Express.js Routing
Express.js Routing is a core feature of the Express.js web application framework for Node.js that defines how an application responds to client requests to specific endpoints (URIs) and HTTP methods (GET, POST, etc.). It uses a simple, declarative syntax to map URL patterns and HTTP verbs to handler functions, enabling developers to structure server-side logic for handling different routes in web applications, APIs, and microservices.
Developers should learn Express.js Routing when building web servers or RESTful APIs with Node.js, as it provides a clean, organized way to handle HTTP requests and define application endpoints. It is essential for creating scalable server-side applications, such as e-commerce sites, content management systems, or backend services, where routing logic separates concerns and improves code maintainability.
