Backend API

Design and implement RESTful API endpoints following industry best practices. Use this skill when creating API routes, controllers, or endpoint handlers. Apply when working on files like routes.ts, api/*.ts, controllers/*.ts, or any server-side endpoint definitions. Essential for implementing CRUD operations, handling HTTP methods (GET, POST, PUT, PATCH, DELETE), designing URL structures, implementing versioning, setting up query parameters for filtering/sorting/pagination, and returning proper HTTP status codes.
