistency with the existing codebase:
- [ ] Reviewed existing route patterns
- [ ] Checked naming conventions (all camelCase)
- [ ] Verified error handling approach
- [ ] Confirmed middleware usage patterns
- [ ] Validated layering approach (routes → controllers → services → repositories)
- [ ] Checked for reusable utilities
- [ ] Confirmed validation patterns (Zod schemas)
- [ ] Verified test structure
**NEVER introduce new patterns without explicit approval.**

# ElysiaJS Development Skill
Always consult [elysiajs.com/llms.txt](https://elysiajs.com/llms.txt) for code examples and latest API.
## Overview
ElysiaJS is a TypeScript framework for building Bun-first (but not limited to Bun) type-safe, high-performance backend servers. This skill provides comprehensive guidance for developing with Elysia, including routing, validation, authentication, plugins, integrations, and deployment.
## When to Use This Skill
Trigger this skill when the user asks to:
- Create or modify ElysiaJS routes, handlers, or servers
- Setup validation with TypeBox or other schema libraries (Zod, Valibot)
- Implement authentication (JWT, session-based, macros, guards)
- Add plugins (CORS, OpenAPI, Static files, JWT)
- Integrate with external services (Drizzle ORM, Better Auth, Next.js, Eden Treaty)
- Setup WebSocket endpoints for real-time features
- Create unit tests for Elysia instances
- Deploy Elysia servers to production
## Quick Start
Quick scaffold:
```bash
bun create elysia app
```
### Basic Server
```typescript
import { Elysia, t, status } from 'elysia'
const app = new Elysia()
.get('/', () => 'Hello World')
.post('/user', ({ body }) => body, {
body: t.Object({
name: t.String(),
age: t.Number()
})
})
.get('/id/:id', ({ params: { id } }) => {
if(id > 1_000_000) return status(404, 'Not Found')
return id
}, {
params: t.Object({
id: t.Number({
minimum: 1
})
}),
response: {
200: t.Number(),
404: t.Literal('Not Found')
}
})
.listen(3000)
```
## Basic Usage
### HTTP Methods
```typescript
import { Elysia } from 'elysia'
new Elysia()
.get('/', 'GET')
.post('/', 'POST')
.put('/', 'PUT')
.patch('/', 'PATCH')
.delete('/', 'DELETE')
.options('/', 'OPTIONS')
.head('/', 'HEAD')
```
### Path Parameters
```typescript
.get('/user/:id', ({ params: { id } }) => id)
.get('/post/:id/:slug', ({ params }) => params)
```
### Query Parameters
```typescript
.get('/search', ({ query }) => query.q)
// GET /search?q=elysia → "elysia"
```
### Request Body
```typescript
.post('/user', ({ body }) => body)
```
### Headers
```typescript
.get('/', ({ headers }) => headers.authorization)
```
## TypeBox Validation
### Basic Types
```typescript
import { Elysia, t } from 'elysia'
.post('/user', ({ body }) => body, {
body: t.Object({
name: t.String(),
age: t.Number(),
email: t.String({ format: 'email' }),
website: t.Optional(t.String({ format: 'uri' }))
})
})
```
### Nested Objects
```typescript
body: t.Object({
user: t.Object({
name: t.String(),
address: t.Object({
street: t.String(),
city: t.String()
})
})
})
```
### Arrays
```typescript
body: t.Object({
tags: t.Array(t.String()),
users: t.Array(t.Object({
id: t.String(),
name: t.String()
}))
})
```
### File Upload
```typescript
.post('/upload', ({ body }) => body.file, {
body: t.Object({
file: t.File({
type: 'image', // image/* mime types
maxSize: '5m' // 5 megabytes
}),
files: t.Files({ // Multiple files
type: ['image/png', 'image/jpeg']
})
})
})
```
### Response Validation
```typescript
.get('/user/:id', ({ params: { id } }) => ({
id,
name: 'John',
email: 'john@example.com'
}), {
params: t.Object({
id: t.Number()
}),
response: {
200: t.Object({
id: t.Number(),
name: t.String(),
email: t.String()
}),
404: t.String()
}
})
```
## Standard Schema (Zod, Valibot, ArkType)
### Zod
```typescript
import { z } from 'zod'
.post('/user', ({ body }) => body, {
body: z.object({
name: z.string(),
age: z.number().min(0),
email: z.string().email()
})
})
```
## Error Handling
```typescript
.get('/user/:id', ({ params: { id }, status }) => {
const user = findUser(id)
if (!user) {
return status(404, 'User not found')
}
return user
})
```
## Guards (Apply to Multiple Routes)
```typescript
.guard({
params: t.Object({
id: t.Number()
})
}, app => app
.get('/user/:id', ({ params: { id } }) => id)
.delete('/user/:id', ({ params: { id } }) => id)
)
```
## Macro
```typescript
.macro({
hi: (word: string) => ({
beforeHandle() { console.log(word) }
})
})
.get('/', () => 'hi', { hi: 'Elysia' })
```
### Project Structure (Recommended)
Elysia takes an unopinionated approach but based on user request. But without any specific preference, we recommend a feature-based and domain driven folder structure where each feature has its own folder containing controllers, services, and models.
```
src/
├── index.ts # Main server entry
├── modules/
│ ├── auth/
│ │ ├── index.ts # Auth routes (Elysia instance)
│ │ ├── service.ts # Business logic
│ │ └── model.ts # TypeBox schemas/DTOs
│ └── user/
│ ├── index.ts
│ ├── service.ts
│ └── model.ts
└── plugins/
└── custom.ts
public/ # Static files (if using static plugin)
test/ # Unit tests
```
Each file has its own responsibility as follows:
- **Controller (index.ts)**: Handle HTTP routing, request validation, and cookie.
- **Service (service.ts)**: Handle business logic, decoupled from Elysia controller if possible.
- **Model (model.ts)**: Define the data structure and validation for the request and response.
## Best Practice
Elysia is unopinionated on design pattern, but if not provided, we can relies on MVC pattern pair with feature based folder structure.
- Controller:
- Prefers Elysia as a controller for HTTP dependant controller
- For non HTTP dependent, prefers service instead unless explicitly asked
- Use `onError` to handle local custom errors
- Register Model to Elysia instance via `Elysia.models({ ...models })` and prefix model by namespace `Elysia.prefix('model', 'Namespace.')
- Prefers Reference Model by name provided by Elysia instead of using an actual `Model.name`
- Service:
- Prefers class (or abstract class if possible)
- Prefers interface/type derive from `Model`
- Return `status` (`import { status } from 'elysia'`) for error
- Prefers `return Error` instead of `throw Error`
- Models:
- Always export validation model and type of validation model
- Custom Error should be in contains in Model
## Elysia Key Concept
Elysia has a every important concepts/rules to understand before use.
## Encapsulation - Isolates by Default
Lifecycles (hooks, middleware) **don't leak** between instances unless scoped.
**Scope levels:**
- `local` (default) - current instance + descendants
- `scoped` - parent + current + descendants
- `global` - all instances
```ts
.onBeforeHandle(() => {}) // only local instance
.onBeforeHandle({ as: 'global' }, () => {}) // exports to all
```
## Method Chaining - Required for Types
**Must chain**. Each method returns new type reference.
❌ Don't:
```ts
const app = new Elysia()
app.state('build', 1) // loses type
app.get('/', ({ store }) => store.build) // build doesn't exists
```
✅ Do:
```ts
new Elysia()
.state('build', 1)
.get('/', ({ store }) => store.build)
```
## Explicit Dependencies
Each instance independent. **Declare what you use.**
```ts
const auth = new Elysia()
.decorate('Auth', Auth)
.model(Auth.models)
new Elysia()
.get('/', ({ Auth }) => Auth.getProfile()) // Auth doesn't exists
new Elysia()
.use(auth) // must declare
.get('/', ({ Auth }) => Auth.getProfile())
```
**Global scope when:**
- No types added (cors, helmet)
- Global lifecycle (logging, tracing)
**Explicit when:**
- Adds types (state, models)
- Business logic (auth, db)
## Deduplication
Plugins re-execute unless named:
```ts
new Elysia() // rerun on `.use`
new Elysia({ name: 'ip' }) // runs once across all instances
```
## Order Matters
Events apply to routes **registered after** them.
```ts
.onBeforeHandle(() => console.log('1'))
.get('/', () => 'hi') // has hook
.onBeforeHandle(() => console.log('2')) // doesn't affect '/'
```
## Type Inference
**Inline functions only** for accurate types.
For controllers, destructure in inline wrapper:
```ts
.post('/', ({ body }) => Controller.greet(body), {
body: t.Object({ name: t.String() })
})
```
Get type from schema:
```ts
type MyType = typeof MyType.static
```
## Reference Model
Model can be reference by name, especially great for documenting an API
```ts
new Elysia()
.model({
book: t.Object({
name: t.String()
})
})
.post('/', ({ body }) => body.name, {
body: 'book'
})
```
Model can be renamed by using `.prefix` / `.suffix`
```ts
new Elysia()
.model({
book: t.Object({
name: t.String()
})
})
.prefix('model', 'Namespace')
.post('/', ({ body }) => body.name, {
body: 'Namespace.Book'
})
```
Once `prefix`, model name will be capitalized by default.
## Technical Terms
The following are technical terms that is use for Elysia:
- `OpenAPI Type Gen` - function name `fromTypes` from `@elysiajs/openapi` for generating OpenAPI from types, see `plugins/openapi.md`
- `Eden`, `Eden Treaty` - e2e type safe RPC client for share type from backend to frontend

# AI SDK Integration
## What It Is
Seamless integration with Vercel AI SDK via response streaming.
## Response Streaming
Return `ReadableStream` or `Response` directly:
```typescript
import { streamText } from 'ai'
import { openai } from '@ai-sdk/openai'
new Elysia().get('/', () => {
const stream = streamText({
model: openai('gpt-5'),
system: 'You are Yae Miko from Genshin Impact',
prompt: 'Hi! How are you doing?'
})
return stream.textStream // ReadableStream
// or
return stream.toUIMessageStream() // UI Message Stream
})
```
Elysia auto-handles stream.
## Server-Sent Events
Wrap `ReadableStream` with `sse`:
```typescript
import { sse } from 'elysia'
.get('/', () => {
const stream = streamText({ /* ... */ })
return sse(stream.textStream)
// or
return sse(stream.toUIMessageStream())
})
```
Each chunk → SSE.
## As Response
Return stream directly (no Eden type safety):
```typescript
.get('/', () => {
const stream = streamText({ /* ... */ })
return stream.toTextStreamResponse()
// or
return stream.toUIMessageStreamResponse() // Uses SSE
})
```
## Manual Streaming
Generator function for control:
```typescript
import { sse } from 'elysia'
.get('/', async function* () {
const stream = streamText({ /* ... */ })
for await (const data of stream.textStream)
yield sse({ data, event: 'message' })
yield sse({ event: 'done' })
})
```
## Fetch for Unsupported Models
Direct fetch with streaming proxy:
```typescript
.get('/', () => {
return fetch('https://api.openai.com/v1/chat/completions', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
Authorization: `Bearer ${process.env.OPENAI_API_KEY}`
},
body: JSON.stringify({
model: 'gpt-5',
stream: true,
messages: [
{ role: 'system', content: 'You are Yae Miko' },
{ role: 'user', content: 'Hi! How are you doing?' }
]
})
})
})
```
Elysia auto-proxies fetch response with streaming.

# Astro Integration - SKILLS.md
## What It Is
Run Elysia on Astro via Astro Endpoint.
## Setup
1. Set output to server:
```javascript
// astro.config.mjs
export default defineConfig({
output: 'server'
})
```
2. Create `pages/[...slugs].ts`
3. Define Elysia server + export handlers:
```typescript
// pages/[...slugs].ts
import { Elysia, t } from 'elysia'
const app = new Elysia()
.get('/api', () => 'hi')
.post('/api', ({ body }) => body, {
body: t.Object({ name: t.String() })
})
const handle = ({ request }: { request: Request }) => app.handle(request)
export const GET = handle
export const POST = handle
```
WinterCG compliance - works normally.
Recommended: Run Astro on Bun (Elysia designed for Bun).
## Prefix for Non-Root
If placed in `pages/api/[...slugs].ts`, set prefix:
```typescript
// pages/api/[...slugs].ts
const app = new Elysia({ prefix: '/api' })
.get('/', () => 'hi')
const handle = ({ request }: { request: Request }) => app.handle(request)
export const GET = handle
export const POST = handle
```
Ensures routing works in any location.
## Benefits
Co-location of frontend + backend. End-to-end type safety with Eden.
## pnpm
Manual install:
```bash
pnpm add @sinclair/typebox openapi-types
```

# Better Auth Integration
Elysia + Better Auth integration guide
## What It Is
Framework-agnostic TypeScript auth/authz. Comprehensive features + plugin ecosystem.
## Setup
```typescript
import { betterAuth } from 'better-auth'
import { Pool } from 'pg'
export const auth = betterAuth({
database: new Pool()
})
```
## Handler Mounting
```typescript
import { auth } from './auth'
new Elysia()
.mount(auth.handler) // http://localhost:3000/api/auth
.listen(3000)
```
### Custom Endpoint
```typescript
// Mount with prefix
.mount('/auth', auth.handler) // http://localhost:3000/auth/api/auth
// Customize basePath
export const auth = betterAuth({
basePath: '/api' // http://localhost:3000/auth/api
})
```
Cannot set `basePath` to empty or `/`.
## OpenAPI Integration
Extract docs from Better Auth:
```typescript
import { openAPI } from 'better-auth/plugins'
let _schema: ReturnType<typeof auth.api.generateOpenAPISchema>
const getSchema = async () => (_schema ??= auth.api.generateOpenAPISchema())
export const OpenAPI = {
getPaths: (prefix = '/auth/api') =>
getSchema().then(({ paths }) => {
const reference: typeof paths = Object.create(null)
for (const path of Object.keys(paths)) {
const key = prefix + path
reference[key] = paths[path]
for (const method of Object.keys(paths[path])) {
const operation = (reference[key] as any)[method]
operation.tags = ['Better Auth']
}
}
return reference
}) as Promise<any>,
components: getSchema().then(({ components }) => components) as Promise<any>
} as const
```
Apply to Elysia:
```typescript
new Elysia().use(openapi({
documentation: {
components: await OpenAPI.components,
paths: await OpenAPI.getPaths()
}
}))
```
## CORS
```typescript
import { cors } from '@elysiajs/cors'
new Elysia()
.use(cors({
origin: 'http://localhost:3001',
methods: ['GET', 'POST', 'PUT', 'DELETE', 'OPTIONS'],
credentials: true,
allowedHeaders: ['Content-Type', 'Authorization']
}))
.mount(auth.handler)
```
## Macro for Auth
Use macro + resolve for session/user:
```typescript
const betterAuth = new Elysia({ name: 'better-auth' })
.mount(auth.handler)
.macro({
auth: {
async resolve({ status, request: { headers } }) {
const session = await auth.api.getSession({ headers })
if (!session) return status(401)
return {
user: session.user,
session: session.session
}
}
}
})
new Elysia()
.use(betterAuth)
.get('/user', ({ user }) => user, { auth: true })
```
Access `user` and `session` in all routes.

# Cloudflare Worker Integration
## What It Is
**Experimental** Cloudflare Worker adapter for Elysia.
## Setup
1. Install Wrangler:
```bash
wrangler init elysia-on-cloudflare
```
2. Apply adapter + compile:
```typescript
import { Elysia } from 'elysia'
import { CloudflareAdapter } from 'elysia/adapter/cloudflare-worker'
export default new Elysia({
adapter: CloudflareAdapter
})
.get('/', () => 'Hello Cloudflare Worker!')
.compile() // Required
```
3. Set compatibility date (min `2025-06-01`):
```json
// wrangler.json
{
"name": "elysia-on-cloudflare",
"main": "src/index.ts",
"compatibility_date": "2025-06-01"
}
```
4. Dev server:
```bash
wrangler dev
# http://localhost:8787
```
No `nodejs_compat` flag needed.
## Limitations
1. `Elysia.file` + Static Plugin don't work (no `fs` module)
2. OpenAPI Type Gen doesn't work (no `fs` module)
3. Cannot define Response before server start
4. Cannot inline values:
```typescript
// ❌ Throws error
.get('/', 'Hello Elysia')
// ✅ Works
.get('/', () => 'Hello Elysia')
```
## Static Files
Use Cloudflare's built-in static serving:
```json
// wrangler.json
{
"assets": { "directory": "public" }
}
```
Structure:
```
├─ public
│ ├─ kyuukurarin.mp4
│ └─ static/mika.webp
```
Access:
- `http://localhost:8787/kyuukurarin.mp4`
- `http://localhost:8787/static/mika.webp`
## Binding
Import env from `cloudflare:workers`:
```typescript
import { env } from 'cloudflare:workers'
export default new Elysia({ adapter: CloudflareAdapter })
.get('/', () => `Hello ${await env.KV.get('my-key')}`)
.compile()
```
## AoT Compilation
As of Elysia 1.4.7, AoT works with Cloudflare Worker. Drop `aot: false` flag.
Cloudflare now supports Function compilation during startup.
## pnpm
Manual install:
```bash
pnpm add @sinclair/typebox openapi-types

# Drizzle Integration
Elysia + Drizzle integration guide
## What It Is
Headless TypeScript ORM. Convert Drizzle schema → Elysia validation models via `drizzle-typebox`.
## Flow
```
Drizzle → drizzle-typebox → Elysia validation → OpenAPI + Eden Treaty
```
## Installation
```bash
bun add drizzle-orm drizzle-typebox
```
### Pin TypeBox Version
Prevent Symbol conflicts:
```bash
grep "@sinclair/typebox" node_modules/elysia/package.json
```
Add to `package.json`:
```json
{
"overrides": {
"@sinclair/typebox": "0.32.4"
}
}
```
## Drizzle Schema
```typescript
// src/database/schema.ts
import { pgTable, varchar, timestamp } from 'drizzle-orm/pg-core'
import { createId } from '@paralleldrive/cuid2'
export const user = pgTable('user', {
id: varchar('id').$defaultFn(() => createId()).primaryKey(),
username: varchar('username').notNull().unique(),
password: varchar('password').notNull(),
email: varchar('email').notNull().unique(),
salt: varchar('salt', { length: 64 }).notNull(),
createdAt: timestamp('created_at').defaultNow().notNull()
})
export const table = { user } as const
export type Table = typeof table
```
## drizzle-typebox
```typescript
import { t } from 'elysia'
import { createInsertSchema } from 'drizzle-typebox'
import { table } from './database/schema'
const _createUser = createInsertSchema(table.user, {
email: t.String({ format: 'email' }) // Replace with Elysia type
})
new Elysia()
.post('/sign-up', ({ body }) => {}, {
body: t.Omit(_createUser, ['id', 'salt', 'createdAt'])
})
```
## Type Instantiation Error
**Error**: "Type instantiation is possibly infinite"
**Cause**: Circular reference when nesting drizzle-typebox into Elysia schema.
**Fix**: Explicitly define type between them:
```typescript
// ✅ Works
const _createUser = createInsertSchema(table.user, {
email: t.String({ format: 'email' })
})
const createUser = t.Omit(_createUser, ['id', 'salt', 'createdAt'])
// ❌ Infinite loop
const createUser = t.Omit(
createInsertSchema(table.user, { email: t.String({ format: 'email' }) }),
['id', 'salt', 'createdAt']
)
```
Always declare variable for drizzle-typebox then reference it.
## Utility Functions
Copy as-is for simplified usage:
```typescript
// src/database/utils.ts
/**
* @lastModified 2025-02-04
* @see https://elysiajs.com/recipe/drizzle.html#utility
*/
import { Kind, type TObject } from '@sinclair/typebox'
import {
createInsertSchema,
createSelectSchema,
BuildSchema,
} from 'drizzle-typebox'
import { table } from './schema'
import type { Table } from 'drizzle-orm'
type Spread<
T extends TObject | Table,
Mode extends 'select' | 'insert' | undefined,
> =
T extends TObject<infer Fields>
? {
[K in keyof Fields]: Fields[K]
}
: T extends Table
? Mode extends 'select'
? BuildSchema<
'select',
T['_']['columns'],
undefined
>['properties']
: Mode extends 'insert'
? BuildSchema<
'insert',
T['_']['columns'],
undefined
>['properties']
: {}
: {}
/**
* Spread a Drizzle schema into a plain object
*/
export const spread = <
T extends TObject | Table,
Mode extends 'select' | 'insert' | undefined,
>(
schema: T,
mode?: Mode,
): Spread<T, Mode> => {
const newSchema: Record<string, unknown> = {}
let table
switch (mode) {
case 'insert':
case 'select':
if (Kind in schema) {
table = schema
break
}
table =
mode === 'insert'
? createInsertSchema(schema)
: createSelectSchema(schema)
break
default:
if (!(Kind in schema)) throw new Error('Expect a schema')
table = schema
}
for (const key of Object.keys(table.properties))
newSchema[key] = table.properties[key]
return newSchema as any
}
/**
* Spread a Drizzle Table into a plain object
*
* If `mode` is 'insert', the schema will be refined for insert
* If `mode` is 'select', the schema will be refined for select
* If `mode` is undefined, the schema will be spread as is, models will need to be refined manually
*/
export const spreads = <
T extends Record<string, TObject | Table>,
Mode extends 'select' | 'insert' | undefined,
>(
models: T,
mode?: Mode,
): {
[K in keyof T]: Spread<T[K], Mode>
} => {
const newSchema: Record<string, unknown> = {}
const keys = Object.keys(models)
for (const key of keys) newSchema[key] = spread(models[key], mode)
return newSchema as any
}
```
Usage:
```typescript
// ✅ Using spread
const user = spread(table.user, 'insert')
const createUser = t.Object({
id: user.id,
username: user.username,
password: user.password
})
// ⚠️ Using t.Pick
const _createUser = createInsertSchema(table.user)
const createUser = t.Pick(_createUser, ['id', 'username', 'password'])
```
## Table Singleton Pattern
```typescript
// src/database/model.ts
import { table } from './schema'
import { spreads } from './utils'
export const db = {
insert: spreads({ user: table.user }, 'insert'),
select: spreads({ user: table.user }, 'select')
} as const
```
Usage:
```typescript
// src/index.ts
import { db } from './database/model'
const { user } = db.insert
new Elysia()
.post('/sign-up', ({ body }) => {}, {
body: t.Object({
id: user.username,
username: user.username,
password: user.password
})
})
```
## Refinement
```typescript
// src/database/model.ts
import { createInsertSchema, createSelectSchema } from 'drizzle-typebox'
export const db = {
insert: spreads({
user: createInsertSchema(table.user, {
email: t.String({ format: 'email' })
})
}, 'insert'),
select: spreads({
user: createSelectSchema(table.user, {
email: t.String({ format: 'email' })
})
}, 'select')
} as const
```
`spread` skips refined schemas.

# Expo Integration
Run Elysia on Expo (React Native)
## What It Is
Create API routes in Expo app (SDK 50+, App Router v3).
## Setup
1. Create `app/[...slugs]+api.ts`
2. Define Elysia server
3. Export `Elysia.fetch` as HTTP methods
```typescript
// app/[...slugs]+api.ts
import { Elysia, t } from 'elysia'
const app = new Elysia()
.get('/', 'hello Expo')
.post('/', ({ body }) => body, {
body: t.Object({ name: t.String() })
})
export const GET = app.fetch
export const POST = app.fetch
```
## Prefix for Non-Root
If placed in `app/api/[...slugs]+api.ts`, set prefix:
```typescript
const app = new Elysia({ prefix: '/api' })
.get('/', 'Hello Expo')
export const GET = app.fetch
export const POST = app.fetch
```
Ensures routing works in any location.
## Eden (End-to-End Type Safety)
1. Export type:
```typescript
// app/[...slugs]+api.ts
const app = new Elysia()
.get('/', 'Hello Nextjs')
.post('/user', ({ body }) => body, {
body: treaty.schema('User', { name: 'string' })
})
export type app = typeof app
export const GET = app.fetch
export const POST = app.fetch
```
2. Create client:
```typescript
// lib/eden.ts
import { treaty } from '@elysiajs/eden'
import type { app } from '../app/[...slugs]+api'
export const api = treaty<app>('localhost:3000/api')
```
3. Use in components:
```tsx
// app/page.tsx
import { api } from '../lib/eden'
export default async function Page() {
const message = await api.get()
return <h1>Hello, {message}</h1>
}
```
## Deployment
- Deploy as normal Elysia app OR
- Use experimental Expo server runtime
With Expo runtime:
```bash
expo export
# Creates dist/server/_expo/functions/[...slugs]+api.js
```
Edge function, not normal server (no port allocation).
### Adapters
- Express
- Netlify
- Vercel

# Next.js Integration
## What It Is
Run Elysia on Next.js App Router.
## Setup
1. Create `app/api/[[...slugs]]/route.ts`
2. Define Elysia + export handlers:
```typescript
// app/api/[[...slugs]]/route.ts
import { Elysia, t } from 'elysia'
const app = new Elysia({ prefix: '/api' })
.get('/', 'Hello Nextjs')
.post('/', ({ body }) => body, {
body: t.Object({ name: t.String() })
})
export const GET = app.fetch
export const POST = app.fetch
```
WinterCG compliance - works as normal Next.js API route.
## Prefix for Non-Root
If placed in `app/user/[[...slugs]]/route.ts`, set prefix:
```typescript
const app = new Elysia({ prefix: '/user' })
.get('/', 'Hello Nextjs')
export const GET = app.fetch
export const POST = app.fetch
```
## Eden (End-to-End Type Safety)
Isomorphic fetch pattern:
- Server: Direct calls (no network)
- Client: Network calls
1. Export type:
```typescript
// app/api/[[...slugs]]/route.ts
export const app = new Elysia({ prefix: '/api' })
.get('/', 'Hello Nextjs')
.post('/user', ({ body }) => body, {
body: treaty.schema('User', { name: 'string' })
})
export type app = typeof app
export const GET = app.fetch
export const POST = app.fetch
```
2. Create client:
```typescript
// lib/eden.ts
import { treaty } from '@elysiajs/eden'
import type { app } from '../app/api/[[...slugs]]/route'
export const api =
typeof process !== 'undefined'
? treaty(app).api
: treaty<typeof app>('localhost:3000').api
```
Use `typeof process` not `typeof window` (window undefined at build time → hydration error).
3. Use in components:
```tsx
// app/page.tsx
import { api } from '../lib/eden'
export default async function Page() {
const message = await api.get()
return <h1>Hello, {message}</h1>
}
```
Works with server/client components + ISR.
## React Query
```tsx
import { useQuery } from '@tanstack/react-query'
function App() {
const { data: response } = useQuery({
queryKey: ['get'],
queryFn: () => getTreaty().get()
})
return response?.data
}
```
Works with all React Query features.

})
```
2. Create `api.ts` at project root:
```typescript
// api.ts
export default () => new Elysia()
.get('/hello', () => ({ message: 'Hello world!' }))
```
3. Use Eden Treaty:
```vue
<template>
<div>
<p>{{ data.message }}</p>
</div>
</template>
<script setup lang="ts">
const { $api } = useNuxtApp()
const { data } = await useAsyncData(async () => {
const { data, error } = await $api.hello.get()
if (error) throw new Error('Failed to call API')
return data
})
</script>
```
Auto-setup on Nuxt API route.
## Prefix
Default: `/_api`. Customize:
```typescript
export default defineNuxtConfig({
nuxtElysia: {
path: '/api'
}
})
```
Mounts on `/api` instead of `/_api`.

# Prisma Integration
Elysia + Prisma integration guide
## What It Is
Type-safe ORM. Generate Elysia validation models from Prisma schema via `prismabox`.
## Flow
```
Prisma → prismabox → Elysia validation → OpenAPI + Eden Treaty
```
## Installation
```bash
bun add @prisma/client prismabox && \
bun add -d prisma
```
## Prisma Schema
Add `prismabox` generator:
```prisma
// prisma/schema.prisma
generator client {
provider = "prisma-client"
output = "../generated/prisma"
}
datasource db {
provider = "sqlite"
url = env("DATABASE_URL")
}
generator prismabox {
provider = "prismabox"
typeboxImportDependencyName = "elysia"
typeboxImportVariableName = "t"
inputModel = true
output = "../generated/prismabox"
}
model User {
id String @id @default(cuid())
email String @unique
name String?
posts Post[]
}
model Post {
id String @id @default(cuid())
title String
content String?
published Boolean @default(false)
author User @relation(fields: [authorId], references: [id])
authorId String
}
```
Generates:
- `User``generated/prismabox/User.ts`
- `Post``generated/prismabox/Post.ts`
## Using Generated Models
```typescript
// src/index.ts
import { Elysia, t } from 'elysia'
import { PrismaClient } from '../generated/prisma'
import { UserPlain, UserPlainInputCreate } from '../generated/prismabox/User'
const prisma = new PrismaClient()
new Elysia()
.put('/', async ({ body }) =>
prisma.user.create({ data: body }), {
body: UserPlainInputCreate,
response: UserPlain
}
)
.get('/id/:id', async ({ params: { id }, status }) => {
const user = await prisma.user.findUnique({ where: { id } })
if (!user) return status(404, 'User not found')
return user
}, {
response: {
200: UserPlain,
404: t.String()
}
})
.listen(3000)

# React Email Integration
## What It Is
Use React components to create emails. Direct JSX import via Bun.
## Installation
```bash
bun add -d react-email
bun add @react-email/components react react-dom
```
Script in `package.json`:
```json
{
"scripts": {
"email": "email dev --dir src/emails"
}
}
```
Email templates → `src/emails` directory.
### TypeScript
Add to `tsconfig.json`:
```json
{
"compilerOptions": {
"jsx": "react"
}
}
```
## Email Template
```tsx
// src/emails/otp.tsx
import * as React from 'react'
import { Tailwind, Section, Text } from '@react-email/components'
export default function OTPEmail({ otp }: { otp: number }) {
return (
<Tailwind>
<Section className="flex justify-center items-center w-full min-h-screen font-sans">
<Section className="flex flex-col items-center w-76 rounded-2xl px-6 py-1 bg-gray-50">
<Text className="text-xs font-medium text-violet-500">
Verify your Email Address
</Text>
<Text className="text-gray-500 my-0">
Use the following code to verify your email address
</Text>
<Text className="text-5xl font-bold pt-2">{otp}</Text>
<Text className="text-gray-400 font-light text-xs pb-4">
This code is valid for 10 minutes
</Text>
<Text className="text-gray-600 text-xs">
Thank you for joining us
</Text>
</Section>
</Section>
</Tailwind>
)
}
OTPEmail.PreviewProps = { otp: 123456 }
```
`@react-email/components` → email-client compatible (Gmail, Outlook). Tailwind support.
`PreviewProps` → playground only.
## Preview
```bash
bun email
```
Opens browser with preview.
## Send Email
Render with `react-dom/server`, submit via provider:
### Nodemailer
```typescript
import { renderToStaticMarkup } from 'react-dom/server'
import OTPEmail from './emails/otp'
import nodemailer from 'nodemailer'
const transporter = nodemailer.createTransport({
host: 'smtp.gehenna.sh',
port: 465,
auth: { user: 'makoto', pass: '12345678' }
})
.get('/otp', async ({ body }) => {
const otp = ~~(Math.random() * 900_000) + 100_000
const html = renderToStaticMarkup(<OTPEmail otp={otp} />)
await transporter.sendMail({
from: '[email protected]',
to: body,
subject: 'Verify your email address',
html
})
return { success: true }
}, {
body: t.String({ format: 'email' })
})
```
### Resend
```typescript
import OTPEmail from './emails/otp'
import Resend from 'resend'
const resend = new Resend('re_123456789')
.get('/otp', ({ body }) => {
const otp = ~~(Math.random() * 900_000) + 100_000
await resend.emails.send({
from: '[email protected]',
to: body,
subject: 'Verify your email address',
html: <OTPEmail otp={otp} /> // Direct JSX
})
return { success: true }
})
```
Direct JSX import thanks to Bun.
Other providers: AWS SES, SendGrid.

}
export const fallback = ({ request }: WithRequest) => app.handle(request)
```
Treat as normal SvelteKit server route.
## Prefix for Non-Root
If placed in `src/routes/api/[...slugs]/+server.ts`, set prefix:
```typescript
// src/routes/api/[...slugs]/+server.ts

# Tanstack Start Integration
## What It Is
Elysia runs inside Tanstack Start server routes.
## Setup
1. Create `src/routes/api.$.ts`
2. Define Elysia server
3. Export handlers in `server.handlers`:
```typescript
// src/routes/api.$.ts
import { Elysia } from 'elysia'
import { createFileRoute } from '@tanstack/react-router'
import { createIsomorphicFn } from '@tanstack/react-start'
const app = new Elysia({

const handle = ({ request }: { request: Request }) => app.fetch(request)
export const Route = createFileRoute('/api/$')({
server: {
handlers: {
GET: handle,
POST: handle
}
}
})
```
Runs on `/api`. Add methods to `server.handlers` as needed.
## Eden (End-to-End Type Safety)
Isomorphic pattern with `createIsomorphicFn`:
```typescript
// src/routes/api.$.ts
export const getTreaty = createIsomorphicFn()
.server(() => treaty(app).api)
.client(() => treaty<typeof app>('localhost:3000').api)
```
- Server: Direct call (no HTTP overhead)
- Client: HTTP call
## Loader Data
Fetch before render:
```tsx
// src/routes/index.tsx
import { createFileRoute } from '@tanstack/react-router'
import { getTreaty } from './api.$'
export const Route = createFileRoute('/a')({
component: App,
loader: () => getTreaty().get().then((res) => res.data)
})
function App() {
const data = Route.useLoaderData()
return data
}
```
Executed server-side during SSR. No HTTP overhead. Type-safe.
## React Query
```tsx
import { useQuery } from '@tanstack/react-query'
import { getTreaty } from './api.$'
function App() {
const { data: response } = useQuery({
queryKey: ['get'],
queryFn: () => getTreaty().get()

# MVC pattern
This file contains a guideline for using Elysia with MVC or Model View Controller patterns
- Controller:
- Prefers Elysia as a controller for HTTP dependant
- For non HTTP dependent, prefers service instead unless explicitly asked
- Use `onError` to handle local custom errors
- Register Model to Elysia instance via `Elysia.models({ ...models })` and prefix model by namespace `Elysia.prefix('model', 'Namespace.')
- Prefers Reference Model by name provided by Elysia instead of using an actual `Model.name`
- Service:
- Prefers class (or abstract class if possible)
- Prefers interface/type derive from `Model`
- Return `status` (`import { status } from 'elysia'`) for error
- Prefers `return Error` instead of `throw Error`
- Models:
- Always export validation model and type of validation model
- Custom Error should be in contains in Model
## Controller
Due to type soundness of Elysia, it's not recommended to use a traditional controller class that is tightly coupled with Elysia's `Context` because:
1. **Elysia type is complex** and heavily depends on plugin and multiple level of chaining.
2. **Hard to type**, Elysia type could change at anytime, especially with decorators, and store
3. **Loss of type integrity**, and inconsistency between types and runtime code.
We recommended one of the following approach to implement a controller in Elysia.
1. Use Elysia instance as a controller itself
2. Create a controller that is not tied with HTTP request or Elysia.
---
### 1. Elysia instance as a controller
> 1 Elysia instance = 1 controller
Treat an Elysia instance as a controller, and define your routes directly on the Elysia instance.
```typescript
// Do
import { Elysia } from 'elysia'
import { Service } from './service'
new Elysia()
.get('/', ({ stuff }) => {
Service.doStuff(stuff)
})
```
This approach allows Elysia to infer the `Context` type automatically, ensuring type integrity and consistency between types and runtime code.
```typescript
// Don't
import { Elysia, t, type Context } from 'elysia'
abstract class Controller {
static root(context: Context) {
return Service.doStuff(context.stuff)
}
}
new Elysia()
.get('/', Controller.root)
```
This approach makes it hard to type `Context` properly, and may lead to loss of type integrity.
### 2. Controller without HTTP request
If you want to create a controller class, we recommend creating a class that is not tied to HTTP request or Elysia at all.
This approach allows you to decouple the controller from Elysia, making it easier to test, reuse, and even swap a framework while still follows the MVC pattern.
```typescript
import { Elysia } from 'elysia'
abstract class Controller {
static doStuff(stuff: string) {
return Service.doStuff(stuff)
}
}
new Elysia()
.get('/', ({ stuff }) => Controller.doStuff(stuff))
```
Tying the controller to Elysia Context may lead to:
1. Loss of type integrity
2. Make it harder to test and reuse
3. Lead to vendor lock-in
We recommended to keep the controller decoupled from Elysia as much as possible.
### Don't: Pass entire `Context` to a controller
**Context is a highly dynamic type** that can be inferred from Elysia instance.
Do not pass an entire `Context` to a controller, instead use object destructuring to extract what you need and pass it to the controller.
```typescript
import type { Context } from 'elysia'
abstract class Controller {
constructor() {}
// Don't do this
static root(context: Context) {
return Service.doStuff(context.stuff)
}
}
```
This approach makes it hard to type `Context` properly, and may lead to loss of type integrity.
### Testing
If you're using Elysia as a controller, you can test your controller using `handle` to directly call a function (and it's lifecycle)
```typescript
import { Elysia } from 'elysia'
import { Service } from './service'
import { describe, it, expect } from 'bun:test'
const app = new Elysia()
.get('/', ({ stuff }) => {
Service.doStuff(stuff)
return 'ok'
})
describe('Controller', () => {
it('should work', async () => {
const response = await app
.handle(new Request('http://localhost/'))
.then((x) => x.text())
expect(response).toBe('ok')
})
})
```
You may find more information about testing in [Unit Test](/patterns/unit-test.html).
## Service
Service is a set of utility/helper functions decoupled as a business logic to use in a module/controller, in our case, an Elysia instance.
Any technical logic that can be decoupled from controller may live inside a **Service**.
There are 2 types of service in Elysia:
1. Non-request dependent service
2. Request dependent service
### 1. Abstract away Non-request dependent service
We recommend abstracting a service class/function away from Elysia.
If the service or function isn't tied to an HTTP request or doesn't access a `Context`, it's recommended to implement it as a static class or function.
```typescript
import { Elysia, t } from 'elysia'
abstract class Service {
static fibo(number: number): number {
if(number < 2)
return number
return Service.fibo(number - 1) + Service.fibo(number - 2)
}
}
new Elysia()
.get('/fibo', ({ body }) => {
return Service.fibo(body)
}, {
body: t.Numeric()
})
```
If your service doesn't need to store a property, you may use `abstract class` and `static` instead to avoid allocating class instance.
### 2. Request dependent service as Elysia instance
**If the service is a request-dependent service** or needs to process HTTP requests, we recommend abstracting it as an Elysia instance to ensure type integrity and inference:
```typescript
import { Elysia } from 'elysia'
// Do
const AuthService = new Elysia({ name: 'Auth.Service' })
.macro({
isSignIn: {
resolve({ cookie, status }) {
if (!cookie.session.value) return status(401)
return {
session: cookie.session.value,
}
}
}
})
const UserController = new Elysia()
.use(AuthService)
.get('/profile', ({ Auth: { user } }) => user, {
isSignIn: true
})
```
### Do: Decorate only request dependent property
It's recommended to `decorate` only request-dependent properties, such as `requestIP`, `requestTime`, or `session`.
Overusing decorators may tie your code to Elysia, making it harder to test and reuse.
```typescript
import { Elysia } from 'elysia'
new Elysia()
.decorate('requestIP', ({ request }) => request.headers.get('x-forwarded-for') || request.ip)
.decorate('requestTime', () => Date.now())
.decorate('session', ({ cookie }) => cookie.session.value)
.get('/', ({ requestIP, requestTime, session }) => {
return { requestIP, requestTime, session }
})
```
### Don't: Pass entire `Context` to a service
**Context is a highly dynamic type** that can be inferred from Elysia instance.
Do not pass an entire `Context` to a service, instead use object destructuring to extract what you need and pass it to the service.
```typescript
import type { Context } from 'elysia'
class AuthService {
constructor() {}
// Don't do this
isSignIn({ status, cookie: { session } }: Context) {
if (session.value)
return status(401)
}
}
```
As Elysia type is complex, and heavily depends on plugin and multiple level of chaining, it can be challenging to manually type as it's highly dynamic.
## Model
Model or [DTO (Data Transfer Object)](https://en.wikipedia.org/wiki/Data_transfer_object) is handle by [Elysia.t (Validation)](/essential/validation.html#elysia-type).
Elysia has a validation system built-in which can infers type from your code and validate it at runtime.
### Do: Use Elysia's validation system
Elysia strength is prioritizing a single source of truth for both type and runtime validation.
Instead of declaring an interface, reuse validation's model instead:
```typescript twoslash
// Do
import { Elysia, t } from 'elysia'
const customBody = t.Object({
username: t.String(),
password: t.String()
})
// Optional if you want to get the type of the model
// Usually if we didn't use the type, as it's already inferred by Elysia
type CustomBody = typeof customBody.static
export { customBody }
```
We can get type of model by using `typeof` with `.static` property from the model.
Then you can use the `CustomBody` type to infer the type of the request body.
```typescript twoslash
// Do
new Elysia()
.post('/login', ({ body }) => {
return body
}, {
body: customBody
})
```
### Don't: Declare a class instance as a model
Do not declare a class instance as a model:
```typescript
// Don't
class CustomBody {
username: string
password: string
constructor(username: string, password: string) {
this.username = username
this.password = password
}
}
// Don't
interface ICustomBody {
username: string
password: string
}
```
### Don't: Declare type separate from the model
Do not declare a type separate from the model, instead use `typeof` with `.static` property to get the type of the model.
```typescript
// Don't
import { Elysia, t } from 'elysia'
const customBody = t.Object({
username: t.String(),
password: t.String()
})
type CustomBody = {
username: string
password: string
}
// Do
const customBody = t.Object({
username: t.String(),
password: t.String()
})
type CustomBody = typeof customBody.static
```
### Group
You can group multiple models into a single object to make it more organized.
```typescript
import { Elysia, t } from 'elysia'
export const AuthModel = {
sign: t.Object({
username: t.String(),
password: t.String()
})
}
const models = AuthModel.models
```
### Model Injection
Though this is optional, if you are strictly following MVC pattern, you may want to inject like a service into a controller. We recommended using Elysia reference model
Using Elysia's model reference
```typescript twoslash
import { Elysia, t } from 'elysia'
const customBody = t.Object({
username: t.String(),
password: t.String()
})
const AuthModel = new Elysia()
.model({
sign: customBody
})
const models = AuthModel.models
const UserController = new Elysia({ prefix: '/auth' })
.use(AuthModel)
.prefix('model', 'auth.')
.post('/sign-in', async ({ body, cookie: { session } }) => {
return true
}, {
body: 'auth.Sign'
})
```
This approach provide several benefits:
1. Allow us to name a model and provide auto-completion.
2. Modify schema for later usage, or perform a [remap](/essential/handler.html#remap).
3. Show up as "models" in OpenAPI compliance client, eg. OpenAPI.
4. Improve TypeScript inference speed as model type will be cached during registration.

# CORS
Plugin for Elysia that adds support for customizing Cross-Origin Resource Sharing behavior.
## Installation
```bash
bun add @elysiajs/cors
```
## Basic Usage
```typescript twoslash
import { Elysia } from 'elysia'
import { cors } from '@elysiajs/cors'
new Elysia().use(cors()).listen(3000)
```
This will set Elysia to accept requests from any origin.
## Config
Below is a config which is accepted by the plugin
### origin
@default `true`
Indicates whether the response can be shared with the requesting code from the given origins.
Value can be one of the following:
- **string** - Name of origin which will directly assign to Access-Control-Allow-Origin header.
- **boolean** - If set to true, Access-Control-Allow-Origin will be set to `*` (any origins)
- **RegExp** - Pattern to match request's URL, allowed if matched.
- **Function** - Custom logic to allow resource sharing, allow if `true` is returned.
- Expected to have the type of:
```typescript
cors(context: Context) => boolean | void
```
- **Array<string | RegExp | Function>** - iterate through all cases above in order, allowed if any of the values are `true`.
---
### methods
@default `*`
Allowed methods for cross-origin requests by assign `Access-Control-Allow-Methods` header.
Value can be one of the following:
- **undefined | null | ''** - Ignore all methods.
- **\*** - Allows all methods.
- **string** - Expects either a single method or a comma-delimited string
- (eg: `'GET, PUT, POST'`)
- **string[]** - Allow multiple HTTP methods.
- eg: `['GET', 'PUT', 'POST']`
---
### allowedHeaders
@default `*`
Allowed headers for an incoming request by assign `Access-Control-Allow-Headers` header.
Value can be one of the following:
- **string** - Expects either a single header or a comma-delimited string
- eg: `'Content-Type, Authorization'`.
- **string[]** - Allow multiple HTTP headers.
- eg: `['Content-Type', 'Authorization']`
---
### exposeHeaders
@default `*`
Response CORS with specified headers by sssign Access-Control-Expose-Headers header.
Value can be one of the following:
- **string** - Expects either a single header or a comma-delimited string.
- eg: `'Content-Type, X-Powered-By'`.
- **string[]** - Allow multiple HTTP headers.
- eg: `['Content-Type', 'X-Powered-By']`
---
### credentials
@default `true`
The Access-Control-Allow-Credentials response header tells browsers whether to expose the response to the frontend JavaScript code when the request's credentials mode Request.credentials is `include`.
Credentials are cookies, authorization headers, or TLS client certificates by assign `Access-Control-Allow-Credentials` header.
---
### maxAge
@default `5`
Indicates how long the results of a preflight request that is the information contained in the `Access-Control-Allow-Methods` and `Access-Control-Allow-Headers` headers) can be cached.
Assign `Access-Control-Max-Age` header.
---
### preflight
The preflight request is a request sent to check if the CORS protocol is understood and if a server is aware of using specific methods and headers.
Response with **OPTIONS** request with 3 HTTP request headers:
- **Access-Control-Request-Method**
- **Access-Control-Request-Headers**
- **Origin**
This config indicates if the server should respond to preflight requests.
---
## Pattern
Below you can find the common patterns to use the plugin.
## Allow CORS by top-level domain
```typescript twoslash
import { Elysia } from 'elysia'
import { cors } from '@elysiajs/cors'
const app = new Elysia()
.use(
cors({
origin: /.*\.saltyaom\.com$/
})
)
.get('/', () => 'Hi')
.listen(3000)
```
This will allow requests from top-level domains with `saltyaom.com`

# GraphQL Apollo
Plugin for Elysia to use GraphQL Apollo.
## Installation
```bash
bun add graphql @elysiajs/apollo @apollo/server
```
## Basic Usage
```typescript
import { Elysia } from 'elysia'
import { apollo, gql } from '@elysiajs/apollo'
const app = new Elysia()
.use(
apollo({
typeDefs: gql`
type Book {
title: String
author: String
}
type Query {
books: [Book]
}
`,
resolvers: {
Query: {
books: () => {
return [
{
title: 'Elysia',
author: 'saltyAom'
}
]
}
}
}
})
)
.listen(3000)
```
Accessing `/graphql` should show Apollo GraphQL playground work with.
## Context
Because Elysia is based on Web Standard Request and Response which is different from Node's `HttpRequest` and `HttpResponse` that Express uses, results in `req, res` being undefined in context.
Because of this, Elysia replaces both with `context` like route parameters.
```typescript
const app = new Elysia()
.use(
apollo({
typeDefs,
resolvers,
context: async ({ request }) => {
const authorization = request.headers.get('Authorization')
return {
authorization
}
}
})
)
.listen(3000)
```
## Config
This plugin extends Apollo's [ServerRegistration](https://www.apollographql.com/docs/apollo-server/api/apollo-server/#options) (which is `ApolloServer`'s' constructor parameter).
Below are the extended parameters for configuring Apollo Server with Elysia.
### path
@default `"/graphql"`
Path to expose Apollo Server.
---
### enablePlayground
@default `process.env.ENV !== 'production'`

# GraphQL Yoga
This plugin integrates GraphQL yoga with Elysia
## Installation
```bash
bun add @elysiajs/graphql-yoga
```
## Basic Usage
```typescript
import { Elysia } from 'elysia'
import { yoga } from '@elysiajs/graphql-yoga'
const app = new Elysia()
.use(
yoga({
typeDefs: /* GraphQL */ `
type Query {
hi: String
}
`,
resolvers: {
Query: {
hi: () => 'Hello from Elysia'
}
}
})
)
.listen(3000)
```
Accessing `/graphql` in the browser (GET request) would show you a GraphiQL instance for the GraphQL-enabled Elysia server.
optional: you can install a custom version of optional peer dependencies as well:
```bash
bun add graphql graphql-yoga
```
## Resolver
Elysia uses Mobius to infer type from **typeDefs** field automatically, allowing you to get full type-safety and auto-complete when typing **resolver** types.
## Context
You can add custom context to the resolver function by adding **context**
```ts
import { Elysia } from 'elysia'
import { yoga } from '@elysiajs/graphql-yoga'
const app = new Elysia()
.use(
yoga({
typeDefs: /* GraphQL */ `
type Query {
hi: String
}
`,
context: {
name: 'Mobius'
},
// If context is a function on this doesn't present
// for some reason it won't infer context type
useContext(_) {},
resolvers: {
Query: {
hi: async (parent, args, context) => context.name
}
}
})
)
.listen(3000)
```
## Config
This plugin extends [GraphQL Yoga's createYoga options, please refer to the GraphQL Yoga documentation](https://the-guild.dev/graphql/yoga-server/docs) with inlining `schema` config to root.

# HTML
Allows you to use JSX and HTML with proper headers and support.
## Installation
```bash
bun add @elysiajs/html
```
## Basic Usage
```tsx twoslash
import React from 'react'
import { Elysia } from 'elysia'
import { html, Html } from '@elysiajs/html'
new Elysia()
.use(html())
.get(
'/html',
() => `
<html lang='en'>
<head>
<title>Hello World</title>
</head>
<body>
<h1>Hello World</h1>
</body>
</html>`
)
.get('/jsx', () => (
<html lang="en">
<head>
<title>Hello World</title>
</head>
<body>
<h1>Hello World</h1>
</body>
</html>
))
.listen(3000)
```
This plugin will automatically add `Content-Type: text/html; charset=utf8` header to the response, add `<!doctype html>`, and convert it into a Response object.
## JSX
Elysia can use JSX
1. Replace your file that needs to use JSX to end with affix **"x"**:
- .js -> .jsx
- .ts -> .tsx
2. Register the TypeScript type by append the following to **tsconfig.json**:
```jsonc
// tsconfig.json
{
"compilerOptions": {
"jsx": "react",
"jsxFactory": "Html.createElement",
"jsxFragmentFactory": "Html.Fragment"
}
}
```
3. Starts using JSX in your file
```tsx twoslash
import React from 'react'
import { Elysia } from 'elysia'
import { html, Html } from '@elysiajs/html'
new Elysia()
.use(html())
.get('/', () => (
<html lang="en">
<head>
<title>Hello World</title>
</head>
<body>
<h1>Hello World</h1>
</body>
</html>
))
.listen(3000)
```
If the error `Cannot find name 'Html'. Did you mean 'html'?` occurs, this import must be added to the JSX template:
```tsx
import { Html } from '@elysiajs/html'
```
It is important that it is written in uppercase.
## XSS
Elysia HTML is based use of the Kita HTML plugin to detect possible XSS attacks in compile time.
You can use a dedicated `safe` attribute to sanitize user value to prevent XSS vulnerability.
```tsx
import { Elysia, t } from 'elysia'
import { html, Html } from '@elysiajs/html'
new Elysia()
.use(html())
.post(
'/',
({ body }) => (
<html lang="en">
<head>
<title>Hello World</title>
</head>
<body>
<h1 safe>{body}</h1>
</body>
</html>
),
{
body: t.String()
}
)
.listen(3000)
```
However, when are building a large-scale app, it's best to have a type reminder to detect possible XSS vulnerabilities in your codebase.
To add a type-safe reminder, please install:
```sh
bun add @kitajs/ts-html-plugin
```
Then appends the following **tsconfig.json**
```jsonc
// tsconfig.json
{
"compilerOptions": {
"jsx": "react",
"jsxFactory": "Html.createElement",
"jsxFragmentFactory": "Html.Fragment",
"plugins": [{ "name": "@kitajs/ts-html-plugin" }]
}
}
```
## Config
Below is a config which is accepted by the plugin
### contentType
- Type: `string`
- Default: `'text/html; charset=utf8'`
The content-type of the response.
### autoDetect
- Type: `boolean`
- Default: `true`
Whether to automatically detect HTML content and set the content-type.
### autoDoctype
- Type: `boolean | 'full'`
- Default: `true`
Whether to automatically add `<!doctype html>` to a response starting with `<html>`, if not found.
Use `full` to also automatically add doctypes on responses returned without this plugin
```ts
// without the plugin
app.get('/', () => '<html></html>')
// With the plugin
app.get('/', ({ html }) => html('<html></html>'))
```
### isHtml
- Type: `(value: string) => boolean`
- Default: `isHtml` (exported function)
The function is used to detect if a string is a html or not. Default implementation if length is greater than 7, starts with `<` and ends with `>`.
Keep in mind there's no real way to validate HTML, so the default implementation is a best guess.

# JWT Plugin
This plugin adds support for using JWT in Elysia handlers.
## Installation
```bash
bun add @elysiajs/jwt
```
## Basic Usage
```typescript [cookie]
import { Elysia } from 'elysia'
import { jwt } from '@elysiajs/jwt'
const app = new Elysia()
.use(
jwt({
name: 'jwt',
secret: 'Fischl von Luftschloss Narfidort'
})
)
.get('/sign/:name', async ({ jwt, params: { name }, cookie: { auth } }) => {
const value = await jwt.sign({ name })
auth.set({
value,
httpOnly: true,
maxAge: 7 * 86400,
path: '/profile',
})
return `Sign in as ${value}`
})
.get('/profile', async ({ jwt, status, cookie: { auth } }) => {
const profile = await jwt.verify(auth.value)
if (!profile)
return status(401, 'Unauthorized')
return `Hello ${profile.name}`
})
.listen(3000)
```
## Config
This plugin extends config from [jose](https://github.com/panva/jose).
Below is a config that is accepted by the plugin.
### name
Name to register `jwt` function as.
For example, `jwt` function will be registered with a custom name.
```typescript
new Elysia()
.use(
jwt({
name: 'myJWTNamespace',
secret: process.env.JWT_SECRETS!
})
)
.get('/sign/:name', ({ myJWTNamespace, params }) => {
return myJWTNamespace.sign(params)
})
```
Because some might need to use multiple `jwt` with different configs in a single server, explicitly registering the JWT function with a different name is needed.
### secret
The private key to sign JWT payload with.
### schema
Type strict validation for JWT payload.
### alg
@default `HS256`
Signing Algorithm to sign JWT payload with.
Possible properties for jose are:
HS256
HS384
HS512
PS256
PS384
PS512
RS256
RS384
RS512
ES256
ES256K
ES384
ES512
EdDSA
### iss
The issuer claim identifies the principal that issued the JWT as per [RFC7519](https://www.rfc-editor.org/rfc/rfc7519#section-4.1.1)
TLDR; is usually (the domain) name of the signer.
### sub
The subject claim identifies the principal that is the subject of the JWT.
The claims in a JWT are normally statements about the subject as per [RFC7519](https://www.rfc-editor.org/rfc/rfc7519#section-4.1.2)
### aud
The audience claim identifies the recipients that the JWT is intended for.
Each principal intended to process the JWT MUST identify itself with a value in the audience claim as per [RFC7519](https://www.rfc-editor.org/rfc/rfc7519#section-4.1.3)
### jti
JWT ID claim provides a unique identifier for the JWT as per [RFC7519](https://www.rfc-editor.org/rfc/rfc7519#section-4.1.7)
### nbf
The "not before" claim identifies the time before which the JWT must not be accepted for processing as per [RFC7519](https://www.rfc-editor.org/rfc/rfc7519#section-4.1.5)
### exp
The expiration time claim identifies the expiration time on or after which the JWT MUST NOT be accepted for processing as per [RFC7519](https://www.rfc-editor.org/rfc/rfc7519#section-4.1.4)
### iat
The "issued at" claim identifies the time at which the JWT was issued.
This claim can be used to determine the age of the JWT as per [RFC7519](https://www.rfc-editor.org/rfc/rfc7519#section-4.1.6)
### b64
This JWS Extension Header Parameter modifies the JWS Payload representation and the JWS Signing input computation as per [RFC7797](https://www.rfc-editor.org/rfc/rfc7797).
### kid
A hint indicating which key was used to secure the JWS.
This parameter allows originators to explicitly signal a change of key to recipients as per [RFC7515](https://www.rfc-editor.org/rfc/rfc7515#section-4.1.4)
### x5t
(X.509 certificate SHA-1 thumbprint) header parameter is a base64url-encoded SHA-1 digest of the DER encoding of the X.509 certificate [RFC5280](https://www.rfc-editor.org/rfc/rfc5280) corresponding to the key used to digitally sign the JWS as per [RFC7515](https://www.rfc-editor.org/rfc/rfc7515#section-4.1.7)
### x5c
(X.509 certificate chain) header parameter contains the X.509 public key certificate or certificate chain [RFC5280](https://www.rfc-editor.org/rfc/rfc5280) corresponding to the key used to digitally sign the JWS as per [RFC7515](https://www.rfc-editor.org/rfc/rfc7515#section-4.1.6)
### x5u
(X.509 URL) header parameter is a URI [RFC3986](https://www.rfc-editor.org/rfc/rfc3986) that refers to a resource for the X.509 public key certificate or certificate chain [RFC5280] corresponding to the key used to digitally sign the JWS as per [RFC7515](https://www.rfc-editor.org/rfc/rfc7515#section-4.1.5)
### jwk
The "jku" (JWK Set URL) Header Parameter is a URI [RFC3986] that refers to a resource for a set of JSON-encoded public keys, one of which corresponds to the key used to digitally sign the JWS.
The keys MUST be encoded as a JWK Set [JWK] as per [RFC7515](https://www.rfc-editor.org/rfc/rfc7515#section-4.1.2)
### typ
The `typ` (type) Header Parameter is used by JWS applications to declare the media type [IANA.MediaTypes] of this complete JWS.
This is intended for use by the application when more than one kind of object could be present in an application data structure that can contain a JWS as per [RFC7515](https://www.rfc-editor.org/rfc/rfc7515#section-4.1.9)
### ctr
Content-Type parameter is used by JWS applications to declare the media type [IANA.MediaTypes] of the secured content (the payload).
This is intended for use by the application when more than one kind of object could be present in the JWS Payload as per [RFC7515](https://www.rfc-editor.org/rfc/rfc7515#section-4.1.9)
## Handler
Below are the value added to the handler.
### jwt.sign
A dynamic object of collection related to use with JWT registered by the JWT plugin.
Type:
```typescript
sign: (payload: JWTPayloadSpec): Promise<string>
```
`JWTPayloadSpec` accepts the same value as [JWT config](#config)
### jwt.verify
Verify payload with the provided JWT config
Type:
```typescript
verify(payload: string) => Promise<JWTPayloadSpec | false>
```
`JWTPayloadSpec` accepts the same value as [JWT config](#config)
## Pattern
Below you can find the common patterns to use the plugin.
## Set JWT expiration date
By default, the config is passed to `setCookie` and inherits its value.
```typescript
const app = new Elysia()
.use(
jwt({
name: 'jwt',
secret: 'kunikuzushi',
exp: '7d'
})
)
.get('/sign/:name', async ({ jwt, params }) => jwt.sign(params))
```
This will sign JWT with an expiration date of the next 7 days.

# OpenAPI Plugin
## Installation
```bash
bun add @elysiajs/openapi
```
## Basic Usage
```typescript
import { openapi } from '@elysiajs/openapi'
new Elysia()
.use(openapi())
.get('/', () => 'hello')
```
Docs at `/openapi`, spec at `/openapi/json`.
## Detail Object
Extends OpenAPI Operation Object:
```typescript
.get('/', () => 'hello', {
detail: {
title: 'Hello',
description: 'An example route',
summary: 'Short summary',
deprecated: false,
hide: true, // Hide from docs
tags: ['App']
}
})
```
### Documentation Config
```typescript
openapi({
documentation: {
info: {
title: 'API',
version: '1.0.0'
},
tags: [
{ name: 'App', description: 'General' }
],
components: {
securitySchemes: {
bearerAuth: { type: 'http', scheme: 'bearer' }
}
}
}
})
```
### Standard Schema Mapping
```typescript
mapJsonSchema: {
zod: z.toJSONSchema, // Zod 4
valibot: toJsonSchema,
effect: JSONSchema.make
}
```
Zod 3: `zodToJsonSchema` from `zod-to-json-schema`
## OpenAPI Type Gen
Generate docs from types:
```typescript
import { fromTypes } from '@elysiajs/openapi'
export const app = new Elysia()
.use(openapi({
references: fromTypes()
}))
```
### Production
Recommended to generate `.d.ts` file for production when using OpenAPI Type Gen
```typescript
references: fromTypes(
process.env.NODE_ENV === 'production'
? 'dist/index.d.ts'
: 'src/index.ts'
)
```
### Options
```typescript
fromTypes('src/index.ts', {
projectRoot: path.join('..', import.meta.dir),
tsconfigPath: 'tsconfig.dts.json'
})
```
### Caveat: Explicit Types
Use `Prettify` helper to inline when type is not showing:
```typescript
type Prettify<T> = { [K in keyof T]: T[K] } & {}
function getUser(): Prettify<User> { }
```
## Schema Description
```typescript
body: t.Object({
username: t.String(),
password: t.String({
minLength: 8,
description: 'Password (8+ chars)'
})
}, {
description: 'Expected username and password'
}),
detail: {
summary: 'Sign in user',
tags: ['auth']
}
```
## Response Headers
```typescript
import { withHeader } from '@elysiajs/openapi'
response: withHeader(
t.Literal('Hi'),
{ 'x-powered-by': t.Literal('Elysia') }
)
```
Annotation only - doesn't enforce. Set headers manually.
## Tags
Define + assign:
```typescript
.use(openapi({
documentation: {
tags: [
{ name: 'App', description: 'General' },
{ name: 'Auth', description: 'Auth' }
]
}
}))
.get('/', () => 'hello', {
detail: { tags: ['App'] }
})
```
### Instance Tags
```typescript
new Elysia({ tags: ['user'] })
.get('/user', 'user')
```
## Reference Models
Auto-generates schemas:
```typescript
.model({
User: t.Object({
id: t.Number(),
username: t.String()
})
})
.get('/user', () => ({ id: 1, username: 'x' }), {
response: { 200: 'User' },
detail: { tags: ['User'] }
})
```
## Guard
Apply to instance/group:
```typescript
.guard({
detail: {
description: 'Requires auth'
}
})
.get('/user', 'user')
```
## Security
```typescript
.use(openapi({
documentation: {
components: {
securitySchemes: {
bearerAuth: {
type: 'http',
scheme: 'bearer',
bearerFormat: 'JWT'
}
}
}
}
}))
new Elysia({
prefix: '/address',
detail: {
security: [{ bearerAuth: [] }]
}
})
```
Secures all routes under prefix.
## Config
Below is a config which is accepted by the `openapi({})`
### enabled
@default true
Enable/Disable the plugin
### documentation
OpenAPI documentation information
@see https://spec.openapis.org/oas/v3.0.3.html

# OpenTelemetry Plugin - SKILLS.md
## Installation
```bash
bun add @elysiajs/opentelemetry
```
## Basic Usage
```typescript
import { opentelemetry } from '@elysiajs/opentelemetry'
import { BatchSpanProcessor } from '@opentelemetry/sdk-trace-node'
import { OTLPTraceExporter } from '@opentelemetry/exporter-trace-otlp-proto'
new Elysia()
.use(opentelemetry({
spanProcessors: [
new BatchSpanProcessor(new OTLPTraceExporter())
]
}))
```
Auto-collects spans from OpenTelemetry-compatible libraries. Parent/child spans applied automatically.
## Config
Extends OpenTelemetry SDK params:
- `autoDetectResources` (true) - Auto-detect from env
- `contextManager` (AsyncHooksContextManager) - Custom context
- `textMapPropagator` (CompositePropagator) - W3C Trace + Baggage
- `metricReader` - For MeterProvider
- `views` - Histogram bucket config
- `instrumentations` (getNodeAutoInstrumentations()) - Metapackage or individual
- `resource` - Custom resource
- `resourceDetectors` ([envDetector, processDetector, hostDetector]) - Auto-detect needs `autoDetectResources: true`
- `sampler` - Custom sampler (default: sample all)
- `serviceName` - Namespace identifier
- `spanProcessors` - Array for tracer provider
- `traceExporter` - Auto-setup OTLP/http/protobuf with BatchSpanProcessor if not set
- `spanLimits` - Tracing params
### Resource Detectors via Env
```bash
export OTEL_NODE_RESOURCE_DETECTORS="env,host"
# Options: env, host, os, process, serviceinstance, all, none
```
## Export to Backends
Example - Axiom:
```typescript
.use(opentelemetry({
spanProcessors: [
new BatchSpanProcessor(
new OTLPTraceExporter({
url: 'https://api.axiom.co/v1/traces',
headers: {
Authorization: `Bearer ${Bun.env.AXIOM_TOKEN}`,
'X-Axiom-Dataset': Bun.env.AXIOM_DATASET
}
})
)
]
}))
```
## OpenTelemetry SDK
Use SDK normally - runs under Elysia's request span, auto-appears in trace.
## Record Utility
Equivalent to `startActiveSpan` - auto-closes + captures exceptions:
```typescript
import { record } from '@elysiajs/opentelemetry'
.get('', () => {
return record('database.query', () => {
return db.query('SELECT * FROM users')
})
})
```
Label for code shown in trace.
## Function Naming
Elysia reads function names as span names:
```typescript
// ⚠️ Anonymous span
.derive(async ({ cookie: { session } }) => {
return { user: await getProfile(session) }
})
// ✅ Named span: "getProfile"
.derive(async function getProfile({ cookie: { session } }) {
return { user: await getProfile(session) }
})
```
## getCurrentSpan
Get current span outside handler (via AsyncLocalStorage):
```typescript
import { getCurrentSpan } from '@elysiajs/opentelemetry'
function utility() {
const span = getCurrentSpan()
span.setAttributes({ 'custom.attribute': 'value' })
}
```
## setAttributes
Sugar for `getCurrentSpan().setAttributes`:
```typescript
import { setAttributes } from '@elysiajs/opentelemetry'
function utility() {
setAttributes({ 'custom.attribute': 'value' })
}
```
## Instrumentations (Advanced)
SDK must run before importing instrumented module.
### Setup
1. Separate file:
```typescript
// src/instrumentation.ts
import { opentelemetry } from '@elysiajs/opentelemetry'
import { PgInstrumentation } from '@opentelemetry/instrumentation-pg'
export const instrumentation = opentelemetry({
instrumentations: [new PgInstrumentation()]
})
```
2. Apply:
```typescript
// src/index.ts
import { instrumentation } from './instrumentation'
new Elysia().use(instrumentation).listen(3000)
```
3. Preload:
```toml
# bunfig.toml
preload = ["./src/instrumentation.ts"]
```
### Production Deployment (Advanced)
OpenTelemetry monkey-patches `node_modules`. Exclude instrumented libs from bundling:
```bash
bun build --compile --external pg --outfile server src/index.ts
```
Package.json:
```json
{
"dependencies": { "pg": "^8.15.6" },
"devDependencies": {
"@elysiajs/opentelemetry": "^1.2.0",
"@opentelemetry/instrumentation-pg": "^0.52.0"
}
}
```
Production install:
```bash
bun install --production
```
Keeps `node_modules` with instrumented libs at runtime.

# Server Timing Plugin
This plugin adds support for auditing performance bottlenecks with Server Timing API
## Installation
```bash
bun add @elysiajs/server-timing
```
## Basic Usage
```typescript twoslash
import { Elysia } from 'elysia'
import { serverTiming } from '@elysiajs/server-timing'
new Elysia()
.use(serverTiming())
.get('/', () => 'hello')
.listen(3000)
```
Server Timing then will append header 'Server-Timing' with log duration, function name, and detail for each life-cycle function.
To inspect, open browser developer tools > Network > [Request made through Elysia server] > Timing.
Now you can effortlessly audit the performance bottleneck of your server.
## Config
Below is a config which is accepted by the plugin
### enabled
@default `NODE_ENV !== 'production'`
Determine whether or not Server Timing should be enabled
### allow
@default `undefined`
A condition whether server timing should be log
### trace
@default `undefined`
Allow Server Timing to log specified life-cycle events:
Trace accepts objects of the following:
- request: capture duration from request
- parse: capture duration from parse
- transform: capture duration from transform
- beforeHandle: capture duration from beforeHandle
- handle: capture duration from the handle
- afterHandle: capture duration from afterHandle
- total: capture total duration from start to finish
## Pattern
Below you can find the common patterns to use the plugin.
## Allow Condition
You may disable Server Timing on specific routes via `allow` property
```ts twoslash
import { Elysia } from 'elysia'
import { serverTiming } from '@elysiajs/server-timing'
new Elysia()
.use(
serverTiming({
allow: ({ request }) => {
return new URL(request.url).pathname !== '/no-trace'
}
})
)

# Static Plugin
This plugin can serve static files/folders for Elysia Server
## Installation
```bash
bun add @elysiajs/static
```
## Basic Usage
```typescript twoslash
import { Elysia } from 'elysia'
import { staticPlugin } from '@elysiajs/static'
new Elysia()
.use(staticPlugin())
.listen(3000)
```
By default, the static plugin default folder is `public`, and registered with `/public` prefix.
Suppose your project structure is:
```
| - src
| - index.ts
| - public
| - takodachi.png
| - nested
| - takodachi.png
```
The available path will become:
- /public/takodachi.png
- /public/nested/takodachi.png
## Config
Below is a config which is accepted by the plugin
### assets
@default `"public"`
Path to the folder to expose as static
### prefix
@default `"/public"`
Path prefix to register public files
### ignorePatterns
@default `[]`
List of files to ignore from serving as static files
### staticLimit
@default `1024`
By default, the static plugin will register paths to the Router with a static name, if the limits are exceeded, paths will be lazily added to the Router to reduce memory usage.
Tradeoff memory with performance.
### alwaysStatic
@default `false`
If set to true, static files path will be registered to Router skipping the `staticLimits`.
### headers
@default `{}`
Set response headers of files
### indexHTML
@default `false`
If set to true, the `index.html` file from the static directory will be served for any request that is matching neither a route nor any existing static file.
## Pattern
Below you can find the common patterns to use the plugin.
## Single file
Suppose you want to return just a single file, you can use `file` instead of using the static plugin
```typescript
import { Elysia, file } from 'elysia'
new Elysia()
.get('/file', file('public/takodachi.png'))
```

# Fullstack Dev Server
## What It Is
Bun 1.3 Fullstack Dev Server with HMR. React without bundler (no Vite/Webpack).
Example: [elysia-fullstack-example](https://github.com/saltyaom/elysia-fullstack-example)
## Setup
1. Install + use Elysia Static:
```typescript
import { Elysia } from 'elysia'
import { staticPlugin } from '@elysiajs/static'
new Elysia()
.use(await staticPlugin()) // await required for HMR hooks
.listen(3000)
```
2. Create `public/index.html` + `public/index.tsx`:
```html
<!-- public/index.html -->
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Elysia React App</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<div id="root"></div>
<script type="module" src="./index.tsx"></script>
</body>
</html>
```
```tsx
// public/index.tsx
import { useState } from 'react'
import { createRoot } from 'react-dom/client'
function App() {
const [count, setCount] = useState(0)
const increase = () => setCount((c) => c + 1)
return (
<main>
<h2>{count}</h2>
<button onClick={increase}>Increase</button>
</main>
)
}
const root = createRoot(document.getElementById('root')!)
root.render(<App />)
```
3. Enable JSX in `tsconfig.json`:
```json
{
"compilerOptions": {
"jsx": "react-jsx"
}
}
```
4. Navigate to `http://localhost:3000/public`.
Frontend + backend in single project. No bundler. Works with HMR, Tailwind, Tanstack Query, Eden Treaty, path alias.
## Custom Prefix
```typescript
.use(await staticPlugin({ prefix: '/' }))
```
Serves at `/` instead of `/public`.
## Tailwind CSS
1. Install:
```bash
bun add tailwindcss@4
bun add -d bun-plugin-tailwind
```
2. Create `bunfig.toml`:
```toml
[serve.static]
plugins = ["bun-plugin-tailwind"]
```
3. Create `public/global.css`:
```css
@tailwind base;
```
4. Add to HTML or TS:
```html
<link rel="stylesheet" href="tailwindcss">
```
Or:
```tsx
import './global.css'
```
## Path Alias
1. Add to `tsconfig.json`:
```json
{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"@public/*": ["public/*"]
}
}
}
```
2. Use:
```tsx
import '@public/global.css'
```
Works out of box.
## Production Build
```bash
bun build --compile --target bun --outfile server src/index.ts
```
Creates single executable `server`. Include `public` folder when running.

# Cookie
## What It Is
Reactive mutable signal for cookie interaction. Auto-encodes/decodes objects.
## Basic Usage
No get/set - direct value access:
```typescript
import { Elysia } from 'elysia'
new Elysia()
.get('/', ({ cookie: { name } }) => {
// Get
name.value
// Set
name.value = "New Value"
})
```
Auto-encodes/decodes objects. Just works.
## Reactivity
Signal-like approach. Single source of truth. Auto-sets headers, syncs values.
Cookie jar = Proxy object. Extract value always `Cookie<unknown>`, never `undefined`. Access via `.value`.
Iterate over cookie jar → only existing cookies.
## Cookie Attributes
### Direct Property Assignment
```typescript
.get('/', ({ cookie: { name } }) => {
// Get
name.domain
// Set
name.domain = 'millennium.sh'
name.httpOnly = true
})
```
### set - Reset All Properties
```typescript
.get('/', ({ cookie: { name } }) => {
name.set({
domain: 'millennium.sh',
httpOnly: true
})
})
```
Overwrites all properties.
### add - Update Specific Properties
Like `set` but only overwrites defined properties.
## Remove Cookie
```typescript
.get('/', ({ cookie, cookie: { name } }) => {
name.remove()
// or
delete cookie.name
})
```
## Cookie Schema
Strict validation + type inference with `t.Cookie`:
```typescript
import { Elysia, t } from 'elysia'
new Elysia()
.get('/', ({ cookie: { name } }) => {
name.value = {
id: 617,
name: 'Summoning 101'
}
}, {
cookie: t.Cookie({
name: t.Object({
id: t.Numeric(),
name: t.String()
})
})
})
```
### Nullable Cookie
```typescript
cookie: t.Cookie({
name: t.Optional(
t.Object({
id: t.Numeric(),
name: t.String()
})
)
})
```
## Cookie Signature
Cryptographic hash for verification. Prevents malicious modification.
```typescript
new Elysia()
.get('/', ({ cookie: { profile } }) => {
profile.value = { id: 617, name: 'Summoning 101' }
}, {
cookie: t.Cookie({
profile: t.Object({
id: t.Numeric(),
name: t.String()
})
}, {
secrets: 'Fischl von Luftschloss Narfidort',
sign: ['profile']
})
})
```
Auto-signs/unsigns.
### Global Config
```typescript
new Elysia({
cookie: {
secrets: 'Fischl von Luftschloss Narfidort',
sign: ['profile']
}
})
```
## Cookie Rotation
Auto-handles secret rotation. Old signature verification + new signature signing.
```typescript
new Elysia({
cookie: {
secrets: ['Vengeance will be mine', 'Fischl von Luftschloss Narfidort']
}
})
```
Array = key rotation (retire old, replace with new).
## Config
### secrets
Secret key for signing/unsigning. Array = key rotation.
### domain
Domain Set-Cookie attribute. Default: none (current domain only).
### encode
Function to encode value. Default: `encodeURIComponent`.
### expires
Date for Expires attribute. Default: none (non-persistent, deleted on browser exit).
If both `expires` and `maxAge` set, `maxAge` takes precedence (spec-compliant clients).
### httpOnly (false)
HttpOnly attribute. If true, JS can't access via `document.cookie`.
### maxAge (undefined)
Seconds for Max-Age attribute. Rounded down to integer.
If both `expires` and `maxAge` set, `maxAge` takes precedence (spec-compliant clients).
### path
Path attribute. Default: handler path.
### priority
Priority attribute: `low` | `medium` | `high`. Not fully standardized.
### sameSite
SameSite attribute:
- `true` = Strict
- `false` = not set
- `'lax'` = Lax
- `'none'` = None (explicit cross-site)
- `'strict'` = Strict
Not fully standardized.
### secure
Secure attribute. If true, only HTTPS. Clients won't send over HTTP.

# Deployment
## Production Build
### Compile to Binary (Recommended)
```bash
bun build \
--compile \
--minify-whitespace \
--minify-syntax \
--target bun \
--outfile server \
src/index.ts
```
**Benefits:**
- No runtime needed on deployment server
- Smaller memory footprint (2-3x reduction)
- Faster startup
- Single portable executable
**Run the binary:**
```bash
./server
```
### Compile to JavaScript
```bash
bun build \
--minify-whitespace \
--minify-syntax \
--outfile ./dist/index.js \
src/index.ts
```
**Run:**
```bash
NODE_ENV=production bun ./dist/index.js
```
## Docker
### Basic Dockerfile
```dockerfile
FROM oven/bun:1 AS build
WORKDIR /app
# Cache dependencies
COPY package.json bun.lock ./
RUN bun install
COPY ./src ./src
ENV NODE_ENV=production
RUN bun build \
--compile \
--minify-whitespace \
--minify-syntax \
--outfile server \
src/index.ts
FROM gcr.io/distroless/base
WORKDIR /app
COPY --from=build /app/server server
ENV NODE_ENV=production
CMD ["./server"]
EXPOSE 3000
```
### Build and Run
```bash
docker build -t my-elysia-app .
docker run -p 3000:3000 my-elysia-app
```
### With Environment Variables
```dockerfile
FROM gcr.io/distroless/base
WORKDIR /app
COPY --from=build /app/server server
ENV NODE_ENV=production
ENV PORT=3000
ENV DATABASE_URL=""
ENV JWT_SECRET=""
CMD ["./server"]
EXPOSE 3000
```
## Cluster Mode (Multiple CPU Cores)
```typescript
// src/index.ts
import cluster from 'node:cluster'
import os from 'node:os'
import process from 'node:process'
if (cluster.isPrimary) {
for (let i = 0; i < os.availableParallelism(); i++) {
cluster.fork()
}
} else {
await import('./server')
console.log(`Worker ${process.pid} started`)
}
```
```typescript
// src/server.ts
import { Elysia } from 'elysia'
new Elysia()
.get('/', () => 'Hello World!')
.listen(3000)
```
## Environment Variables
### .env File
```env
NODE_ENV=production
PORT=3000
DATABASE_URL=postgresql://user:password@localhost:5432/db
JWT_SECRET=your-secret-key
CORS_ORIGIN=https://example.com
```
### Load in App
```typescript
import { Elysia } from 'elysia'
const app = new Elysia()
.get('/env', () => ({
env: process.env.NODE_ENV,
port: process.env.PORT
}))
.listen(parseInt(process.env.PORT || '3000'))
```
## Platform-Specific Deployments
### Railway
```typescript
// Railway assigns random PORT via env variable
new Elysia()
.get('/', () => 'Hello Railway')
.listen(process.env.PORT ?? 3000)
```
### Vercel
```typescript
// src/index.ts
import { Elysia } from 'elysia'
export default new Elysia()
.get('/', () => 'Hello Vercel')
export const GET = app.fetch
export const POST = app.fetch
```
```json
// vercel.json
{
"$schema": "https://openapi.vercel.sh/vercel.json",
"bunVersion": "1.x"
}
```
### Cloudflare Workers
```typescript
import { Elysia } from 'elysia'
import { CloudflareAdapter } from 'elysia/adapter/cloudflare-worker'
export default new Elysia({
adapter: CloudflareAdapter
})
.get('/', () => 'Hello Cloudflare!')
.compile()
```
```toml
# wrangler.toml
name = "elysia-app"
main = "src/index.ts"
compatibility_date = "2025-06-01"
```
### Node.js Adapter
```typescript
import { Elysia } from 'elysia'
import { node } from '@elysiajs/node'
const app = new Elysia({ adapter: node() })
.get('/', () => 'Hello Node.js')
.listen(3000)
```
## Performance Optimization
### Enable AoT Compilation
```typescript
new Elysia({
aot: true // Ahead-of-time compilation
})
```
### Use Native Static Response
```typescript
new Elysia({
nativeStaticResponse: true
})
.get('/version', 1) // Optimized for Bun.serve.static
```
### Precompile Routes
```typescript
new Elysia({
precompile: true // Compile all routes ahead of time
})
```
## Health Checks
```typescript
new Elysia()
.get('/health', () => ({
status: 'ok',
timestamp: Date.now()
}))
.get('/ready', ({ db }) => {
// Check database connection
const isDbReady = checkDbConnection()
if (!isDbReady) {
return status(503, { status: 'not ready' })
}
return { status: 'ready' }
})
```
## Graceful Shutdown
```typescript
import { Elysia } from 'elysia'
const app = new Elysia()
.get('/', () => 'Hello')
.listen(3000)
process.on('SIGTERM', () => {
console.log('SIGTERM received, shutting down gracefully')
app.stop()
process.exit(0)
})
process.on('SIGINT', () => {
console.log('SIGINT received, shutting down gracefully')
app.stop()
process.exit(0)
})
```
## Monitoring
### OpenTelemetry
```typescript
import { opentelemetry } from '@elysiajs/opentelemetry'
new Elysia()
.use(opentelemetry({
serviceName: 'my-service',
endpoint: 'http://localhost:4318'
}))
```
### Custom Logging
```typescript
.onRequest(({ request }) => {
console.log(`[${new Date().toISOString()}] ${request.method} ${request.url}`)
})
.onAfterResponse(({ request, set }) => {
console.log(`[${new Date().toISOString()}] ${request.method} ${request.url} - ${set.status}`)
})
```
## SSL/TLS (HTTPS)
```typescript
import { Elysia, file } from 'elysia'
new Elysia({
serve: {
tls: {
cert: file('cert.pem'),
key: file('key.pem')
}
}
})
.get('/', () => 'Hello HTTPS')
.listen(3000)
```
## Best Practices
1. **Always compile to binary for production**
- Reduces memory usage
- Smaller deployment size
- No runtime needed
2. **Use environment variables**
- Never hardcode secrets
- Use different configs per environment
3. **Enable health checks**
- Essential for load balancers
- K8s/Docker orchestration
4. **Implement graceful shutdown**
- Handle SIGTERM/SIGINT
- Close connections properly
5. **Use cluster mode**
- Utilize all CPU cores
- Better performance under load
6. **Monitor your app**
- Use OpenTelemetry
- Log requests/responses
- Track errors
## Example Production Setup
```typescript
// src/server.ts
import { Elysia } from 'elysia'
import { cors } from '@elysiajs/cors'
import { opentelemetry } from '@elysiajs/opentelemetry'
export const app = new Elysia({
aot: true,
nativeStaticResponse: true
})
.use(cors({
origin: process.env.CORS_ORIGIN || 'http://localhost:3000'
}))
.use(opentelemetry({
serviceName: 'my-service'
}))
.get('/health', () => ({ status: 'ok' }))
.get('/', () => 'Hello Production')
.listen(parseInt(process.env.PORT || '3000'))
// Graceful shutdown
process.on('SIGTERM', () => {
app.stop()
process.exit(0)
})
```
```typescript
// src/index.ts (cluster)
import cluster from 'node:cluster'
import os from 'node:os'
if (cluster.isPrimary) {
for (let i = 0; i < os.availableParallelism(); i++) {
cluster.fork()
}
} else {
await import('./server')
}
```

# Eden Treaty
e2e type safe RPC client for share type from backend to frontend.
## What It Is
Type-safe object representation for Elysia server. Auto-completion + error handling.
## Installation
```bash
bun add @elysiajs/eden
bun add -d elysia
```
Export Elysia server type:
```typescript
const app = new Elysia()
.get('/', () => 'Hi Elysia')
.get('/id/:id', ({ params: { id } }) => id)
.post('/mirror', ({ body }) => body, {
body: t.Object({
id: t.Number(),
name: t.String()
})
})
.listen(3000)
export type App = typeof app
```
Consume on client side:
```typescript
import { treaty } from '@elysiajs/eden'
import type { App } from './server'
const client = treaty<App>('localhost:3000')
// response: Hi Elysia
const { data: index } = await client.get()
// response: 1895
const { data: id } = await client.id({ id: 1895 }).get()
// response: { id: 1895, name: 'Skadi' }
const { data: nendoroid } = await client.mirror.post({
id: 1895,
name: 'Skadi'
})
```
## Common Errors & Fixes
- **Strict mode**: Enable in tsconfig
- **Version mismatch**: `npm why elysia` - must match server/client
- **TypeScript**: Min 5.0
- **Method chaining**: Required on server
- **Bun types**: `bun add -d @types/bun` if using Bun APIs
- **Path alias**: Must resolve same on frontend/backend
### Monorepo Path Alias
Must resolve to same file on frontend/backend
```json
// tsconfig.json at root
{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"@frontend/*": ["./apps/frontend/src/*"],
"@backend/*": ["./apps/backend/src/*"]
}
}
}
```
## Syntax Mapping
| Path | Method | Treaty |
|----------------|--------|-------------------------------|
| / | GET | `.get()` |
| /hi | GET | `.hi.get()` |
| /deep/nested | POST | `.deep.nested.post()` |
| /item/:name | GET | `.item({ name: 'x' }).get()` |
## Parameters
### With body (POST/PUT/PATCH/DELETE):
```typescript
.user.post(
{ name: 'Elysia' }, // body
{ headers: {}, query: {}, fetch: {} } // optional
)
```
### No body (GET/HEAD):
```typescript
.hello.get({ headers: {}, query: {}, fetch: {} })
```
### Empty body with query/headers:
```typescript
.user.post(null, { query: { name: 'Ely' } })
```
### Fetch options:
```typescript
.hello.get({ fetch: { signal: controller.signal } })
```
### File upload:
```typescript
// Accepts: File | File[] | FileList | Blob
.image.post({
title: 'Title',
image: fileInput.files!
})
```
## Response
```typescript
const { data, error, response, status, headers } = await api.user.post({ name: 'x' })
if (error) {
switch (error.status) {
case 400: throw error.value
default: throw error.value
}
}
// data unwrapped after error handling
return data
```
status >= 300 → `data = null`, `error` has value
## Stream/SSE
Interpreted as `AsyncGenerator`:
```typescript
const { data, error } = await treaty(app).ok.get()
if (error) throw error
for await (const chunk of data) console.log(chunk)
```
## Utility Types
```typescript
import { Treaty } from '@elysiajs/eden'
type UserData = Treaty.Data<typeof api.user.post>
type UserError = Treaty.Error<typeof api.user.post>
```
## WebSocket
```typescript
const chat = api.chat.subscribe()
chat.subscribe((message) => console.log('got', message))
chat.on('open', () => chat.send('hello'))
// Native access: chat.raw
```
`.subscribe()` accepts same params as `get`/`head`

# Lifecycle
Instead of a sequential process, Elysia's request handling is divided into multiple stages called lifecycle events.
It's designed to separate the process into distinct phases based on their responsibility without interfering with each others.
### List of events in order
1. **request** - early, global
2. **parse** - body parsing
3. **transform** / **derive** - mutate context pre validation
4. **beforeHandle** / **resolve** - auth/guard logic
5. **handler** - your business code
6. **afterHandle** - tweak response, set headers
7. **mapResponse** - turn anything into a proper `Response`
8. **onError** - centralized error handling
9. **onAfterResponse** - post response/cleanup tasks
## Request (`onRequest`)
Runs first for every incoming request.
- Ideal for **caching, rate limiting, CORS, adding global headers**.
- If the hook returns a value, the whole lifecycle stops and that value becomes the response.
```ts
new Elysia().onRequest(({ ip, set }) => {
if (blocked(ip)) return (set.status = 429)
})
```
---
## Parse (`onParse`)
_Body parsing stage._
- Handles `text/plain`, `application/json`, `multipart/form-data`, `application/x www-form-urlencoded` by default.
- Use to add **custom parsers** or support extra `Content Type`s.
```ts
new Elysia().onParse(({ request, contentType }) => {
if (contentType === 'application/custom') return request.text()
})
```
---
## Transform (`onTransform`)
_Runs **just before validation**; can mutate the request context._
- Perfect for **type coercion**, trimming strings, or adding temporary fields that validation will use.
```ts
new Elysia().onTransform(({ params }) => {
params.id = Number(params.id)
})
```
---
## Derive
_Runs along with `onTransform` **but before validation**; adds per request values to the context._
- Useful for extracting info from headers, cookies, query, etc., that you want to reuse in handlers.
```ts
new Elysia().derive(({ headers }) => ({
bearer: headers.authorization?.replace(/^Bearer /, '')
}))
```
---
## Before Handle (`onBeforeHandle`)
_Executed after validation, right before the route handler._
- Great for **auth checks, permission gating, custom pre validation logic**.
- Returning a value skips the handler.
```ts
new Elysia().get('/', () => 'hi', {
beforeHandle({ cookie, status }) {
if (!cookie.session) return status(401)
}
})
```
---
## Resolve
_Like `derive` but runs **after validation** along "Before Handle" (so you can rely on validated data)._
- Usually placed inside a `guard` because it isn't available as a local hook.
```ts
new Elysia().guard(
{ headers: t.Object({ authorization: t.String() }) },
(app) =>
app
.resolve(({ headers }) => ({
bearer: headers.authorization.split(' ')[1]
}))
.get('/', ({ bearer }) => bearer)
)
```
---
## After Handle (`onAfterHandle`)
_Runs after the handler finishes._
- Can **modify response headers**, wrap the result in a `Response`, or transform the payload.
- Returning a value **replaces** the handler’s result, but the next `afterHandle` hooks still run.
```ts
new Elysia().get('/', () => '<h1>Hello</h1>', {
afterHandle({ response, set }) {
if (isHtml(response)) {
set.headers['content-type'] = 'text/html; charset=utf-8'
return new Response(response)
}
}
})
```
---
## Map Response (`mapResponse`)
_Runs right after all `afterHandle` hooks; maps **any** value to a Web standard `Response`._
- Ideal for **compression, custom content type mapping, streaming**.
```ts
new Elysia().mapResponse(({ responseValue, set }) => {
const body =
typeof responseValue === 'object'
? JSON.stringify(responseValue)
: String(responseValue ?? '')
set.headers['content-encoding'] = 'gzip'
return new Response(Bun.gzipSync(new TextEncoder().encode(body)), {
headers: {
'Content-Type':
typeof responseValue === 'object'
? 'application/json'
: 'text/plain'
}
})
})
```
---
## On Error (`onError`)
_Caught whenever an error bubbles up from any lifecycle stage._
- Use to **customize error messages**, **handle 404**, **log**, or **retry**.
- Must be registered **before** the routes it should protect.
```ts
new Elysia().onError(({ code, status }) => {
if (code === 'NOT_FOUND') return status(404, '❓ Not found')
return new Response('Oops', { status: 500 })
})
```
---
## After Response (`onAfterResponse`)
_Runs **after** the response has been sent to the client._
- Perfect for **logging, metrics, cleanup**.
```ts
new Elysia().onAfterResponse(() =>
console.log('✅ response sent at', Date.now())
)
```
---
## Hook Types
| Type | Scope | How to add |
| -------------------- | --------------------------------- | --------------------------------------------------------- |
| **Local Hook** | Single route | Inside route options (`afterHandle`, `beforeHandle`, …) |
| **Interceptor Hook** | Whole instance (and later routes) | `.onXxx(cb)` or `.use(plugin)` |
> **Remember:** Hooks only affect routes **defined after** they are registered, except `onRequest` which is global because it runs before route matching.

# Macro
Composable Elysia function for controlling lifecycle/schema/context with full type safety. Available in hook after definition control by key-value label.
## Basic Pattern
```typescript
.macro({
hi: (word: string) => ({
beforeHandle() { console.log(word) }
})
})
.get('/', () => 'hi', { hi: 'Elysia' })
```
## Property Shorthand
Object → function accepting boolean:
```typescript
.macro({
// These equivalent:
isAuth: { resolve: () => ({ user: 'saltyaom' }) },
isAuth(enabled: boolean) { if(enabled) return { resolve() {...} } }
})
```
## Error Handling
Return `status`, don't throw:
```typescript
.macro({
auth: {
resolve({ headers }) {
if(!headers.authorization) return status(401, 'Unauthorized')
return { user: 'SaltyAom' }
}
}
})
```
## Resolve - Add Context Props
```typescript
.macro({
user: (enabled: true) => ({
resolve: () => ({ user: 'Pardofelis' })
})
})
.get('/', ({ user }) => user, { user: true })
```
### Named Macro for Type Inference
TypeScript limitation workaround:
```typescript
.macro('user', { resolve: () => ({ user: 'lilith' }) })
.macro('user2', { user: true, resolve: ({ user }) => {} })
```
## Schema
Auto-validates, infers types, stacks with other schemas:
```typescript
.macro({
withFriends: {
body: t.Object({ friends: t.Tuple([...]) })
}
})
```
Use named single macro for lifecycle type inference within same macro.
## Extension
Stack macros:
```typescript
.macro({
sartre: { body: t.Object({...}) },
fouco: { body: t.Object({...}) },
lilith: { fouco: true, sartre: true, body: t.Object({...}) }
})
```
## Deduplication
Auto-dedupes by property value. Custom seed:
```typescript
.macro({ sartre: (role: string) => ({ seed: role, ... }) })
```
Max stack: 16 (prevents infinite loops)

# Plugins
## Plugin = Decoupled Elysia Instance
```ts
const plugin = new Elysia()
.decorate('plugin', 'hi')
.get('/plugin', ({ plugin }) => plugin)
const app = new Elysia()
.use(plugin) // inherit properties
.get('/', ({ plugin }) => plugin)
```
**Inherits**: state, decorate
**Does NOT inherit**: lifecycle (isolated by default)
## Dependency
Each instance runs independently like microservice. **Must explicitly declare dependencies**.
```ts
const auth = new Elysia()
.decorate('Auth', Auth)
// ❌ Missing dependency
const main = new Elysia()
.get('/', ({ Auth }) => Auth.getProfile())
// ✅ Declare dependency
const main = new Elysia()
.use(auth) // required for Auth
.get('/', ({ Auth }) => Auth.getProfile())
```
## Deduplication
**Every plugin re-executes by default**. Use `name` + optional `seed` to deduplicate:
```ts
const ip = new Elysia({ name: 'ip' }) // unique identifier
.derive({ as: 'global' }, ({ server, request }) => ({
ip: server?.requestIP(request)
}))
const router1 = new Elysia().use(ip)
const router2 = new Elysia().use(ip)
const server = new Elysia().use(router1).use(router2)
// `ip` only executes once due to deduplication
```
## Global vs Explicit Dependency
**Global plugin** (rare, apply everywhere):
- Doesn't add types - cors, compress, helmet
- Global lifecycle no instance controls - tracing, logging
- Examples: OpenAPI docs, OpenTelemetry, logging
**Explicit dependency** (default, recommended):
- Adds types - macro, state, model
- Business logic instances interact with - Auth, DB
- Examples: state management, ORM, auth, features
## Scope
**Lifecycle isolated by default**. Must specify scope to export.
```ts
// ❌ NOT inherited by app
const profile = new Elysia()
.onBeforeHandle(({ cookie }) => throwIfNotSignIn(cookie))
.get('/profile', () => 'Hi')
const app = new Elysia()
.use(profile)
.patch('/rename', ({ body }) => updateProfile(body)) // No sign-in check
// ✅ Exported to app
const profile = new Elysia()
.onBeforeHandle({ as: 'global' }, ({ cookie }) => throwIfNotSignIn(cookie))
.get('/profile', () => 'Hi')
```
## Scope Levels
1. **local** (default) - current + descendants only
2. **scoped** - parent + current + descendants
3. **global** - all instances (all parents, current, descendants)
Example with `.onBeforeHandle({ as: 'local' }, ...)`:
| type | child | current | parent | main |
|------|-------|---------|--------|------|
| local | ✅ | ✅ | ❌ | ❌ |
| scoped | ✅ | ✅ | ✅ | ❌ |
| global | ✅ | ✅ | ✅ | ✅ |
## Config
```ts
// Instance factory with config
const version = (v = 1) => new Elysia()
.get('/version', v)
const app = new Elysia()
.use(version(1))
```
## Functional Callback (not recommended)
```ts
// Harder to handle scope/encapsulation
const plugin = (app: Elysia) => app
.state('counter', 0)
.get('/plugin', () => 'Hi')
// Prefer new instance (better type inference, no perf diff)
```
## Guard (Apply to Multiple Routes)
```ts
.guard(
{ body: t.Object({ username: t.String(), password: t.String() }) },
(app) =>
app.post('/sign-up', ({ body }) => signUp(body))
.post('/sign-in', ({ body }) => signIn(body))
)
```
**Grouped guard** (merge group + guard):
```ts
.group(
'/v1',
{ body: t.Literal('Rikuhachima Aru') }, // guard here
(app) => app.post('/student', ({ body }) => body)
)
```
## Scope Casting
**3 methods to apply hook to parent**:
1. **Inline as** (single hook):
```ts
.derive({ as: 'scoped' }, () => ({ hi: 'ok' }))
```
2. **Guard as** (multiple hooks, no derive/resolve):
```ts
.guard({
as: 'scoped',
response: t.String(),
beforeHandle() { console.log('ok') }
})
```
3. **Instance as** (all hooks + schema):
```ts
const plugin = new Elysia()
.derive(() => ({ hi: 'ok' }))
.get('/child', ({ hi }) => hi)
.as('scoped') // lift scope up
```
`.as()` lifts scope: local → scoped → global
## Lazy Load
**Deferred module** (async plugin, non-blocking startup):
```ts
// plugin.ts
export const loadStatic = async (app: Elysia) => {
const files = await loadAllFiles()
files.forEach((asset) => app.get(asset, file(asset)))
return app
}
// main.ts
const app = new Elysia().use(loadStatic)
```
**Lazy-load module** (dynamic import):
```ts
const app = new Elysia()
.use(import('./plugin')) // loaded after startup
```
**Testing** (wait for modules):
```ts
await app.modules // ensure all deferred/lazy modules loaded
```
## Notes
[Inference] Based on docs patterns:
- Use inline values for static resources (performance optimization)
- Group routes by prefix for organization
- Extend context minimally (separation of concerns)
- Use `status()` over `set.status` for type safety
- Prefer `resolve()` over `derive()` when type integrity matters
- Plugins isolated by default (must declare scope explicitly)
- Use `name` for deduplication when plugin used multiple times
- Prefer explicit dependency over global (better modularity/tracking)

# ElysiaJS: Routing, Handlers & Context
## Routing
### Path Types
```ts
new Elysia()
.get('/static', 'static path') // exact match
.get('/id/:id', 'dynamic path') // captures segment
.get('/id/*', 'wildcard path') // captures rest
```
**Path Priority**: static > dynamic > wildcard
### Dynamic Paths
```ts
new Elysia()
.get('/id/:id', ({ params: { id } }) => id)
.get('/id/:id/:name', ({ params: { id, name } }) => id + ' ' + name)
```
**Optional params**: `.get('/id/:id?', ...)`
### HTTP Verbs
- `.get()` - retrieve data
- `.post()` - submit/create
- `.put()` - replace
- `.patch()` - partial update
- `.delete()` - remove
- `.all()` - any method
- `.route(method, path, handler)` - custom verb
### Grouping Routes
```ts
new Elysia()
.group('/user', { body: t.Literal('auth') }, (app) =>
app.post('/sign-in', ...)
.post('/sign-up', ...)
)
// Or use prefix in constructor
new Elysia({ prefix: '/user' })
.post('/sign-in', ...)
```
## Handlers
### Handler = function accepting HTTP request, returning response
```ts
// Inline value (compiled ahead, optimized)
.get('/', 'Hello Elysia')
.get('/video', file('video.mp4'))
// Function handler
.get('/', () => 'hello')
.get('/', ({ params, query, body }) => {...})
```
### Context Properties
- `body` - HTTP message/form/file
- `query` - query string as object
- `params` - path parameters
- `headers` - HTTP headers
- `cookie` - mutable signal for cookies
- `store` - global mutable state
- `request` - Web Standard Request
- `server` - Bun server instance
- `path` - request pathname
### Context Utilities
```ts
import { redirect, form } from 'elysia'
new Elysia().get('/', ({ status, set, form }) => {
// Status code (type-safe)
status(418, "I'm a teapot")
// Set response props
set.headers['x-custom'] = 'value'
set.status = 418 // legacy, no type inference
// Redirect
return redirect('https://...', 302)
// Cookies (mutable signal, no get/set)
cookie.name.value // get
cookie.name.value = 'new' // set
// FormData response
return form({ name: 'Party', images: [file('a.jpg')] })
// Single file
return file('document.pdf')
})
```
### Streaming
```ts
new Elysia()
.get('/stream', function* () {
yield 1
yield 2
yield 3
})
// Server-Sent Events
.get('/sse', function* () {
yield sse('hello')
yield sse({ event: 'msg', data: {...} })
})
```
**Note**: Headers only settable before first yield
**Conditional stream**: returning without yield converts to normal response
## Context Extension
[Inference] Extend when property is:
- Global mutable (use `state`)
- Request/response related (use `decorate`)
- Derived from existing props (use `derive`/`resolve`)
### state() - Global Mutable
```ts
new Elysia()
`.state('version', 1)
.get('/', ({ store: { version } }) => version)
// Multiple
.state({ counter: 0, visits: 0 })
// Remap (create new from existing)
.state(({ version, ...store }) => ({
...store,
apiVersion: version
}))
````
**Gotcha**: Use reference not value
```ts
new Elysia()
// ✅ Correct
.get('/', ({ store }) => store.counter++)
// ❌ Wrong - loses reference
.get('/', ({ store: { counter } }) => counter++)
```
### decorate() - Additional Context Props
```ts
new Elysia()
.decorate('logger', new Logger())
.get('/', ({ logger }) => logger.log('hi'))
// Multiple
.decorate({ logger: new Logger(), db: connection })
```
**When**: constant/readonly values, classes with internal state, singletons
### derive() - Create from Existing (Transform Lifecycle)
```ts
new Elysia()
.derive(({ headers }) => ({
bearer: headers.authorization?.startsWith('Bearer ')
? headers.authorization.slice(7)
: null
}))
.get('/', ({ bearer }) => bearer)
```
**Timing**: runs at transform (before validation)
**Type safety**: request props typed as `unknown`
### resolve() - Type-Safe Derive (beforeHandle Lifecycle)
```ts
new Elysia()
.guard({
headers: t.Object({
bearer: t.String({ pattern: '^Bearer .+$' })
})
})
.resolve(({ headers }) => ({
bearer: headers.bearer.slice(7) // typed correctly
}))
```
**Timing**: runs at beforeHandle (after validation)
**Type safety**: request props fully typed
### Error from derive/resolve
```ts
new Elysia()
.derive(({ headers, status }) => {
if (!headers.authorization) return status(400)
return { bearer: ... }
})
```
Returns early if error returned
## Patterns
### Affix (Bulk Remap)
```ts
const plugin = new Elysia({ name: 'setup' }).decorate({
argon: 'a',
boron: 'b'
})
new Elysia()
.use(plugin)
.prefix('decorator', 'setup') // setupArgon, setupBoron
.prefix('all', 'setup') // remap everything
```
### Assignment Patterns
1. **key-value**: `.state('key', value)`
2. **object**: `.state({ k1: v1, k2: v2 })`
3. **remap**: `.state(({old}) => ({new}))`
## Testing
```ts
const app = new Elysia().get('/', 'hi')
// Programmatic test
app.handle(new Request('http://localhost/'))
```
## To Throw or Return
Most of an error handling in Elysia can be done by throwing an error and will be handle in `onError`.
But for `status` it can be a little bit confusing, since it can be used both as a return value or throw an error.
It could either be **return** or **throw** based on your specific needs.
- If an `status` is **throw**, it will be caught by `onError` middleware.
- If an `status` is **return**, it will be **NOT** caught by `onError` middleware.
See the following code:
```typescript
import { Elysia, file } from 'elysia'
new Elysia()
.onError(({ code, error, path }) => {
if (code === 418) return 'caught'
})
.get('/throw', ({ status }) => {
// This will be caught by onError
throw status(418)
})
.get('/return', ({ status }) => {
// This will NOT be caught by onError
return status(418)
})
```
## To Throw or Return
Elysia provide a `status` function for returning HTTP status code, prefers over `set.status`.
`status` can be import from Elysia but preferably extract from route handler Context for type safety.
```ts
import { Elysia, status } from 'elysia'
function doThing() {
if (Math.random() > 0.33) return status(418, "I'm a teapot")
}
new Elysia().get('/', ({ status }) => {
if (Math.random() > 0.33) return status(418)
return 'ok'
})
```
Error Handling in Elysia can be done by throwing an error and will be handle in `onError`.
Status could either be **return** or **throw** based on your specific needs.
- If an `status` is **throw**, it will be caught by `onError` middleware.
- If an `status` is **return**, it will be **NOT** caught by `onError` middleware.
See the following code:
```typescript
import { Elysia, file } from 'elysia'
new Elysia()
.onError(({ code, error, path }) => {
if (code === 418) return 'caught'
})
.get('/throw', ({ status }) => {
// This will be caught by onError
throw status(418)
})
.get('/return', ({ status }) => {
// This will NOT be caught by onError
return status(418)
})
```
## Notes
[Inference] Based on docs patterns:
- Use inline values for static resources (performance optimization)
- Group routes by prefix for organization
- Extend context minimally (separation of concerns)
- Use `status()` over `set.status` for type safety
- Prefer `resolve()` over `derive()` when type integrity matters

# Validation Schema - SKILLS.md
## What It Is
Runtime validation + type inference + OpenAPI schema from single source. TypeBox-based with Standard Schema support.
## Basic Usage
```typescript
import { Elysia, t } from 'elysia'
new Elysia()
.get('/id/:id', ({ params: { id } }) => id, {
params: t.Object({ id: t.Number({ minimum: 1 }) }),
response: {
200: t.Number(),
404: t.Literal('Not Found')
}
})
```
## Schema Types
Third parameter of HTTP method:
- **body** - HTTP message
- **query** - URL query params
- **params** - Path params
- **headers** - Request headers
- **cookie** - Request cookies
- **response** - Response (per status)
## Standard Schema Support
Use Zod, Valibot, ArkType, Effect, Yup, Joi:
```typescript
import { z } from 'zod'
import * as v from 'valibot'
.get('/', ({ params, query }) => params.id, {
params: z.object({ id: z.coerce.number() }),
query: v.object({ name: v.literal('Lilith') })
})
```
Mix validators in same handler.
## Body
```typescript
body: t.Object({ name: t.String() })
```
GET/HEAD: body-parser disabled by default (RFC2616).
### File Upload
```typescript
body: t.Object({
file: t.File({ format: 'image/*' }),
multipleFiles: t.Files()
})
// Auto-assumes multipart/form-data
```
### File (Standard Schema)
```typescript
import { fileType } from 'elysia'
body: z.object({
file: z.file().refine((file) => fileType(file, 'image/jpeg'))
})
```
Use `fileType` for security (validates magic number, not just MIME).
## Query
```typescript
query: t.Object({ name: t.String() })
// /?name=Elysia
```
Auto-coerces to specified type.
### Arrays
```typescript
query: t.Object({ name: t.Array(t.String()) })
```
Formats supported:
- **nuqs**: `?name=a,b,c` (comma delimiter)
- **HTML form**: `?name=a&name=b&name=c` (multiple keys)
## Params
```typescript
params: t.Object({ id: t.Number() })
// /id/1
```
Auto-inferred as string if schema not provided.
## Headers
```typescript
headers: t.Object({ authorization: t.String() })
```
`additionalProperties: true` by default. Always lowercase keys.
## Cookie
```typescript
cookie: t.Cookie({
name: t.String()
}, {
secure: true,
httpOnly: true
})
```
Or use `t.Object`. `additionalProperties: true` by default.
## Response
```typescript
response: t.Object({ name: t.String() })
```
### Per Status
```typescript
response: {
200: t.Object({ name: t.String() }),
400: t.Object({ error: t.String() })
}
```
## Error Handling
### Inline Error Property
```typescript
body: t.Object({
x: t.Number({ error: 'x must be number' })
})
```
Or function:
```typescript
x: t.Number({
error({ errors, type, validation, value }) {
return 'Expected x to be number'
}
})
```
### onError Hook
```typescript
.onError(({ code, error }) => {
if (code === 'VALIDATION')
return error.message // or error.all[0].message
})
```
`error.all` - list all error causes. `error.all.find(x => x.path === '/name')` - find specific field.
## Reference Models
Name + reuse models:
```typescript
.model({
sign: t.Object({
username: t.String(),
password: t.String()
})
})
.post('/sign-in', ({ body }) => body, {
body: 'sign',
response: 'sign'
})
```
Extract to plugin:
```typescript
// auth.model.ts
export const authModel = new Elysia().model({ sign: t.Object({...}) })
// main.ts
new Elysia().use(authModel).post('/', ..., { body: 'sign' })
```
### Naming Convention
Prevent duplicates with namespaces:
```typescript
.model({
'auth.admin': t.Object({...}),
'auth.user': t.Object({...})
})
```
Or use `prefix` / `suffix` to rename models in current instance
```typescript
.model({ sign: t.Object({...}) })
.prefix('model', 'auth')
.post('/', () => '', {
body: 'auth.User'
})
```
Models with `prefix` will be capitalized.
## TypeScript Types
```typescript
const MyType = t.Object({ hello: t.Literal('Elysia') })
type MyType = typeof MyType.static
```
Single schema → runtime validation + coercion + TypeScript type + OpenAPI.
## Guard
Apply schema to multiple handlers. Affects all handlers after definition.
### Basic Usage
```typescript
import { Elysia, t } from 'elysia'
new Elysia()
.get('/none', ({ query }) => 'hi')
.guard({
query: t.Object({
name: t.String()
})
})
.get('/query', ({ query }) => query)
.listen(3000)
```
Ensures `query.name` string required for all handlers after guard.
### Behavior
| Path | Response |
|---------------|----------|
| /none | hi |
| /none?name=a | hi |
| /query | error |
| /query?name=a | a |
### Precedence
- Multiple global schemas: latest wins
- Global vs local: local wins
### Schema Types
1. override (default)
Latest schema overrides collided schema.
```typescript
.guard({ query: t.Object({ name: t.String() }) })
.guard({ query: t.Object({ id: t.Number() }) })
// Only id required, name overridden
```
2. standalone
Both schemas run independently. Both validated.
```typescript
.guard({ query: t.Object({ name: t.String() }) }, { type: 'standalone' })
.guard({ query: t.Object({ id: t.Number() }) }, { type: 'standalone' })
// Both name AND id required
```
# Typebox Validation (Elysia.t)
Elysia.t = TypeBox with server-side pre-configuration + HTTP-specific types
**TypeBox API mirrors TypeScript syntax** but provides runtime validation
## Basic Types
| TypeBox | TypeScript | Example Value |
|---------|------------|---------------|
| `t.String()` | `string` | `"hello"` |
| `t.Number()` | `number` | `42` |
| `t.Boolean()` | `boolean` | `true` |
| `t.Array(t.Number())` | `number[]` | `[1, 2, 3]` |
| `t.Object({ x: t.Number() })` | `{ x: number }` | `{ x: 10 }` |
| `t.Null()` | `null` | `null` |
| `t.Literal(42)` | `42` | `42` |
## Attributes (JSON Schema 7)
```ts
// Email format
t.String({ format: 'email' })
// Number constraints
t.Number({ minimum: 10, maximum: 100 })
// Array constraints
t.Array(t.Number(), {
minItems: 1, // min items
maxItems: 5 // max items
})
// Object - allow extra properties
t.Object(
{ x: t.Number() },
{ additionalProperties: true } // default: false
)
```
## Common Patterns
### Union (Multiple Types)
```ts
t.Union([t.String(), t.Number()])
// type: string | number
// values: "Hello" or 123
```
### Optional (Field Optional)
```ts
t.Object({
x: t.Number(),
y: t.Optional(t.Number()) // can be undefined
})
// type: { x: number, y?: number }
// value: { x: 123 } or { x: 123, y: 456 }
```
### Partial (All Fields Optional)
```ts
t.Partial(t.Object({
x: t.Number(),
y: t.Number()
}))
// type: { x?: number, y?: number }
// value: {} or { y: 123 } or { x: 1, y: 2 }
```
## Elysia-Specific Types
### UnionEnum (One of Values)
```ts
t.UnionEnum(['rapi', 'anis', 1, true, false])
```
### File (Single File Upload)
```ts
t.File({
type: 'image', // or ['image', 'video']
minSize: '1k', // 1024 bytes
maxSize: '5m' // 5242880 bytes
})
```
**File unit suffixes**:
- `m` = MegaByte (1048576 bytes)
- `k` = KiloByte (1024 bytes)
### Files (Multiple Files)
```ts
t.Files() // extends File + array
```
### Cookie (Cookie Jar)
```ts
t.Cookie({
name: t.String()
}, {
secrets: 'secret-key' // or ['key1', 'key2'] for rotation
})
```
### Nullable (Allow null)
```ts
t.Nullable(t.String())
// type: string | null
```
### MaybeEmpty (Allow null + undefined)
```ts
t.MaybeEmpty(t.String())
// type: string | null | undefined
```
### Form (FormData Validation)
```ts
t.Form({
someValue: t.File()
})
// Syntax sugar for t.Object with FormData support
```
### UInt8Array (Buffer → Uint8Array)
```ts
t.UInt8Array()
// For binary file uploads with arrayBuffer parser
```
### ArrayBuffer (Buffer → ArrayBuffer)
```ts
t.ArrayBuffer()
// For binary file uploads with arrayBuffer parser
```
### ObjectString (String → Object)
```ts
t.ObjectString()
// Accepts: '{"x":1}' → parses to { x: 1 }
// Use in: query string, headers, FormData
```
### BooleanString (String → Boolean)
```ts
t.BooleanString()
// Accepts: 'true'/'false' → parses to boolean
// Use in: query string, headers, FormData
```
### Numeric (String/Number → Number)
```ts
t.Numeric()
// Accepts: '123' or 123 → transforms to 123
// Use in: path params, query string
```
## Elysia Behavior Differences from TypeBox
### 1. Optional Behavior
In Elysia, `t.Optional` makes **entire route parameter** optional (not object field):
```ts
.get('/optional', ({ query }) => query, {
query: t.Optional( // makes query itself optional
t.Object({ name: t.String() })
)
})
```
**Different from TypeBox**: TypeBox uses Optional for object fields only
### 2. Number → Numeric Auto-Conversion
**Route schema only** (not nested objects):
```ts
.get('/:id', ({ id }) => id, {
params: t.Object({
id: t.Number() // ✅ Auto-converts to t.Numeric()
}),
body: t.Object({
id: t.Number() // ❌ NOT converted (stays t.Number())
})
})
// Outside route schema
t.Number() // ❌ NOT converted
```
**Why**: HTTP headers/query/params always strings. Auto-conversion parses numeric strings.
### 3. Boolean → BooleanString Auto-Conversion
Same as Number → Numeric:
```ts
.get('/:active', ({ active }) => active, {
params: t.Object({
active: t.Boolean() // ✅ Auto-converts to t.BooleanString()
}),
body: t.Object({
active: t.Boolean() // ❌ NOT converted
})
})
```
## Usage Pattern
```ts
import { Elysia, t } from 'elysia'
new Elysia()
.post('/', ({ body }) => `Hello ${body}`, {
body: t.String() // validates body is string
})
.listen(3000)
```
**Validation flow**:
1. Request arrives
2. Schema validates against HTTP body/params/query/headers
3. If valid → handler executes
4. If invalid → Error Life Cycle
## Notes
[Inference] Based on docs:
- TypeBox mirrors TypeScript but adds runtime validation
- Elysia.t extends TypeBox with HTTP-specific types
- Auto-conversion (Number→Numeric, Boolean→BooleanString) only for route schemas
- Use `t.Optional` for optional route params (different from TypeBox behavior)
- File validation supports unit suffixes ('1k', '5m')
- ObjectString/BooleanString for parsing strings in query/headers
- Cookie supports key rotation with array of secrets

description: Design and build modern UI components and pages using shadcn/ui. Creates clean, accessible interfaces with Tailwind CSS following shadcn principles. Use when building UI components, pages, forms, dashboards, or any interface work.
---
# Shadcn UI Designer
Build production-ready UI components using shadcn/ui principles: minimal, accessible, composable, and beautiful by default.
## Core Philosophy
**Design modern, minimal interfaces** with:
- Clean typography (Inter/system fonts, 2-3 weights max)
- Ample whitespace (4px-based spacing: p-1 through p-8)
- Subtle shadows (shadow-sm/md/lg only)
- Accessible contrast (WCAG AA minimum)
- Smooth micro-interactions (200-300ms transitions)
- Professional neutrals (slate/zinc scale) with subtle accents
**Build composable components** that work together seamlessly.
## Quick Start Pattern
```tsx
import { Card, CardHeader, CardTitle, CardContent } from "@/components/ui/card"
import { Button } from "@/components/ui/button"
export function MyComponent() {
return (
<div className="container mx-auto p-6 space-y-6">
<div className="space-y-2">
<h1 className="text-2xl font-semibold">Title</h1>
<p className="text-sm text-muted-foreground">Description</p>
</div>
<Card className="shadow-sm">
<CardHeader>
<CardTitle>Section</CardTitle>
</CardHeader>
<CardContent className="space-y-4">
{/* Content here */}
</CardContent>
</Card>
</div>
)
}
```
## Design System Rules
### Typography
- **Hierarchy**: `text-2xl` (headings) → `text-base` (body) → `text-sm` (secondary)
- **Weights**: `font-semibold` (600) for emphasis, `font-medium` (500) for labels, `font-normal` (400) for body
- **Colors**: `text-foreground` (primary), `text-muted-foreground` (secondary)
```tsx
<h1 className="text-2xl font-semibold">Page Title</h1>
<p className="text-muted-foreground">Supporting text</p>
```
### Spacing
Use consistent spacing scale:
- **Micro**: `space-y-2` (8px) - within sections
- **Small**: `space-y-4` (16px) - between elements
- **Medium**: `space-y-6` (24px) - between sections
- **Large**: `space-y-8` (32px) - major divisions
```tsx
<div className="container mx-auto p-6 space-y-6">
<section className="space-y-4">
<div className="space-y-2">
{/* Related elements */}
</div>
</section>
</div>
```
### Colors
Use semantic color tokens:
- **Background**: `bg-background`, `bg-card`, `bg-muted`
- **Foreground**: `text-foreground`, `text-muted-foreground`
- **Borders**: `border-border`, `border-input`
- **Primary**: `bg-primary`, `text-primary-foreground`
- **Destructive**: `bg-destructive`, `text-destructive-foreground`
```tsx
<Card className="bg-card text-card-foreground border-border">
<Button className="bg-primary text-primary-foreground">
Primary Action
</Button>
<div className="bg-muted/50 text-muted-foreground">
Subtle highlight
</div>
</Card>
```
### Shadows & Elevation
Three levels only:
- `shadow-sm`: Cards, raised sections (0 1px 2px)
- `shadow-md`: Dropdowns, popovers (0 4px 6px)
- `shadow-lg`: Modals, dialogs (0 10px 15px)
```tsx
<Card className="shadow-sm hover:shadow-md transition-shadow" />
```
### Animations
- **Duration**: 200-300ms
- **Easing**: ease-in-out
- **Use cases**: Hover states, loading states, reveals
```tsx
<Button className="transition-colors duration-200 hover:bg-primary/90">
<Card className="transition-all duration-200 hover:shadow-md hover:scale-[1.02]">
```
### Accessibility
Always include:
- Semantic HTML (`<main>`, `<nav>`, `<article>`)
- ARIA labels on icons/actions
- Focus states (`:focus-visible:ring-2`)
- Keyboard navigation
- WCAG AA contrast (4.5:1 minimum)
```tsx
<button
aria-label="Close dialog"
className="focus-visible:ring-2 focus-visible:ring-primary focus-visible:ring-offset-2"
>
<X className="h-4 w-4" />
</button>
```
## Component Patterns
### Dashboard Cards
```tsx
<div className="grid gap-4 md:grid-cols-2 lg:grid-cols-4">
{stats.map(stat => (
<Card key={stat.id} className="shadow-sm">
<CardHeader className="flex flex-row items-center justify-between pb-2">
<CardTitle className="text-sm font-medium">
{stat.label}
</CardTitle>
{stat.icon}
</CardHeader>
<CardContent>
<div className="text-2xl font-bold">{stat.value}</div>
<p className="text-xs text-muted-foreground">
{stat.change}
</p>
</CardContent>
</Card>
))}
</div>
```
### Forms
```tsx
<form className="space-y-6">
<div className="space-y-4">
<div className="space-y-2">
<Label htmlFor="name">Full Name</Label>
<Input
id="name"
placeholder="Enter your name"
className="max-w-md"
/>
</div>
<div className="space-y-2">
<Label htmlFor="email">Email</Label>
<Input
id="email"
type="email"
placeholder="name@example.com"
className="max-w-md"
/>
</div>
</div>
<div className="flex gap-3">
<Button type="submit">Submit</Button>
<Button type="button" variant="outline">Cancel</Button>
</div>
</form>
```
### Data Tables
```tsx
<Card className="shadow-sm">
<CardHeader>
<CardTitle>Recent Orders</CardTitle>
</CardHeader>
<CardContent>
<Table>
<TableHeader>
<TableRow>
<TableHead>Order</TableHead>
<TableHead>Customer</TableHead>
<TableHead>Status</TableHead>
<TableHead className="text-right">Amount</TableHead>
</TableRow>
</TableHeader>
<TableBody>
{orders.map(order => (
<TableRow
key={order.id}
className="hover:bg-muted/50 transition-colors"
>
<TableCell className="font-medium">{order.id}</TableCell>
<TableCell>{order.customer}</TableCell>
<TableCell>
<Badge variant={order.statusVariant}>
{order.status}
</Badge>
</TableCell>
<TableCell className="text-right">
{order.amount}
</TableCell>
</TableRow>
))}
</TableBody>
</Table>
</CardContent>
</Card>
```
### Modals/Dialogs
```tsx
<Dialog>
<DialogTrigger asChild>
<Button>Open Dialog</Button>
</DialogTrigger>
<DialogContent className="sm:max-w-[425px]">
<DialogHeader>
<DialogTitle>Edit Profile</DialogTitle>
<DialogDescription>
Make changes to your profile here. Click save when done.
</DialogDescription>
</DialogHeader>
<div className="space-y-4 py-4">
{/* Form fields */}
</div>
<DialogFooter>
<Button type="submit">Save changes</Button>
</DialogFooter>
</DialogContent>
</Dialog>
```
### Loading States
```tsx
// Skeleton loading
<Card className="shadow-sm">
<CardHeader>
<Skeleton className="h-4 w-[200px]" />
</CardHeader>
<CardContent className="space-y-3">
<Skeleton className="h-4 w-full" />
<Skeleton className="h-4 w-[80%]" />
</CardContent>
</Card>
// Loading button
<Button disabled>
<Loader2 className="mr-2 h-4 w-4 animate-spin" />
Please wait
</Button>
```
### Empty States
```tsx
<Card className="shadow-sm">
<CardContent className="flex flex-col items-center justify-center py-12 space-y-3">
<div className="p-4 bg-muted rounded-full">
<FileX className="h-8 w-8 text-muted-foreground" />
</div>
<div className="text-center space-y-1">
<h3 className="font-semibold">No results found</h3>
<p className="text-sm text-muted-foreground">
Try adjusting your search
</p>
</div>
<Button variant="outline" size="sm">
Clear filters
</Button>
</CardContent>
</Card>
```
## Layout Patterns
### Container Widths
```tsx
// Full width with constraints
<div className="container mx-auto px-4 max-w-7xl">
// Content-focused (prose)
<div className="container mx-auto px-4 max-w-3xl">
// Form-focused
<div className="container mx-auto px-4 max-w-2xl">
```
### Responsive Grids
```tsx
// Dashboard grid
<div className="grid gap-4 md:grid-cols-2 lg:grid-cols-3 xl:grid-cols-4">
// Content + sidebar
<div className="grid gap-6 lg:grid-cols-[1fr_300px]">
<main>{/* Content */}</main>
<aside>{/* Sidebar */}</aside>
</div>
// Two column split
<div className="grid gap-6 md:grid-cols-2">
```
### Navigation
```tsx
<header className="border-b border-border">
<div className="container mx-auto flex h-16 items-center justify-between px-4">
<div className="flex items-center gap-6">
<Logo />
<nav className="hidden md:flex gap-6">
<a href="#" className="text-sm font-medium transition-colors hover:text-primary">
Dashboard
</a>
<a href="#" className="text-sm font-medium text-muted-foreground transition-colors hover:text-foreground">
Projects
</a>
</nav>
</div>
<div className="flex items-center gap-4">
<Button variant="ghost" size="sm">
<Bell className="h-4 w-4" />
</Button>
<Avatar>
<AvatarImage src={user.avatar} />
<AvatarFallback>{user.initials}</AvatarFallback>
</Avatar>
</div>
</div>
</header>
```
## Best Practices
### Component Organization
```tsx
// ✅ Good: Small, focused components
export function UserCard({ user }) {
return (
<Card>
<CardHeader>
<UserAvatar user={user} />
<UserDetails user={user} />
</CardHeader>
</Card>
)
}
// ❌ Avoid: Large monolithic components
export function DashboardPage() {
// 500 lines of JSX...
}
```
### Composability
```tsx
// ✅ Compose shadcn components
<DropdownMenu>
<DropdownMenuTrigger asChild>
<Button variant="ghost" size="icon">
<MoreVertical className="h-4 w-4" />
</Button>
</DropdownMenuTrigger>
<DropdownMenuContent align="end">
<DropdownMenuItem>Edit</DropdownMenuItem>
<DropdownMenuItem>Share</DropdownMenuItem>
<DropdownMenuSeparator />
<DropdownMenuItem className="text-destructive">
Delete
</DropdownMenuItem>
</DropdownMenuContent>
</DropdownMenu>
```
### State Management
```tsx
// Form state
const [formData, setFormData] = useState({ name: '', email: '' })
// Loading states
const [isLoading, setIsLoading] = useState(false)
// UI states
const [isOpen, setIsOpen] = useState(false)
```
### Error Handling
```tsx
<form onSubmit={handleSubmit} className="space-y-4">
<div className="space-y-2">
<Label htmlFor="email">Email</Label>
<Input
id="email"
type="email"
className={errors.email ? "border-destructive" : ""}
/>
{errors.email && (
<p className="text-sm text-destructive">{errors.email}</p>
)}
</div>
</form>
```
## Common Shadcn Components
### Essential Components
- **Layout**: Card, Tabs, Sheet, Dialog, Popover, Separator
- **Forms**: Input, Textarea, Select, Checkbox, Radio, Switch, Label
- **Buttons**: Button, Toggle, ToggleGroup
- **Display**: Badge, Avatar, Skeleton, Table
- **Feedback**: Alert, Toast, Progress
- **Navigation**: NavigationMenu, DropdownMenu, Command
### Button Variants
```tsx
<Button>Primary</Button>
<Button variant="secondary">Secondary</Button>
<Button variant="outline">Outline</Button>
<Button variant="ghost">Ghost</Button>
<Button variant="link">Link</Button>
<Button variant="destructive">Delete</Button>
```
### Badge Variants
```tsx
<Badge>Default</Badge>
<Badge variant="secondary">Secondary</Badge>
<Badge variant="outline">Outline</Badge>
<Badge variant="destructive">Error</Badge>
```
## Workflow
1. **Understand requirements** - What component/page is needed?
2. **Choose components** - Which shadcn/ui components fit?
3. **Build structure** - Layout and hierarchy first
4. **Apply styling** - Typography, spacing, colors
5. **Add interactions** - Hover states, transitions, focus
6. **Ensure accessibility** - ARIA, keyboard, contrast
7. **Test responsive** - Mobile, tablet, desktop
## Quality Checklist
Before completing:
- [ ] Uses shadcn/ui components appropriately
- [ ] Follows 4px spacing scale (p-2, p-4, p-6, etc.)
- [ ] Uses semantic color tokens (bg-card, text-foreground, etc.)
- [ ] Limited shadow usage (shadow-sm/md/lg only)
- [ ] Smooth transitions (200-300ms duration)
- [ ] ARIA labels on interactive elements
- [ ] Keyboard focus visible (ring-2 ring-primary)
- [ ] WCAG AA contrast ratios
- [ ] Mobile-responsive layout
- [ ] Loading and error states handled

# Solid Development
Fine-grained reactivity patterns for SolidJS.
## Instructions
SolidJS is NOT React. The mental model is fundamentally different:
| React | SolidJS |
|-------|---------|
| Components re-run on state change | Components run **once** |
| Virtual DOM diffing | Direct DOM updates |
| Hooks with dependency arrays | Automatic dependency tracking |
| `useState` returns value | `createSignal` returns getter function |
### 1. Signals — Reactive Primitives
Signals are getter/setter pairs that track dependencies automatically:
```jsx
import { createSignal } from "solid-js";
function Counter() {
const [count, setCount] = createSignal(0);
// ^ getter (function!) ^ setter
return (
<button onClick={() => setCount(c => c + 1)}>
Count: {count()} {/* Call the getter! */}
</button>
);
}
```
**Rules:**
- Always call the getter: `count()` not `count`
- The component function runs once — only the reactive parts update
- Signals accessed in JSX are automatically tracked
### 2. Effects — Side Effects
Effects run when their tracked signals change:
```jsx
import { createSignal, createEffect } from "solid-js";
function Logger() {
const [count, setCount] = createSignal(0);
// ✅ Tracked — runs when count changes
createEffect(() => {
console.log("Count is:", count());
});
// ❌ NOT tracked — runs once at setup
console.log("Initial:", count());
return <button onClick={() => setCount(c => c + 1)}>Increment</button>;
}
```
**Key insight:** Only signals accessed *inside* the effect are tracked.
### 3. Memos — Derived Values
Cache expensive computations:
```jsx
import { createSignal, createMemo } from "solid-js";
function FilteredList() {
const [items, setItems] = createSignal([]);
const [filter, setFilter] = createSignal("");
// Only recomputes when items or filter change
const filtered = createMemo(() =>
items().filter(item => item.includes(filter()))
);
return <For each={filtered()}>{item => <div>{item}</div>}</For>;
}
```
### 4. Props — Don't Destructure!
**Critical:** Destructuring props breaks reactivity.
```jsx
// ❌ BROKEN — loses reactivity
function Greeting({ name }) {
return <h1>Hello {name}</h1>;
}
// ❌ ALSO BROKEN
function Greeting(props) {
const { name } = props;
return <h1>Hello {name}</h1>;
}
// ✅ CORRECT — maintains reactivity
function Greeting(props) {
return <h1>Hello {props.name}</h1>;
}
```
**For defaults, use `mergeProps`:**
```jsx
import { mergeProps } from "solid-js";
function Button(props) {
const merged = mergeProps({ variant: "primary" }, props);
return <button class={merged.variant}>{merged.children}</button>;
}
```
**For splitting props, use `splitProps`:**
```jsx
import { splitProps } from "solid-js";
function Input(props) {
const [local, inputProps] = splitProps(props, ["label"]);
return (
<label>
{local.label}
<input {...inputProps} />
</label>
);
}
```
### 5. Control Flow Components
Don't use JS control flow in JSX — use Solid's components:
**Conditionals with `<Show>`:**
```jsx
import { Show } from "solid-js";
<Show when={isLoggedIn()} fallback={<Login />}>
<Dashboard />
</Show>
```
**Multiple conditions with `<Switch>`/`<Match>`:**
```jsx
import { Switch, Match } from "solid-js";
<Switch>
<Match when={status() === "loading"}>Loading...</Match>
<Match when={status() === "error"}>Error!</Match>
<Match when={status() === "success"}><Data /></Match>
</Switch>
```
**Lists with `<For>`:**
```jsx
import { For } from "solid-js";
<For each={items()}>
{(item, index) => <li>{index()}: {item.name}</li>}
</For>
```
**`<For>` vs `<Index>`:**
| Use | When |
|-----|------|
| `<For>` | List order/length changes (general case) |
| `<Index>` | Fixed positions, content changes (performance optimization) |
With `<Index>`, `item` is a signal: `{(item, i) => <div>{item().name}</div>}`
### 6. Stores — Complex State
Use stores for nested objects and shared state:
```jsx
import { createStore } from "solid-js/store";
function TodoApp() {
const [state, setState] = createStore({
todos: [],
filter: "all"
});
const addTodo = (text) => {
setState("todos", todos => [...todos, { text, done: false }]);
};
const toggleTodo = (index) => {
setState("todos", index, "done", done => !done);
};
return (/* ... */);
}
```
**When to use:**
- Signals: Simple values, local state
- Stores: Objects, arrays, shared state, nested data
### 7. Data Fetching with Resources
```jsx
import { createResource, Suspense } from "solid-js";
function UserProfile(props) {
const [user] = createResource(() => props.userId, fetchUser);
return (
<Suspense fallback={<Loading />}>
<Show when={user()} fallback={<NotFound />}>
<Profile user={user()} />
</Show>
</Suspense>
);
}
```
**Resource properties:**
- `user()` — the data (or undefined)
- `user.loading` — boolean
- `user.error` — error if failed
- `user.latest` — last successful value
### 8. Context for Shared State
```jsx
import { createContext, useContext } from "solid-js";
import { createStore } from "solid-js/store";
const AppContext = createContext();
function AppProvider(props) {
const [state, setState] = createStore({ user: null, theme: "light" });
return (
<AppContext.Provider value={[state, setState]}>
{props.children}
</AppContext.Provider>
);
}
function useApp() {
return useContext(AppContext);
}
```
## Common Mistakes
| Mistake | Problem | Fix |
|---------|---------|-----|
| `const { name } = props` | Breaks reactivity | Access `props.name` directly |
| `count` instead of `count()` | Gets function, not value | Call the signal getter |
| `console.log(count())` outside effect | Only runs once | Put in `createEffect` |
| Using `.map()` for lists | No keyed updates | Use `<For>` component |
| Ternary in JSX for conditionals | Works but less efficient | Use `<Show>` component |
| Multiple signals for related data | Verbose, hard to manage | Use `createStore` |
## Examples
### Complete Component Pattern
```jsx
import { createSignal, createMemo, createEffect, Show, For } from "solid-js";
function TaskList(props) {
const [filter, setFilter] = createSignal("all");
// Derived state
const filteredTasks = createMemo(() => {
const f = filter();
if (f === "all") return props.tasks;
return props.tasks.filter(t => (f === "done" ? t.done : !t.done));
});
// Side effect
createEffect(() => {
console.log(`Showing ${filteredTasks().length} tasks`);
});
return (
<div>
<select onChange={e => setFilter(e.target.value)}>
<option value="all">All</option>
<option value="done">Done</option>
<option value="pending">Pending</option>
</select>
<Show when={filteredTasks().length > 0} fallback={<p>No tasks</p>}>
<ul>
<For each={filteredTasks()}>
{task => (
<li classList={{ done: task.done }}>
{task.text}
</li>
)}
</For>
</ul>
</Show>
</div>
);
}
```

# TailwindCSS v4 Patterns
## Overview
TailwindCSS v4 introduces a CSS-first approach, eliminating the need for JavaScript configuration files. All customization happens directly in CSS using new directives.
## Key Changes from v3 to v4
| Feature | v3 | v4 |
|---------|-----|-----|
| Configuration | `tailwind.config.js` | CSS `@theme` directive |
| Content detection | JS array | `@source` directive |
| Plugin loading | `require()` in JS | `@plugin` directive |
| Custom variants | JS API | `@custom-variant` directive |
| Custom utilities | JS API | `@utility` directive |
## Browser Support
TailwindCSS v4 requires modern browsers:
- Safari 16.4+
- Chrome 111+
- Firefox 128+
**Important**: No CSS preprocessors (Sass/Less) needed - Tailwind IS the preprocessor.

## CSS-First Configuration
### Basic Setup
```css
/* src/index.css */
@import "tailwindcss";
```
This single import replaces the v3 directives (`@tailwind base`, `@tailwind components`, `@tailwind utilities`).
### @theme Directive - Design Tokens
The `@theme` directive defines design tokens as CSS custom properties:
```css
@import "tailwindcss";
@theme {
/* Colors */
--color-primary: hsl(221 83% 53%);
--color-primary-dark: hsl(224 76% 48%);
--color-secondary: hsl(215 14% 34%);
--color-accent: hsl(328 85% 70%);
/* With oklch (modern color space) */
--color-success: oklch(0.723 0.191 142.5);
--color-warning: oklch(0.828 0.189 84.429);
--color-error: oklch(0.637 0.237 25.331);
/* Typography */
--font-display: "Satoshi", "sans-serif";
--font-body: "Inter", "sans-serif";
--font-mono: "JetBrains Mono", "monospace";
/* Spacing */
--spacing-page: 2rem;
--spacing-section: 4rem;
/* Custom breakpoints */
--breakpoint-xs: 480px;
--breakpoint-3xl: 1920px;
/* Animation timing */
--ease-spring: cubic-bezier(0.68, -0.55, 0.265, 1.55);
--duration-fast: 150ms;
--duration-normal: 300ms;
}
```
**Generated utilities from above:**
- Colors: `bg-primary`, `text-primary-dark`, `border-accent`
- Fonts: `font-display`, `font-body`, `font-mono`
- Animations: `ease-spring`, `duration-fast`
### @theme inline Pattern
Use `@theme inline` to reference existing CSS variables without generating new utilities:
```css
/* Define CSS variables normally */
:root {
--background: oklch(1 0 0);
--foreground: oklch(0.145 0 0);
--card: oklch(1 0 0);
--primary: oklch(0.205 0 0);
}
.dark {
--background: oklch(0.145 0 0);
--foreground: oklch(0.985 0 0);
--primary: oklch(0.985 0 0);
}
/* Map to Tailwind utilities */
@theme inline {
--color-background: var(--background);
--color-foreground: var(--foreground);
--color-card: var(--card);
--color-primary: var(--primary);
}
```
**When to use `@theme inline`:**
- Theming with CSS variables (light/dark mode)
- Shadcn/ui integration
- Dynamic theme switching
### @source Directive - Content Detection
```css
@import "tailwindcss";
/* Default: Tailwind scans all git-tracked files */
/* Add additional sources */
@source "../node_modules/my-ui-library/src/**/*.{html,js}";
@source "../shared-components/**/*.tsx";
/* Safelist specific utilities */
@source inline("bg-red-500 text-white p-4");
```
### @custom-variant - Custom Variants
```css
@import "tailwindcss";
/* Dark mode variant (class-based) */
@custom-variant dark (&:is(.dark *));
/* RTL variant */
@custom-variant rtl ([dir="rtl"] &);
/* Print variant */
@custom-variant print (@media print { & });
/* Hover on desktop only */
@custom-variant hover-desktop (@media (hover: hover) { &:hover });
```
### @utility - Custom Utilities
```css
@import "tailwindcss";
/* Text balance utility */
@utility text-balance {
text-wrap: balance;
}
/* Scrollbar hide */
@utility scrollbar-hide {
-ms-overflow-style: none;
scrollbar-width: none;
&::-webkit-scrollbar {
display: none;
}
}
/* Flex center shorthand */
@utility flex-center {
display: flex;
align-items: center;
justify-content: center;
}
```
### @plugin - Plugin Configuration
```css
@import "tailwindcss";
/* Load a plugin */
@plugin "@tailwindcss/typography";
@plugin "@tailwindcss/forms";
@plugin "@tailwindcss/container-queries";
/* Plugin with options */
@plugin "@tailwindcss/typography" {
className: prose;
}
```
### @config - Legacy JS Configuration
When you need JS configuration (rare in v4):
```css
@import "tailwindcss";
@config "./tailwind.config.ts";
```
---
## Vite Integration
### Installation
```bash
npm install tailwindcss @tailwindcss/vite
```
### Vite Configuration
```typescript
// vite.config.ts
import tailwindcss from "@tailwindcss/vite"
import react from "@vitejs/plugin-react"
import path from "path"
import { defineConfig } from "vite"
export default defineConfig({
plugins: [react(), tailwindcss()],
resolve: {
alias: {
"@": path.resolve(__dirname, "./src"),
},
},
})
```
### CSS Entry Point
```css
/* src/index.css */
@import "tailwindcss";
@theme {
/* Your design tokens */
}
```
### TypeScript Path Aliases
```json
// tsconfig.json
{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"@/*": ["./src/*"]
}
}
}
```

## Modern CSS Features with Tailwind v4
### Native CSS Variables
Tailwind v4 uses native CSS variables without wrapper functions:
```css
/* v3 - Required hsl wrapper */
--primary: 221 83% 53%;
background-color: hsl(var(--primary));
/* v4 - Direct CSS value */
--color-primary: hsl(221 83% 53%);
/* Used as: bg-primary */
```
### oklch Color Format
```css
@theme {
/* oklch: lightness, chroma, hue */
--color-brand: oklch(0.65 0.2 250);
--color-brand-light: oklch(0.85 0.15 250);
--color-brand-dark: oklch(0.45 0.25 250);
}
```
**Benefits of oklch:**
- Perceptually uniform
- Consistent lightness across hues
- Better for generating color scales
- Native browser support
### Container Queries
```html
<!-- Parent needs @container -->
<div class="@container">
<!-- Child responds to container width -->
<div class="grid grid-cols-1 @md:grid-cols-2 @lg:grid-cols-3">
<!-- Content -->
</div>
</div>
```
```css
/* Named containers */
.sidebar {
container-name: sidebar;
container-type: inline-size;
}
/* Target named container */
@container sidebar (min-width: 300px) {
.nav-item { /* expanded styles */ }
}
```
### :has() Pseudo-Class
```html
<!-- Style parent based on child state -->
<label class="group has-[:invalid]:border-red-500 has-[:focus]:ring-2">
<input type="email" class="peer" />
</label>
```
```css
/* Card with image gets different padding */
.card:has(> img) {
@apply p-0;
}
/* Form with invalid fields */
.form:has(:invalid) {
@apply border-red-500;
}
```
### Native CSS Nesting
```css
.card {
@apply rounded-lg bg-white shadow-md;
.header {
@apply border-b p-4;
}
.content {
@apply p-6;
}
&:hover {
@apply shadow-lg;
}
&.featured {
@apply border-2 border-primary;
}
}
```
---
## Utility Patterns
### Responsive Design (Mobile-First)
```html
<!-- Breakpoints: sm(640px), md(768px), lg(1024px), xl(1280px), 2xl(1536px) -->
<div class="
p-4 text-sm /* Mobile */
sm:p-6 sm:text-base /* Tablet */
lg:p-8 lg:text-lg /* Desktop */
2xl:p-12 2xl:text-xl /* Large screens */
">
```
### State Variants
```html
<!-- Hover, focus, active -->
<button class="
bg-primary text-white
hover:bg-primary-dark
focus:ring-2 focus:ring-primary focus:ring-offset-2
active:scale-95
disabled:opacity-50 disabled:cursor-not-allowed
">
<!-- Group hover -->
<div class="group">
<span class="group-hover:underline">Label</span>
<span class="opacity-0 group-hover:opacity-100">Icon</span>
</div>
<!-- Peer focus -->
<input class="peer" />
<span class="invisible peer-focus:visible">Hint text</span>
```
### Dark Mode
**Strategy 1: Class-based (recommended)**
```css
@custom-variant dark (&:is(.dark *));
```
```html
<html class="dark">
<body class="bg-white dark:bg-gray-900 text-black dark:text-white">
```
**Strategy 2: Media query**
```css
@custom-variant dark (@media (prefers-color-scheme: dark) { & });
```
### Animation Utilities
```html
<!-- Built-in animations -->
<div class="animate-spin" />
<div class="animate-pulse" />
<div class="animate-bounce" />
<!-- Custom animation -->
<div class="animate-[fadeIn_0.5s_ease-out]" />
```
```css
@theme {
--animate-fade-in: fadeIn 0.5s ease-out;
}
@keyframes fadeIn {
from { opacity: 0; transform: translateY(-10px); }
to { opacity: 1; transform: translateY(0); }
}
```
### Size Utility (v4)
```html
<!-- v3: Two classes -->
<div class="w-10 h-10">
<!-- v4: Single class -->
<div class="size-10">
```
---
## Best Practices
### When to Use @apply
Use `@apply` sparingly for true component abstraction:
```css
/* Good: Repeated pattern across many components */
@layer components {
.btn-primary {
@apply px-4 py-2 bg-primary text-white rounded-md;
@apply hover:bg-primary-dark focus:ring-2 focus:ring-primary;
@apply disabled:opacity-50 disabled:cursor-not-allowed;
@apply transition-colors duration-fast;
}
}
/* Bad: One-off styling (just use utilities in HTML) */
.my-special-div {
@apply mt-4 p-6 bg-gray-100; /* Just put these in className */
}
```
**Rule**: Only extract patterns when reused 3+ times.
### Design Token Naming
```css
@theme {
/* Semantic naming (preferred) */
--color-primary: hsl(221 83% 53%);
--color-primary-foreground: hsl(0 0% 100%);
/* Not: --color-blue-600: ... */
/* Scale naming when needed */
--color-gray-50: oklch(0.985 0 0);
--color-gray-100: oklch(0.970 0 0);
--color-gray-900: oklch(0.145 0 0);
}
```
### Performance
1. **Use Vite plugin** - Automatic dead code elimination
2. **Avoid dynamic class names** - Static analysis can't optimize them
3. **Purge unused styles** - Automatic with proper @source config
```html
<!-- Good: Static class names -->
<div class={isActive ? "bg-primary" : "bg-gray-100"}>
<!-- Bad: Dynamic class construction -->
<div class={`bg-${color}-500`}> <!-- Can't be purged -->
```
### CSS Layers Order
Tailwind v4 uses CSS cascade layers:
```
1. @layer base - Reset, typography defaults
2. @layer components - Reusable components
3. @layer utilities - Utility classes (highest priority)
```
Custom styles should go in appropriate layers:
```css
@layer components {
.card { /* component styles */ }
}
@layer utilities {
.text-shadow { /* utility styles */ }
}
```

# 🎨 Shadcn UI + Tailwind CSS 视觉设计标准
## 核心设计理念
1. **原子化优先**: 所有样式必须通过 Tailwind Utility Classes 实现,严禁手写 CSS/SASS 文件。
2. **极简主义**: 遵循 Shadcn 默认的黑白灰基调,强调排版与留白,通过 `ring-offset``muted-foreground` 等细节提升质感。
3. **可定制主题**: 所有颜色引用必须基于 CSS 变量(如 `bg-primary`, `text-secondary`),严禁使用 Hex/RGB 硬编码,以支持深色模式切换。
## 🧩 组件视觉规范
### 1. 颜色系统 (Color System)
- **Primary**: 主色调,用于主要按钮、激活状态。
- **Secondary**: 次级色,用于次要操作、非强调背景。
- **Destructive**: 破坏性操作(如删除),通常为红色系。
- **Muted**: 弱化文本与背景,用于辅助说明。
- **Accent**: 强调色,用于 Hover、Focus 状态。
- **Background/Foreground**: 页面背景与主文本色。
**开发约束**:
- ✅ 正确: `<div class="bg-primary text-primary-foreground">`
- ❌ 错误: `<div class="bg-[#000] text-white">`
### 2. 布局与间距 (Layout & Spacing)
- **Container**: 必须使用 `container mx-auto` 进行主内容居中。
- **Grid System**: 使用 `grid-cols-1 md:grid-cols-3` 等响应式网格。
- **Spacing**:
- 小间距: `gap-2` (0.5rem)
- 组件间距: `gap-4` (1rem)
- 区块间距: `py-8` / `my-10`
- **Radius**: 全局圆角统一使用 `rounded-md``rounded-lg`,保持风格一致。
### 3. 排版 (Typography)
- **Headings**:
- H1: `text-4xl font-extrabold tracking-tight lg:text-5xl`
- H2: `text-3xl font-semibold tracking-tight first:mt-0`
- H3: `text-2xl font-semibold tracking-tight`
- **Body**: `leading-7 [&:not(:first-child)]:mt-6`
- **Small/Muted**: `text-sm text-muted-foreground`
### 4. 交互反馈 (Interaction)
- **Hover**: 所有可交互元素必须有 hover 态。
- 按钮: `hover:bg-primary/90`
- 卡片: `hover:bg-accent hover:text-accent-foreground`
- **Focus**: 必须保留键盘焦点的可见性。
- 标准: `focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2`
- **Disabled**: `disabled:pointer-events-none disabled:opacity-50`

## 🔍 代码审计要点 (@code-spec)
@code-spec 执行审计时,必须检查以下条目:
1. **硬编码颜色检查**:
- 检查是否使用了 `#ffffff`, `rgb(0,0,0)` 等硬编码颜色值? (必须替换为 `bg-background` 等)
2. **Tailwind 冲突检查**:
- 检查是否混用了 `style={{ ... }}``className`? (应完全移除 `style`)
- 检查是否使用了 `cn()` 合并类名? (例如组件封装时)
3. **响应式断点**:
- 检查主要的布局容器是否包含了移动端优先的类名 (e.g. `w-full md:w-auto`)?
---
## 🧪 测试与验收标准 (@qa-tester)
@qa-tester 执行测试时,必须验证以下指标:
1. **深色模式 (Dark Mode)**
- 切换到深色模式后,所有背景是否自动变黑? 文字是否自动变白?
- 检查是否有难以辨认的低对比度文本(如深灰色字在黑色背景上)。
2. **移动端适配**
- 在 375px 宽度下Grid 布局是否自动堆叠为单列 (`grid-cols-1`)?
- 没有任何横向滚动条出现。
3. **无障碍 (a11y)**
- 使用 Tab 键能否遍历所有按钮和链接,并且有明显的 Ring 焦点样式?

tags: [bun, solid, elysia, shadcn, ssr]
---
# 🚀 Bun + SolidJS + ElysiaJS + Shadcn 技术栈规范
## 🛡️ 核心架构与约束 (Architecture & Constraints)
### 1. 运行时与构建 (Bun.js)
- **Runtime**:强制使用 `Bun.serve()` 作为 HTTP 服务器。
- **Build**: 使用 `Bun.build()` 及其插件系统。
- **Testing**: 必须使用 `bun:test` 替代 Jest/Vitest。
- **Database**: 强制使用 **TypeORM** + **SQLite**。必须使用 Repository 模式进行数据访问,禁止在 Controller 中直接编写 SQL。
- **Package Manager**: 必须使用 `bun install / add / run`。严禁使用 `npm``yarn`
### 2. 前端框架 (SolidJS & Solid Start)
- **Reactivity**:
- **严禁**解构 Props (会导致响应式丢失)。必须使用 `props.value``splitProps`
- **严禁**使用 `mcp_chrome-devtools` 调试时依赖 React DevTools 思维。Solid 是细粒度更新,无 VDOM diff。
- **控制流**: 必须使用 `<Show>`, `<For>`, `<Switch>` 等内置组件,禁止使用 `array.map()` 或三元运算符直接渲染列表/条件。
- **SSR/Hydration**:
- 服务端数据预取必须在 `routeData``createServerData$` 中完成。
- 禁止在 `onMount` 中执行影响首屏内容的操作(会导致水合不匹配)。
### 3. 后端服务 (ElysiaJS)
- **Type Safety**: 必须使用 `t.Object` / `t.String` 等 Elysia 类型系统定义 DTO。
- **Validation**:所有 API 必须有 schema 验证。
- **Performance**: 路由注册应当利用 Elysia 的 AOT 编译特性,避免动态路由过度嵌套。
### 4. UI 组件库 (Shadcn-solid + Tailwind)
- **Styling**:
- 禁止书写 `style` 属性或 CSS 文件。必须使用 Tailwind Utility Classes。
- 必须使用 `cn()` (clsx + tailwind-merge) 处理动态类名。
- **Components**:
- 优先复用 Shadcn-solid 组件。
- 自定义组件必须支持 `class``classList` 属性透传。
- **Dark Mode**: 必须通过 CSS 变量和 Tailwind `dark:` 前缀适配深色模式。
### 5. 移动端适配与国际化 (Mobile & i18n)
- **Responsive Design**:
- 必须采用 **Mobile-First** 策略:默认样式为移动端,使用 `mm:`, `lg:` 等断点覆盖 PC 端样式。
- 严禁使用固定像素宽度 (px) 定义主要容器,必须使用百分比、`rem` 或 Tailwind 的 `container`/`w-full`
- 交互适配Touch事件与Hover状态必须兼容使用 `@media (hover: hover)` 处理仅 PC 显示的交互)。
- **Internationalization (i18n)**:
- 必须集成 `@solid-primitives/i18n` 或 Solid Start 官方推荐的 i18n 方案。
- **严禁**在 JSX 中硬编码文本。所有文案必须提取到 `dictionaries``locales` 资源文件中。
- **SSR支持**: 服务端必须解析请求头 `Accept-Language` 或 URL 前缀,在 SSR 阶段注入当前语言字典,杜绝客户端水合时的内容闪烁。
---
## 🔍 代码审计要点 (@code-spec)
@code-spec 执行审计时,必须检查以下条目:
1. **响应式丢失检查**:
- 检查组件 Props 是否被解构? (e.g. `const { name } = props` -> ❌)
2. **控制流优化**:
- 检查是否使用了 `<For>` 而不是 `.map()`? (Solid 的 `<For>` 对 keyed items 做了优化)
3. **类型安全**:
- Elysia 路由是否有 `body`, `query`, `params``t.*` 定义?
4. **Bun 兼容性**:
- 是否引用了 Node.js 特有且 Bun 未实现的 API? (需查阅 Bun 兼容性表)
5. **样式规范**:
- 是否存在硬编码颜色值? (应使用 CSS 变量如 `bg-background` `text-primary`)
6. **国际化规范**:
- 检查组件中是否存在硬编码的中文/英文字符串? (❌ `<span>登录</span>` -> ✅ `<span>{t('login')}</span>`)
7. **响应式检查**:
- 检查是否通过 `md:`, `lg:` 等断点处理了布局变化? 是否存在大块固定 `px` 宽度的容器?
8. **ORM 规范**:
- 是否正确使用了 TypeORM 的 `@Entity` 定义模型?
- 是否通过 Repository 进行数据操作? (严禁裸写 SQL)
---
## 🧪 测试与验收标准 (@qa-tester)
@qa-tester 执行测试时,必须验证以下指标:
### 1. 性能指标 (Performance)
- **SSR 渲染耗时**: < 50ms (利用 Bun 高性能 RSC 渲染)
- **首屏加载 (LCP)**: < 1.0s
- **水合错误 (Hydration)**: 控制台 **0** Error/Warning
### 2. 功能测试
- **路由跳转**: 必须是 SPA 模式(无全页刷新)。
- **表单交互**: 提交后必须有 Loading 状态,支持 Enter 提交。
### 3. 兼容性
- **No-JS 支持**: 核心内容在禁用 JavaScript 时必须可见 (SSR 直出)。
- **浏览器**: Chrome, Safari, Firefox 最新版。
### 4. 多端与多语言测试
- **Viewport**: 必须覆盖 iPhone SE (375px), iPad Mini (768px), Desktop (1280px+)。
- **Touch**: 移动端下按钮点击区域必须 >= 44x44px。
- **i18n**:
- 切换语言必须即时生效(或路由跳转)。
- 刷新页面后,当前语言状态必须保持。
- 检查是否存在未翻译的原始 Key 显示在界面上。

# Bun.js Clean Architecture Patterns
## Overview
This skill covers layered architecture, clean code patterns, camelCase naming conventions, and structured implementation workflows for Bun.js TypeScript backend applications. Use this skill when building complex, maintainable applications that require strict separation of concerns.
**When to use this skill:**
- Implementing layered architecture (routes → controllers → services → repositories)
- Establishing coding conventions and naming standards
- Designing database schemas with Prisma
- Creating API endpoint specifications
- Planning implementation workflows
**See also:**
- **dev:bunjs** - Core Bun patterns, HTTP servers, basic database access
- **dev:bunjs-production** - Production deployment, Docker, AWS, Redis
- **dev:bunjs-apidog** - OpenAPI specifications and Apidog integration
## Clean Architecture Principles
### 1. Layered Architecture
**ALWAYS** separate concerns into distinct layers with single responsibilities:
```
┌─────────────────────────────────────┐
│ Routes Layer │ ← Define API routes, attach middleware
│ (src/routes/) │ Map to controllers
└──────────────┬──────────────────────┘
┌──────────────▼──────────────────────┐
│ Controllers Layer │ ← Handle HTTP requests/responses
│ (src/controllers/) │ Call services, no business logic
└──────────────┬──────────────────────┘
┌──────────────▼──────────────────────┐
│ Services Layer │ ← Implement business logic
│ (src/services/) │ Orchestrate repositories
└──────────────┬──────────────────────┘ No HTTP concerns
┌──────────────▼──────────────────────┐
│ Repositories Layer │ ← Encapsulate database access
│ (src/database/repositories/) │ Use Prisma, type-safe queries
└─────────────────────────────────────┘ No business logic
```
**Critical Rules:**
- Controllers NEVER contain business logic (only HTTP handling)
- Services NEVER access HTTP context (no `req`, `res`, `Context`)
- Repositories are the ONLY layer that touches Prisma/database
- Each layer depends only on layers below it
### 2. Dependency Flow
```typescript
// ✅ CORRECT: Downward dependency flow
Routes Controllers Services Repositories Database
// ❌ WRONG: Upward dependency (service accessing controller)
Service imports from Controller // NEVER DO THIS
// ❌ WRONG: Skip layers (controller accessing repository directly)
Controller Repository // Should go through Service
```
### 3. Separation of Concerns
| Layer | Responsibilities | Forbidden |
|-------|------------------|-----------|
| **Routes** | Define endpoints, attach middleware, map to controllers | Business logic, DB access |
| **Controllers** | Extract data from HTTP, call services, format responses | Business logic, DB access, validation logic |
| **Services** | Business logic, orchestrate operations, manage transactions | HTTP handling, direct DB access |
| **Repositories** | Database queries, type-safe Prisma operations | Business logic, HTTP handling |
## camelCase Conventions (CRITICAL)
### Why camelCase Everywhere?
**TypeScript-first full-stack development requires ONE naming convention across all layers:**
- ✅ Database → Prisma → TypeScript → API → Frontend (1:1 mapping)
- ✅ Zero translation layer = zero mapping bugs
- ✅ Autocomplete works perfectly everywhere
- ✅ Type safety maintained end-to-end
**This is non-negotiable for our stack.**
### API Field Naming: camelCase
**CRITICAL: All JSON REST API field names MUST use camelCase.**
**Why:**
- ✅ Native to JavaScript/JSON - No transformation needed
- ✅ Industry standard - Google, Microsoft, Facebook, AWS use camelCase
- ✅ TypeScript friendly - Direct mapping to interfaces
- ✅ OpenAPI/Swagger convention - Standard for API specs
- ✅ Auto-generated clients - Expected by code generation tools
**Examples:**
```typescript
// ✅ CORRECT: camelCase
{
"userId": "123",
"firstName": "John",
"lastName": "Doe",
"emailAddress": "john@example.com",
"createdAt": "2025-01-06T12:00:00Z",
"isActive": true,
"phoneNumber": "+1234567890"
}
// ❌ WRONG: snake_case
{
"user_id": "123",
"first_name": "John",
"created_at": "2025-01-06T12:00:00Z"
}
// ❌ WRONG: PascalCase
{
"UserId": "123",
"FirstName": "John"
}
```
**Consistent Application:**
1. **Request Bodies**: All fields in camelCase
2. **Response Bodies**: All fields in camelCase
3. **Query Parameters**: Use camelCase (`pageSize`, `sortBy`, `orderBy`)
4. **Zod Schemas**: Define fields in camelCase
5. **TypeScript Interfaces**: Match API camelCase
### Database Naming: camelCase
**CRITICAL: All database identifiers (tables, columns, indexes, constraints) use camelCase.**
**Why:**
- ✅ Stack consistency - TypeScript is our primary language
- ✅ Zero translation layer - Database names map 1:1 with TypeScript types
- ✅ Reduced complexity - No snake_case ↔ camelCase conversion
- ✅ Modern ORM compatibility - Prisma, Drizzle, TypeORM work seamlessly
- ✅ Team productivity - Full-stack TypeScript developers think in camelCase
**Naming Rules:**
**1. Tables:** Singular, camelCase with `@@map()` to plural
```prisma
model User {
userId String @id
// ...
@@map("users") // Table name: users
}
```
**2. Columns:** camelCase
```prisma
userId, firstName, emailAddress, createdAt, isActive
```
**3. Primary Keys:** `{tableName}Id`
```prisma
userId // in users table
orderId // in orders table
productId // in products table
```
**4. Foreign Keys:** Same as referenced primary key
```prisma
model Order {
orderId String @id
userId String // references users.userId
user User @relation(fields: [userId], references: [userId])
}
```
**5. Boolean Fields:** Prefix with is/has/can
```prisma
isActive, isDeleted, isPublic
hasPermission, hasAccess
canEdit, canDelete
```
**6. Timestamps:** Consistent suffixes
```prisma
createdAt // creation time
updatedAt // last modification
deletedAt // soft delete time
lastLoginAt // specific event times
publishedAt
verifiedAt
```
**7. Indexes:** `idx{TableName}{ColumnName}`
```prisma
@@index([emailAddress], name: "idxUsersEmailAddress")
@@index([userId, createdAt], name: "idxOrdersUserIdCreatedAt")
```
**8. Constraints:**
```prisma
// Foreign keys (Prisma auto-generates, but can specify)
@@index([userId], map: "fkOrdersUserId")
// Unique constraints
@@unique([emailAddress], name: "unqUsersEmailAddress")
```
### Prisma Schema Example (Perfect Mapping)
```prisma
model User {
userId String @id @default(cuid())
emailAddress String @unique
firstName String?
lastName String?
phoneNumber String?
isActive Boolean @default(true)
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
lastLoginAt DateTime?
orders Order[]
sessions Session[]
@@index([emailAddress], name: "idxUsersEmailAddress")
@@index([createdAt], name: "idxUsersCreatedAt")
@@map("users")
}
model Order {
orderId String @id @default(cuid())
userId String
totalAmount Decimal @db.Decimal(10, 2)
orderStatus String
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
user User @relation(fields: [userId], references: [userId])
orderItems OrderItem[]
@@index([userId], name: "idxOrdersUserId")
@@index([createdAt], name: "idxOrdersCreatedAt")
@@map("orders")
}
model OrderItem {
orderItemId String @id @default(cuid())
orderId String
productId String
quantity Int
unitPrice Decimal @db.Decimal(10, 2)
order Order @relation(fields: [orderId], references: [orderId])
@@index([orderId], name: "idxOrderItemsOrderId")
@@map("orderItems")
}
```
### TypeScript Types (Perfect Match)
```typescript
// Exact 1:1 mapping with database and API
interface User {
userId: string;
emailAddress: string;
firstName: string | null;
lastName: string | null;
phoneNumber: string | null;
isActive: boolean;
createdAt: Date;
updatedAt: Date;
lastLoginAt: Date | null;
}
interface Order {
orderId: string;
userId: string;
totalAmount: number;
orderStatus: string;
createdAt: Date;
updatedAt: Date;
}
```
### Benefits of Single Convention
**No Translation Needed:**
```typescript
// Database column
userId
// Prisma model
userId
// TypeScript type
userId
// API response
userId
// Frontend state
userId
// All identical → zero translation → zero bugs ✓
```
## Layer Templates
### Route Template
```typescript
// src/routes/user.routes.ts
import { Hono } from 'hono';
import * as userController from '@/controllers/user.controller';
import { validate, validateQuery } from '@middleware/validator';
import { authenticate, authorize } from '@middleware/auth';
import { createUserSchema, updateUserSchema, getUsersQuerySchema } from '@/schemas/user.schema';
const userRouter = new Hono();
// Public routes
userRouter.get('/', validateQuery(getUsersQuerySchema), userController.getUsers);
userRouter.get('/:id', userController.getUserById);
userRouter.post('/', validate(createUserSchema), userController.createUser);
// Protected routes
userRouter.patch('/:id', authenticate, validate(updateUserSchema), userController.updateUser);
userRouter.delete('/:id', authenticate, authorize('admin'), userController.deleteUser);
export default userRouter;
```
### Controller Template
```typescript
// src/controllers/user.controller.ts
import type { Context } from 'hono';
import * as userService from '@/services/user.service';
import type { CreateUserDto, UpdateUserDto, GetUsersQuery } from '@/schemas/user.schema';
export const createUser = async (c: Context) => {
const data = c.get('validatedData') as CreateUserDto;
const user = await userService.createUser(data);
return c.json(user, 201);
};
export const getUserById = async (c: Context) => {
const id = c.req.param('id');
const user = await userService.getUserById(id);
return c.json(user);
};
export const getUsers = async (c: Context) => {
const query = c.get('validatedQuery') as GetUsersQuery;
const result = await userService.getUsers(query);
return c.json(result);
};
export const updateUser = async (c: Context) => {
const id = c.req.param('id');
const data = c.get('validatedData') as UpdateUserDto;
const user = await userService.updateUser(id, data);
return c.json(user);
};
export const deleteUser = async (c: Context) => {
const id = c.req.param('id');
await userService.deleteUser(id);
return c.json({ message: 'User deleted successfully' });
};
```
**Controller Rules:**
- ✅ Extract validated data from context
- ✅ Call service layer functions
- ✅ Format HTTP responses
- ❌ NO business logic
- ❌ NO database access
- ❌ NO validation logic (use middleware)
### Service Template
```typescript
// src/services/user.service.ts
import { userRepository } from '@/database/repositories/user.repository';
import { NotFoundError, ConflictError } from '@core/errors';
import type { CreateUserDto, UpdateUserDto, GetUsersQuery } from '@/schemas/user.schema';
import bcrypt from 'bcrypt';
export const createUser = async (data: CreateUserDto) => {
// Check for conflicts
if (await userRepository.exists(data.emailAddress)) {
throw new ConflictError('Email already exists');
}
// Hash password (business logic)
const hashedPassword = await bcrypt.hash(data.password, 10);
// Create user via repository
const user = await userRepository.create({
...data,
password: hashedPassword
});
// Strip sensitive data before returning
const { password, ...withoutPassword } = user;
return withoutPassword;
};
export const getUserById = async (id: string) => {
const user = await userRepository.findById(id);
if (!user) throw new NotFoundError('User');
const { password, ...withoutPassword } = user;
return withoutPassword;
};
export const getUsers = async (query: GetUsersQuery) => {
const { page, limit, sortBy, order, role } = query;
const { users, total } = await userRepository.findMany({
skip: (page - 1) * limit,
take: limit,
where: role ? { role } : undefined,
orderBy: sortBy ? { [sortBy]: order } : { createdAt: order }
});
return {
data: users.map(({ password, ...u }) => u),
pagination: {
page,
limit,
total,
totalPages: Math.ceil(total / limit)
}
};
};
export const updateUser = async (id: string, data: UpdateUserDto) => {
const existing = await userRepository.findById(id);
if (!existing) throw new NotFoundError('User');
// Hash password if provided
if (data.password) {
data.password = await bcrypt.hash(data.password, 10);
}
const user = await userRepository.update(id, data);
const { password, ...withoutPassword } = user;
return withoutPassword;
};
export const deleteUser = async (id: string) => {
const existing = await userRepository.findById(id);
if (!existing) throw new NotFoundError('User');
await userRepository.delete(id);
};
```
**Service Rules:**
- ✅ Implement business logic
- ✅ Orchestrate multiple repository calls
- ✅ Handle transactions
- ✅ Throw custom errors
- ❌ NO HTTP handling (no Context, Request, Response)
- ❌ NO direct Prisma calls (use repositories)
### Repository Template
```typescript
// src/database/repositories/user.repository.ts
import { prisma } from '@/database/client';
import type { Prisma, User } from '@prisma/client';
export class UserRepository {
findById(id: string): Promise<User | null> {
return prisma.user.findUnique({ where: { userId: id } });
}
findByEmail(email: string): Promise<User | null> {
return prisma.user.findUnique({ where: { emailAddress: email } });
}
create(data: Prisma.UserCreateInput): Promise<User> {
return prisma.user.create({ data });
}
update(id: string, data: Prisma.UserUpdateInput): Promise<User> {
return prisma.user.update({
where: { userId: id },
data
});
}
async delete(id: string): Promise<void> {
await prisma.user.delete({ where: { userId: id } });
}
async exists(email: string): Promise<boolean> {
return (await prisma.user.count({ where: { emailAddress: email } })) > 0;
}
async findMany(options: {
skip?: number;
take?: number;
where?: Prisma.UserWhereInput;
orderBy?: Prisma.UserOrderByWithRelationInput;
}): Promise<{ users: User[]; total: number }> {
const [users, total] = await prisma.$transaction([
prisma.user.findMany(options),
prisma.user.count({ where: options.where })
]);
return { users, total };
}
}
export const userRepository = new UserRepository();
```
**Repository Rules:**
- ✅ Encapsulate ALL database access
- ✅ Use Prisma's type-safe API
- ✅ Handle transactions when needed
- ✅ Return Prisma types
- ❌ NO business logic
- ❌ NO HTTP handling
### Schema Template (Zod)
```typescript
// src/schemas/user.schema.ts
import { z } from 'zod';
export const createUserSchema = z.object({
emailAddress: z.string().email(),
password: z.string()
.min(8, 'Password must be at least 8 characters')
.regex(/[A-Z]/, 'Password must contain uppercase letter')
.regex(/[a-z]/, 'Password must contain lowercase letter')
.regex(/[0-9]/, 'Password must contain number')
.regex(/[^A-Za-z0-9]/, 'Password must contain special character'),
firstName: z.string().min(2).max(100),
lastName: z.string().min(2).max(100),
phoneNumber: z.string().optional(),
role: z.enum(['user', 'admin', 'moderator']).default('user')
});
export const updateUserSchema = createUserSchema.partial();
export const getUsersQuerySchema = z.object({
page: z.coerce.number().positive().default(1),
limit: z.coerce.number().positive().max(100).default(20),
sortBy: z.enum(['createdAt', 'firstName', 'emailAddress']).optional(),
order: z.enum(['asc', 'desc']).default('desc'),
role: z.enum(['user', 'admin', 'moderator']).optional()
});
export type CreateUserDto = z.infer<typeof createUserSchema>;
export type UpdateUserDto = z.infer<typeof updateUserSchema>;
export type GetUsersQuery = z.infer<typeof getUsersQuerySchema>;
```
**Schema Rules:**
- ✅ Use camelCase for all field names
- ✅ Export TypeScript types via `z.infer`
- ✅ Provide clear error messages
- ✅ Use `.partial()` for update schemas
- ✅ Use `.default()` for query parameters
## Implementation Workflow
When implementing a new feature, follow this 9-phase workflow:
### Phase 1: Analysis & Planning
1. Read existing codebase to understand patterns
2. Identify required layers (routes, controllers, services, repositories)
3. Check for existing utilities/middleware to reuse
4. Plan database schema changes (if needed)
### Phase 2: Database Schema (if needed)
1. Design Prisma schema with camelCase conventions
2. Define models, relations, indexes
3. Create migration: `bunx prisma migrate dev --name <name>`
4. Generate Prisma client: `bunx prisma generate`
### Phase 3: Validation Layer
1. Define Zod schemas in `src/schemas/` with camelCase fields
2. Export TypeScript types from schemas
3. Ensure all request data is validated (body, query, params)
### Phase 4: Repository Layer (if needed)
1. Create/update repository class in `src/database/repositories/`
2. Implement methods (findById, create, update, delete, findMany)
3. Use Prisma types (`Prisma.UserCreateInput`, etc.)
4. Handle transactions where needed
### Phase 5: Business Logic Layer
1. Implement service functions in `src/services/`
2. Use repositories for data access
3. Implement business rules and orchestration
4. Handle errors with custom error classes
5. NEVER access HTTP context in services
### Phase 6: HTTP Layer
1. Create controller functions in `src/controllers/`
2. Extract validated data from context
3. Call service functions
4. Format responses (success/error)
5. NEVER implement business logic in controllers
### Phase 7: Routing Layer
1. Define routes in `src/routes/`
2. Attach middleware (validation, auth, etc.)
3. Map routes to controller functions
4. Group related routes in route files
### Phase 8: Testing
1. Write unit tests for services (`tests/unit/services/`)
2. Write integration tests for API endpoints (`tests/integration/api/`)
3. Test error cases and edge cases
4. Use Bun's test runner: `bun test`
### Phase 9: Quality Assurance
1. Run formatter: `bun run format`
2. Run linter: `bun run lint`
3. Run type checker: `bun run typecheck`
4. Run tests: `bun test`
5. Review code for security issues
6. Check logging is appropriate (no sensitive data)
## Database Schema Design Best Practices
### 1. Primary Keys
```prisma
// ✅ CORRECT: Use cuid() for user-facing IDs
model User {
userId String @id @default(cuid())
}
// ✅ CORRECT: Use uuid() for internal IDs
model Order {
orderId String @id @default(uuid())
}
// ❌ WRONG: Auto-incrementing integers expose system info
model User {
userId Int @id @default(autoincrement())
}
```
### 2. Timestamps
```prisma
// ✅ CORRECT: Always include created and updated timestamps
model User {
userId String @id @default(cuid())
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
}
// ✅ CORRECT: Add specific event timestamps when needed
model User {
lastLoginAt DateTime?
verifiedAt DateTime?
deletedAt DateTime? // For soft deletes
}
```
### 3. Relations
```prisma
// ✅ CORRECT: Bidirectional relations
model User {
userId String @id @default(cuid())
orders Order[]
}
model Order {
orderId String @id @default(cuid())
userId String
user User @relation(fields: [userId], references: [userId])
}
// ✅ CORRECT: Many-to-many with explicit join table
model Post {
postId String @id @default(cuid())
tags PostTag[]
}
model Tag {
tagId String @id @default(cuid())
posts PostTag[]
}
model PostTag {
postId String
tagId String
post Post @relation(fields: [postId], references: [postId])
tag Tag @relation(fields: [tagId], references: [tagId])
@@id([postId, tagId])
}
```
### 4. Indexes
```prisma
// ✅ CORRECT: Index frequently queried fields
model User {
emailAddress String @unique
firstName String
createdAt DateTime @default(now())
@@index([emailAddress]) // For lookups
@@index([createdAt]) // For sorting
@@index([firstName, lastName]) // Compound index for searches
}
```
### 5. Enums
```prisma
// ✅ CORRECT: Use enums for constrained values
enum UserRole {
USER
ADMIN
MODERATOR
}
model User {
role UserRole @default(USER)
}
// ❌ WRONG: Using strings without constraints
model User {
role String // Can be anything, no validation
}
```
## API Endpoint Design Patterns
### 1. RESTful Resource Naming
```
✅ CORRECT:
GET /api/users → List users
POST /api/users → Create user
GET /api/users/:id → Get user
PATCH /api/users/:id → Update user (partial)
PUT /api/users/:id → Replace user (full)
DELETE /api/users/:id → Delete user
GET /api/users/:id/orders → User's orders (nested resource)
POST /api/users/:id/orders → Create order for user
❌ WRONG:
GET /api/getUsers
POST /api/createUser
GET /api/user/:id (singular)
```
### 2. Query Parameters (camelCase)
```typescript
// ✅ CORRECT
GET /api/users?pageSize=20&sortBy=createdAt&orderBy=desc&isActive=true
// Query schema
const getUsersQuerySchema = z.object({
pageSize: z.coerce.number().positive().max(100).default(20),
sortBy: z.enum(['createdAt', 'firstName', 'emailAddress']).optional(),
orderBy: z.enum(['asc', 'desc']).default('desc'),
isActive: z.coerce.boolean().optional()
});
```
### 3. Response Formats
```typescript
// ✅ CORRECT: List response with pagination
{
"data": [
{ "userId": "123", "firstName": "John", "emailAddress": "john@example.com" }
],
"pagination": {
"page": 1,
"pageSize": 20,
"total": 150,
"totalPages": 8
}
}
// ✅ CORRECT: Single resource response
{
"data": {
"userId": "123",
"firstName": "John",
"emailAddress": "john@example.com",
"createdAt": "2025-01-06T12:00:00Z"
}
}
// ✅ CORRECT: Error response
{
"statusCode": 422,
"type": "ValidationError",
"message": "Invalid request data",
"details": [
{ "field": "emailAddress", "message": "Invalid email format" }
]
}
```
## Consistency Checklist
Before implementing any feature, ensure consistency with the existing codebase:
- [ ] Reviewed existing route patterns
- [ ] Checked naming conventions (all camelCase)
- [ ] Verified error handling approach
- [ ] Confirmed middleware usage patterns
- [ ] Validated layering approach (routes → controllers → services → repositories)
- [ ] Checked for reusable utilities
- [ ] Confirmed validation patterns (Zod schemas)
- [ ] Verified test structure
**NEVER introduce new patterns without explicit approval.**

# ElysiaJS Development Skill
Always consult [elysiajs.com/llms.txt](https://elysiajs.com/llms.txt) for code examples and latest API.
## Overview
ElysiaJS is a TypeScript framework for building Bun-first (but not limited to Bun) type-safe, high-performance backend servers. This skill provides comprehensive guidance for developing with Elysia, including routing, validation, authentication, plugins, integrations, and deployment.
## When to Use This Skill
Trigger this skill when the user asks to:
- Create or modify ElysiaJS routes, handlers, or servers
- Setup validation with TypeBox or other schema libraries (Zod, Valibot)
- Implement authentication (JWT, session-based, macros, guards)
- Add plugins (CORS, OpenAPI, Static files, JWT)
- Integrate with external services (Drizzle ORM, Better Auth, Next.js, Eden Treaty)
- Setup WebSocket endpoints for real-time features
- Create unit tests for Elysia instances
- Deploy Elysia servers to production
## Quick Start
Quick scaffold:
```bash
bun create elysia app
```
### Basic Server
```typescript
import { Elysia, t, status } from 'elysia'
const app = new Elysia()
.get('/', () => 'Hello World')
.post('/user', ({ body }) => body, {
body: t.Object({
name: t.String(),
age: t.Number()
})
})
.get('/id/:id', ({ params: { id } }) => {
if(id > 1_000_000) return status(404, 'Not Found')
return id
}, {
params: t.Object({
id: t.Number({
minimum: 1
})
}),
response: {
200: t.Number(),
404: t.Literal('Not Found')
}
})
.listen(3000)
```
## Basic Usage
### HTTP Methods
```typescript
import { Elysia } from 'elysia'
new Elysia()
.get('/', 'GET')
.post('/', 'POST')
.put('/', 'PUT')
.patch('/', 'PATCH')
.delete('/', 'DELETE')
.options('/', 'OPTIONS')
.head('/', 'HEAD')
```
### Path Parameters
```typescript
.get('/user/:id', ({ params: { id } }) => id)
.get('/post/:id/:slug', ({ params }) => params)
```
### Query Parameters
```typescript
.get('/search', ({ query }) => query.q)
// GET /search?q=elysia → "elysia"
```
### Request Body
```typescript
.post('/user', ({ body }) => body)
```
### Headers
```typescript
.get('/', ({ headers }) => headers.authorization)
```
## TypeBox Validation
### Basic Types
```typescript
import { Elysia, t } from 'elysia'
.post('/user', ({ body }) => body, {
body: t.Object({
name: t.String(),
age: t.Number(),
email: t.String({ format: 'email' }),
website: t.Optional(t.String({ format: 'uri' }))
})
})
```
### Nested Objects
```typescript
body: t.Object({
user: t.Object({
name: t.String(),
address: t.Object({
street: t.String(),
city: t.String()
})
})
})
```
### Arrays
```typescript
body: t.Object({
tags: t.Array(t.String()),
users: t.Array(t.Object({
id: t.String(),
name: t.String()
}))
})
```
### File Upload
```typescript
.post('/upload', ({ body }) => body.file, {
body: t.Object({
file: t.File({
type: 'image', // image/* mime types
maxSize: '5m' // 5 megabytes
}),
files: t.Files({ // Multiple files
type: ['image/png', 'image/jpeg']
})
})
})
```
### Response Validation
```typescript
.get('/user/:id', ({ params: { id } }) => ({
id,
name: 'John',
email: 'john@example.com'
}), {
params: t.Object({
id: t.Number()
}),
response: {
200: t.Object({
id: t.Number(),
name: t.String(),
email: t.String()
}),
404: t.String()
}
})
```
## Standard Schema (Zod, Valibot, ArkType)
### Zod
```typescript
import { z } from 'zod'
.post('/user', ({ body }) => body, {
body: z.object({
name: z.string(),
age: z.number().min(0),
email: z.string().email()
})
})
```
## Error Handling
```typescript
.get('/user/:id', ({ params: { id }, status }) => {
const user = findUser(id)
if (!user) {
return status(404, 'User not found')
}
return user
})
```
## Guards (Apply to Multiple Routes)
```typescript
.guard({
params: t.Object({
id: t.Number()
})
}, app => app
.get('/user/:id', ({ params: { id } }) => id)
.delete('/user/:id', ({ params: { id } }) => id)
)
```
## Macro
```typescript
.macro({
hi: (word: string) => ({
beforeHandle() { console.log(word) }
})
})
.get('/', () => 'hi', { hi: 'Elysia' })
```
### Project Structure (Recommended)
Elysia takes an unopinionated approach but based on user request. But without any specific preference, we recommend a feature-based and domain driven folder structure where each feature has its own folder containing controllers, services, and models.
```
src/
├── index.ts # Main server entry
├── modules/
│ ├── auth/
│ │ ├── index.ts # Auth routes (Elysia instance)
│ │ ├── service.ts # Business logic
│ │ └── model.ts # TypeBox schemas/DTOs
│ └── user/
│ ├── index.ts
│ ├── service.ts
│ └── model.ts
└── plugins/
└── custom.ts
public/ # Static files (if using static plugin)
test/ # Unit tests
```
Each file has its own responsibility as follows:
- **Controller (index.ts)**: Handle HTTP routing, request validation, and cookie.
- **Service (service.ts)**: Handle business logic, decoupled from Elysia controller if possible.
- **Model (model.ts)**: Define the data structure and validation for the request and response.
## Best Practice
Elysia is unopinionated on design pattern, but if not provided, we can relies on MVC pattern pair with feature based folder structure.
- Controller:
- Prefers Elysia as a controller for HTTP dependant controller
- For non HTTP dependent, prefers service instead unless explicitly asked
- Use `onError` to handle local custom errors
- Register Model to Elysia instance via `Elysia.models({ ...models })` and prefix model by namespace `Elysia.prefix('model', 'Namespace.')
- Prefers Reference Model by name provided by Elysia instead of using an actual `Model.name`
- Service:
- Prefers class (or abstract class if possible)
- Prefers interface/type derive from `Model`
- Return `status` (`import { status } from 'elysia'`) for error
- Prefers `return Error` instead of `throw Error`
- Models:
- Always export validation model and type of validation model
- Custom Error should be in contains in Model
## Elysia Key Concept
Elysia has a every important concepts/rules to understand before use.
## Encapsulation - Isolates by Default
Lifecycles (hooks, middleware) **don't leak** between instances unless scoped.
**Scope levels:**
- `local` (default) - current instance + descendants
- `scoped` - parent + current + descendants
- `global` - all instances
```ts
.onBeforeHandle(() => {}) // only local instance
.onBeforeHandle({ as: 'global' }, () => {}) // exports to all
```
## Method Chaining - Required for Types
**Must chain**. Each method returns new type reference.
❌ Don't:
```ts
const app = new Elysia()
app.state('build', 1) // loses type
app.get('/', ({ store }) => store.build) // build doesn't exists
```
✅ Do:
```ts
new Elysia()
.state('build', 1)
.get('/', ({ store }) => store.build)
```
## Explicit Dependencies
Each instance independent. **Declare what you use.**
```ts
const auth = new Elysia()
.decorate('Auth', Auth)
.model(Auth.models)
new Elysia()
.get('/', ({ Auth }) => Auth.getProfile()) // Auth doesn't exists
new Elysia()
.use(auth) // must declare
.get('/', ({ Auth }) => Auth.getProfile())
```
**Global scope when:**
- No types added (cors, helmet)
- Global lifecycle (logging, tracing)
**Explicit when:**
- Adds types (state, models)
- Business logic (auth, db)
## Deduplication
Plugins re-execute unless named:
```ts
new Elysia() // rerun on `.use`
new Elysia({ name: 'ip' }) // runs once across all instances
```
## Order Matters
Events apply to routes **registered after** them.
```ts
.onBeforeHandle(() => console.log('1'))
.get('/', () => 'hi') // has hook
.onBeforeHandle(() => console.log('2')) // doesn't affect '/'
```
## Type Inference
**Inline functions only** for accurate types.
For controllers, destructure in inline wrapper:
```ts
.post('/', ({ body }) => Controller.greet(body), {
body: t.Object({ name: t.String() })
})
```
Get type from schema:
```ts
type MyType = typeof MyType.static
```
## Reference Model
Model can be reference by name, especially great for documenting an API
```ts
new Elysia()
.model({
book: t.Object({
name: t.String()
})
})
.post('/', ({ body }) => body.name, {
body: 'book'
})
```
Model can be renamed by using `.prefix` / `.suffix`
```ts
new Elysia()
.model({
book: t.Object({
name: t.String()
})
})
.prefix('model', 'Namespace')
.post('/', ({ body }) => body.name, {
body: 'Namespace.Book'
})
```
Once `prefix`, model name will be capitalized by default.
## Technical Terms
The following are technical terms that is use for Elysia:
- `OpenAPI Type Gen` - function name `fromTypes` from `@elysiajs/openapi` for generating OpenAPI from types, see `plugins/openapi.md`
- `Eden`, `Eden Treaty` - e2e type safe RPC client for share type from backend to frontend

# AI SDK Integration
## What It Is
Seamless integration with Vercel AI SDK via response streaming.
## Response Streaming
Return `ReadableStream` or `Response` directly:
```typescript
import { streamText } from 'ai'
import { openai } from '@ai-sdk/openai'
new Elysia().get('/', () => {
const stream = streamText({
model: openai('gpt-5'),
system: 'You are Yae Miko from Genshin Impact',
prompt: 'Hi! How are you doing?'
})
return stream.textStream // ReadableStream
// or
return stream.toUIMessageStream() // UI Message Stream
})
```
Elysia auto-handles stream.
## Server-Sent Events
Wrap `ReadableStream` with `sse`:
```typescript
import { sse } from 'elysia'
.get('/', () => {
const stream = streamText({ /* ... */ })
return sse(stream.textStream)
// or
return sse(stream.toUIMessageStream())
})
```
Each chunk → SSE.
## As Response
Return stream directly (no Eden type safety):
```typescript
.get('/', () => {
const stream = streamText({ /* ... */ })
return stream.toTextStreamResponse()
// or
return stream.toUIMessageStreamResponse() // Uses SSE
})
```
## Manual Streaming
Generator function for control:
```typescript
import { sse } from 'elysia'
.get('/', async function* () {
const stream = streamText({ /* ... */ })
for await (const data of stream.textStream)
yield sse({ data, event: 'message' })
yield sse({ event: 'done' })
})
```
## Fetch for Unsupported Models
Direct fetch with streaming proxy:
```typescript
.get('/', () => {
return fetch('https://api.openai.com/v1/chat/completions', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
Authorization: `Bearer ${process.env.OPENAI_API_KEY}`
},
body: JSON.stringify({
model: 'gpt-5',
stream: true,
messages: [
{ role: 'system', content: 'You are Yae Miko' },
{ role: 'user', content: 'Hi! How are you doing?' }
]
})
})
})
```
Elysia auto-proxies fetch response with streaming.

# Astro Integration - SKILLS.md
## What It Is
Run Elysia on Astro via Astro Endpoint.
## Setup
1. Set output to server:
```javascript
// astro.config.mjs
export default defineConfig({
output: 'server'
})
```
2. Create `pages/[...slugs].ts`
3. Define Elysia server + export handlers:
```typescript
// pages/[...slugs].ts
import { Elysia, t } from 'elysia'
const app = new Elysia()
.get('/api', () => 'hi')
.post('/api', ({ body }) => body, {
body: t.Object({ name: t.String() })
})
const handle = ({ request }: { request: Request }) => app.handle(request)
export const GET = handle
export const POST = handle
```
WinterCG compliance - works normally.
Recommended: Run Astro on Bun (Elysia designed for Bun).
## Prefix for Non-Root
If placed in `pages/api/[...slugs].ts`, set prefix:
```typescript
// pages/api/[...slugs].ts
const app = new Elysia({ prefix: '/api' })
.get('/', () => 'hi')
const handle = ({ request }: { request: Request }) => app.handle(request)
export const GET = handle
export const POST = handle
```
Ensures routing works in any location.
## Benefits
Co-location of frontend + backend. End-to-end type safety with Eden.
## pnpm
Manual install:
```bash
pnpm add @sinclair/typebox openapi-types
```

# Better Auth Integration
Elysia + Better Auth integration guide
## What It Is
Framework-agnostic TypeScript auth/authz. Comprehensive features + plugin ecosystem.
## Setup
```typescript
import { betterAuth } from 'better-auth'
import { Pool } from 'pg'
export const auth = betterAuth({
database: new Pool()
})
```
## Handler Mounting
```typescript
import { auth } from './auth'
new Elysia()
.mount(auth.handler) // http://localhost:3000/api/auth
.listen(3000)
```
### Custom Endpoint
```typescript
// Mount with prefix
.mount('/auth', auth.handler) // http://localhost:3000/auth/api/auth
// Customize basePath
export const auth = betterAuth({
basePath: '/api' // http://localhost:3000/auth/api
})
```
Cannot set `basePath` to empty or `/`.
## OpenAPI Integration
Extract docs from Better Auth:
```typescript
import { openAPI } from 'better-auth/plugins'
let _schema: ReturnType<typeof auth.api.generateOpenAPISchema>
const getSchema = async () => (_schema ??= auth.api.generateOpenAPISchema())
export const OpenAPI = {
getPaths: (prefix = '/auth/api') =>
getSchema().then(({ paths }) => {
const reference: typeof paths = Object.create(null)
for (const path of Object.keys(paths)) {
const key = prefix + path
reference[key] = paths[path]
for (const method of Object.keys(paths[path])) {
const operation = (reference[key] as any)[method]
operation.tags = ['Better Auth']
}
}
return reference
}) as Promise<any>,
components: getSchema().then(({ components }) => components) as Promise<any>
} as const
```
Apply to Elysia:
```typescript
new Elysia().use(openapi({
documentation: {
components: await OpenAPI.components,
paths: await OpenAPI.getPaths()
}
}))
```
## CORS
```typescript
import { cors } from '@elysiajs/cors'
new Elysia()
.use(cors({
origin: 'http://localhost:3001',
methods: ['GET', 'POST', 'PUT', 'DELETE', 'OPTIONS'],
credentials: true,
allowedHeaders: ['Content-Type', 'Authorization']
}))
.mount(auth.handler)
```
## Macro for Auth
Use macro + resolve for session/user:
```typescript
const betterAuth = new Elysia({ name: 'better-auth' })
.mount(auth.handler)
.macro({
auth: {
async resolve({ status, request: { headers } }) {
const session = await auth.api.getSession({ headers })
if (!session) return status(401)
return {
user: session.user,
session: session.session
}
}
}
})
new Elysia()
.use(betterAuth)
.get('/user', ({ user }) => user, { auth: true })
```
Access `user` and `session` in all routes.

# Cloudflare Worker Integration
## What It Is
**Experimental** Cloudflare Worker adapter for Elysia.
## Setup
1. Install Wrangler:
```bash
wrangler init elysia-on-cloudflare
```
2. Apply adapter + compile:
```typescript
import { Elysia } from 'elysia'
import { CloudflareAdapter } from 'elysia/adapter/cloudflare-worker'
export default new Elysia({
adapter: CloudflareAdapter
})
.get('/', () => 'Hello Cloudflare Worker!')
.compile() // Required
```
3. Set compatibility date (min `2025-06-01`):
```json
// wrangler.json
{
"name": "elysia-on-cloudflare",
"main": "src/index.ts",
"compatibility_date": "2025-06-01"
}
```
4. Dev server:
```bash
wrangler dev
# http://localhost:8787
```
No `nodejs_compat` flag needed.
## Limitations
1. `Elysia.file` + Static Plugin don't work (no `fs` module)
2. OpenAPI Type Gen doesn't work (no `fs` module)
3. Cannot define Response before server start
4. Cannot inline values:
```typescript
// ❌ Throws error
.get('/', 'Hello Elysia')
// ✅ Works
.get('/', () => 'Hello Elysia')
```
## Static Files
Use Cloudflare's built-in static serving:
```json
// wrangler.json
{
"assets": { "directory": "public" }
}
```
Structure:
```
├─ public
│ ├─ kyuukurarin.mp4
│ └─ static/mika.webp
```
Access:
- `http://localhost:8787/kyuukurarin.mp4`
- `http://localhost:8787/static/mika.webp`
## Binding
Import env from `cloudflare:workers`:
```typescript
import { env } from 'cloudflare:workers'
export default new Elysia({ adapter: CloudflareAdapter })
.get('/', () => `Hello ${await env.KV.get('my-key')}`)
.compile()
```
## AoT Compilation
As of Elysia 1.4.7, AoT works with Cloudflare Worker. Drop `aot: false` flag.
Cloudflare now supports Function compilation during startup.
## pnpm
Manual install:
```bash
pnpm add @sinclair/typebox openapi-types
```
