+# 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)
