Backend API

RESTful API design uses standard HTTP methods (GET, POST, PUT, DELETE) with consistent naming conventions and appropriate status codes. This ensures predictable client interactions, reduces integration complexity, and establishes a foundation for scalable backend services.

Organize routes by resource, implement controllers to handle requests, use nested resources for relationships, and apply naming conventions consistently. This approach simplifies maintenance, enables team collaboration, and supports long-term scalability as your API grows.

Add query parameters to endpoints for filtering by category or other attributes, and use limit/offset or page/pageSize for pagination. This enables clients to retrieve data efficiently, reduces payload size, and improves performance across backend services.

API versioning maintains backward compatibility during updates, while rate limiting controls request volume and prevents abuse. Together they ensure stability, manageability, and predictable performance for client applications.

Yes. Resource transformers format data consistently before returning it to clients, while nested resources represent related entities in a single endpoint. Both patterns improve response clarity and simplify client-side data handling.
