Building RESTful APIs with Node.js and Express

Building RESTful APIs is a fundamental skill for full-stack developers. Let's explore how to create robust APIs with Node.js and Express. ## REST Principles REST (Representational State Transfer) is an architectural style that uses HTTP methods (GET, POST, PUT, DELETE) to perform CRUD operations on resources. ## Express Setup Express is a minimal and flexible Node.js framework that provides a robust set of features for building APIs. ## Route Organization Organize your routes logically, grouping related endpoints together. Use Express Router to modularize your route definitions. ## Error Handling Implement consistent error handling with proper HTTP status codes and meaningful error messages. ## Authentication Secure your API with authentication mechanisms like JWT (JSON Web Tokens) or OAuth 2.0. ## Documentation Document your API using tools like Swagger/OpenAPI to make it easy for other developers to understand and use your endpoints.
