Node.js is a JavaScript runtime that allows you to build server-side applications with JavaScript. In this guide, we'll walk you through the steps to create a simple HTTP server using Node.js.

Step 1: Set Up the Project

First, open your terminal and create a new directory for your Node.js project. You can do this by running the following command:

This creates a new directory called node-server and navigates into it.

Step 2: Initialize the Project (Optional)

Before creating the server, it's a good idea to initialize a package.json file to keep track of your dependencies. Run this command to generate a package.json file:

This will create a default package.json file in your project directory, which you can later edit to add dependencies.

Step 3: Create the app.js File

Next, you'll create a new JavaScript file where you'll write the code for your Node.js server. In your terminal, run:

This command will create a new file named app.js.

Step 4: Write the Server Code

Open app.jsin your preferred text editor and add the following code to create a basic HTTP server.

To run this command app.js

output:

Explanation

👆 step 1: Import Node.js core module

step 2: creating server

step 3: handle incomming requests here..

step 4: listen for any incoming requests

step 5: console log

Output

app.js

var http = require("http");

var server = http.createServer(function (req, res) {

res.write("Hello World!");

res.end();

});

server.listen(5000);

console.log("Node.js web server at port 5000 is running..");
