How does express.default work?

express.default is a Node.js web framework that simplifies the process of building web applications by providing a set of features and tools for creating and managing routes, handling requests and responses, and more.

When express.default is used, a new application instance is created, which can be used to define routes and middleware. A route is a combination of an HTTP method and a URL path, which maps to a function that handles the request and sends a response. Middleware functions can be used to modify the request or response objects, or to perform other tasks such as logging or authentication.

express.default provides a range of methods for defining routes and middleware, including app.get, app.post, app.use, and more. These methods can be used to define routes and middleware functions, and to specify the behavior for handling incoming requests.

express.default also provides various other features and tools for working with requests and responses, such as handling JSON data, working with cookies and sessions, and using third-party middleware.

Overall, express.default provides a powerful and flexible way to build web applications in Node.js, making it easier to create complex and dynamic web applications.

const express = require("express");

// Create a new Express application instance
const app = express();

// Define a route handler for the root URL path
app.get("/", (req, res) => {
  res.send("Hello World!");
});

// Start the server on port 3000
app.listen(3000, () => {
  console.log("Server listening on port 3000");
});

In this example, we first import express.default as a module and create a new instance of the Express application using express(). We define a route handler using the get method, which handles GET requests to the root URL path '/'. This route handler simply sends a response of 'Hello World!' using the res.send method. Finally, we start the server listening on port 3000 using the listen method, and log a message to the console when the server is started. This example shows how express.default can be used to create a simple web server with a single route handler, but it can be extended and customized to handle a wide range of complex scenarios and use cases.
