Custom Endpoints

Create custom endpoints with advanced configurations and patterns.

Custom Paths

Define custom paths beyond CRUD:

endpoints:
  - path: /todos/featured
    method: GET
    handler: handlers/getFeaturedTodos
    response:
      type: TodoArray
  
  - path: /todos/:id/comments
    method: GET
    handler: handlers/getTodoComments
    response:
      type: CommentArray

Multiple Methods

Handle multiple methods on the same path:

endpoints:
  - path: /todos/:id/archive
    method: POST
    handler: handlers/archiveTodo
  
  - path: /todos/:id/archive
    method: DELETE
    handler: handlers/unarchiveTodo

Complex Query Parameters

Define complex query schemas:

endpoints:
  - path: /products
    method: GET
    query:
      category:
        type: string
        enum: [electronics, clothing, books]
      priceMin:
        type: number
        minimum: 0
      priceMax:
        type: number
        minimum: 0
      sortBy:
        type: string
        enum: [price, name, date]
        default: date
      sortOrder:
        type: string
        enum: [asc, desc]
        default: desc
    handler: handlers/searchProducts

Request Validation

Validate request bodies:

endpoints:
  - path: /users
    method: POST
    body:
      type: object
      required: [email, password]
      properties:
        email:
          type: string
          format: email
        password:
          type: string
          minLength: 8
          pattern: '^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)'
    handler: handlers/createUser

Response Types

Use different response types:

endpoints:
  - path: /todos
    method: GET
    response:
      type: object
      properties:
        todos:
          type: array
          items:
            $ref: "#/schemas/Todo"
        total:
          type: number
        page:
          type: number

Middleware-like Handlers

Chain handlers for middleware-like behavior:

// src/handlers/withAuth.ts
export async function withAuth(
  context: HandlerContext,
  next: () => Promise<any>
) {
  if (!context.auth.user) {
    context.response.status(401);
    return { error: 'Unauthorized' };
  }
  
  return next();
}

// src/handlers/getProfile.ts
export async function getProfile(context: HandlerContext) {
  // User is guaranteed to be authenticated
  return context.auth.user;
}

File Uploads

Handle file uploads:

endpoints:
  - path: /upload
    method: POST
    handler: handlers/uploadFile

export async function uploadFile(context: HandlerContext) {
  const file = context.request.files?.file;
  
  if (!file) {
    context.response.status(400);
    return { error: 'No file provided' };
  }
  
  // Process file...
  return { success: true, url: fileUrl };
}

Webhooks

Create webhook endpoints:

endpoints:
  - path: /webhooks/stripe
    method: POST
    handler: handlers/stripeWebhook
    auth:
      required: false  # Webhooks use signature verification

Rate Limiting

Configure rate limiting:

endpoints:
  - path: /api/expensive-operation
    method: POST
    handler: handlers/expensiveOperation
    rateLimit:
      max: 10
      window: 60000  # per minute

CORS

Configure CORS per endpoint:

endpoints:
  - path: /api/public
    method: GET
    handler: handlers/publicData
    cors:
      origin: '*'
      methods: [GET, OPTIONS]
