Basic Routing

In web development, routing refers to defining how a server handles incoming client requests based on the requested URL and HTTP method. It serves as a blueprint for directing requests to the appropriate responses, enabling the server to serve different purposes dynamically. For example, routing can be used to display a homepage, retrieve or submit data, handle user authentication, or show an error message for unknown routes.

By implementing routing, a server can map specific URLs or request patterns to dedicated logic, making it flexible and capable of handling various client needs. This approach is foundational for building interactive web applications and APIs, as it allows developers to create tailored responses for different endpoints, such as /about, /api/data, or /404.

Node.js’s event-driven, non-blocking architecture makes it especially effective for handling multiple routes in a single server. In this lesson, we’ll create a basic server that serves different responses depending on the requested URL. ...
