An Express route is a mechanism in the Express.js framework for handling incoming HTTP requests and defining how the server should respond to those requests.
❓ How is it used?
Express routes are defined using HTTP methods (GET, POST, PUT, DELETE, etc.) and URL patterns. Each route consists of a combination of an HTTP method, a URL pattern, and a callback function that gets executed when the route is matched.
Routes are created using the app.METHOD() functions provided by Express, where METHOD is the HTTP method (e.g., app.get(), app.post(), app.put(), app.delete()).
Inside the callback function, developers can define the logic for handling the request, accessing request parameters, processing data, and sending a response back to the client.
Why is it needed?
Express routes provide a structured way to define the behavior of a web server and handle different types of requests.
They help organize the codebase by separating different functionalities into individual route handlers, making the codebase easier to understand, maintain, and scale.
Express routes allow developers to create RESTful APIs by mapping HTTP methods to CRUD (Create, Read, Update, Delete) operations on resources.
With Express routes, developers can implement complex routing logic, including route parameters, query parameters, middleware functions, and route chaining, to create flexible and powerful web applications.
