Sure, here is a response with explanations for each step:

  1. First, you need to install Express by running the following command in your terminal:
npm install express

This command will install the Express framework in your project.

  1. Next, you will need to require the Express module in your JavaScript file:
const express = require('express');

This line of code will import the Express module into your file, allowing you to use its functionalities.

  1. Then, you can create an instance of the Express application by calling the express() function:
const app = express();

This line of code creates a new Express application, which can be used to define routes and handle HTTP requests.

  1. After that, you can define a route to handle incoming HTTP GET requests. For example:
app.get('/', (req, res) => {
  res.send('Hello, World!');
});

This code sets up a route that responds with "Hello, World!" when a GET request is made to the root URL.

  1. Finally, you can start the Express server by listening on a specific port:
const port = 3000;
app.listen(port, () => {
  console.log(`Server is running on port ${port}`);
});

This code starts the Express server and listens for incoming connections on the specified port (in this case, port 3000).

These are the basic steps to set up an Express application and define a simple route. Express is a powerful framework for building web applications and APIs, and these steps will help you get started with it.
