Express Route Template

This template helps you create robust Express.js routes with proper middleware, validation, error handling, and security practices. It follows RESTful conventions and includes comprehensive request/response handling.

Sample Prompt

Create Express.js routes for a blog API:
- GET /api/posts - list posts with pagination and filtering
- GET /api/posts/:id - get single post with comments
- POST /api/posts - create new post (authenticated)
- PUT /api/posts/:id - update post (authenticated, author only)
- DELETE /api/posts/:id - delete post (authenticated, author only)

Include middleware for authentication, validation, and error handling.

What This Template Covers

  • RESTful route design with proper HTTP methods and status codes
  • Middleware integration for authentication, validation, and logging
  • Request validation using express-validator or Joi
  • Error handling with custom error classes and middleware
  • Security practices including rate limiting and input sanitization
  • Documentation with clear route descriptions and examples

Best Practices

  1. Use proper HTTP status codes for different response types
  2. Implement comprehensive validation for all inputs
  3. Add authentication and authorization where needed
  4. Include rate limiting to prevent abuse
  5. Use middleware consistently for cross-cutting concerns
  6. Handle errors gracefully with meaningful messages
  7. Document all routes with clear examples
  8. Follow RESTful conventions for predictable APIs

When to Use This Template

  • Building REST APIs with Express.js
  • Creating CRUD operations for resources
  • Implementing authentication-protected routes
  • Adding validation and error handling to existing routes
  • Standardizing API route structure across projects
