Node.js makes it incredibly easy to create a basic web server. Here’s how you can do it in just a few lines of code:

Step 1: Set up your project

First, create a new directory for your project and navigate into it:

mkdir my-web-server
cd my-web-server

Step 2: Create the server file

Create a new file called server.js and open it in your favorite text editor.

Step 3: Write the server code

Here’s the basic code to create a web server:

const http = require('http');

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello, World!');
});

const port = 3000;
server.listen(port, () => {
  console.log(`Server running at http://localhost:${port}/`);
});

This code does the following: - Imports the built-in http module - Creates a server that responds with “Hello, World!” - Sets the server to listen on port 3000

Step 4: Run the server

Save the file and run it using Node.js:

node server.js

You should see the message “Server running at http://localhost:3000/" in your console.

Step 5: Test your server

Open a web browser and go to http://localhost:3000. You should see “Hello, World!” displayed.

Congratulations! You’ve created a simple web server using Node.js. This basic setup can be expanded to serve HTML files, handle different routes, and much more.
