+# 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.

+# 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.

+# 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.
+

+Copy as-is for simplified usage:
+```typescript

+
+Usage:

+
+// ⚠️ 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).

+// 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.

+# Node.js Integration
+Run Elysia on Node.js
+
+## What It Is
+Runtime adapter to run Elysia on Node.js.
+
+## Installation
+```bash
+bun add elysia @elysiajs/node
+```
+
+## Setup
+Apply node adapter:
+```typescript
+import { Elysia } from 'elysia'
+import { node } from '@elysiajs/node'
+
+const app = new Elysia({ adapter: node() })
+  .get('/', () => 'Hello Elysia')
+  .listen(3000)
+```
+
+## Additional Setup (Recommended)
+Install `tsx` for hot-reload:
+```bash
+bun add -d tsx @types/node typescript
+```
+
+Scripts in `package.json`:
+```json
+{
+  "scripts": {
+    "dev": "tsx watch src/index.ts",
+    "build": "tsc src/index.ts --outDir dist",
+    "start": "NODE_ENV=production node dist/index.js"
+  }
+}
+```
+
+- **dev**: Hot-reload dev mode
+- **build**: Production build
+- **start**: Production server
+
+Create `tsconfig.json`:
+```bash
+tsc --init
+```
+
+Update strict mode:
+```json
+{
+  "compilerOptions": {
+    "strict": true
+  }
+}
+```
+
+Provides hot-reload + JSX support similar to `bun dev`.

+# Nuxt Integration
+
+## What It Is
+Community plugin `nuxt-elysia` for Nuxt API routes with Eden Treaty.
+
+## Installation
+```bash
+bun add elysia @elysiajs/eden
+bun add -d nuxt-elysia
+```
+
+## Setup
+1. Add to Nuxt config:
+```typescript
+export default defineNuxtConfig({
+  modules: ['nuxt-elysia']
+})
+```
+
+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`.
+
+See [nuxt-elysia](https://github.com/tkesgar/nuxt-elysia) for more config.

+# 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)
+```
+
+Reuses DB schema in Elysia validation models.

+# 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">

+            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',

+  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 }) => {

+# SvelteKit Integration
+
+## What It Is
+Run Elysia on SvelteKit server routes.
+
+## Setup
+1. Create `src/routes/[...slugs]/+server.ts`
+2. Define Elysia server
+3. Export fallback handler:
+```typescript
+// src/routes/[...slugs]/+server.ts
+import { Elysia, t } from 'elysia'
+
+const app = new Elysia()
+  .get('/', 'hello SvelteKit')
+  .post('/', ({ body }) => body, {
+    body: t.Object({ name: t.String() })
+  })
+
+interface WithRequest {
+  request: Request
+}
+
+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
+import { Elysia, t } from 'elysia'
+
+const app = new Elysia({ prefix: '/api' })
+  .get('/', () => 'hi')
+  .post('/', ({ body }) => body, {
+    body: t.Object({ name: t.String() })
+  })
+
+type RequestHandler = (v: { request: Request }) => Response | Promise<Response>
+
+export const fallback: RequestHandler = ({ request }) => app.handle(request)
+```
+
+Ensures routing works in any location.

+# 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({
+  prefix: '/api'
+}).get('/', 'Hello 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()
+  })
+  
+  return response?.data
+}
