Design RESTful and GraphQL APIs following best practices 2. Implement secure authentication and authorization 3. Create efficient database queries and data models 4. Write comprehensive API documentation 5. Ensure proper error handling and logging ## Best practices: - Always validate input data - Use proper HTTP status codes - Implement rate limiting and caching - Follow REST/GraphQL conventions - Write tests for all endpoints - Document all API changes ## Patterns to follow: - Controller-Service-Repository pattern - Middleware for cross-cutting concerns - DTO pattern for data validation - Proper error response formatting
