Creating an HTTP Web Server With Node.js

Node.js is a powerful platform that allows developers to build server-side applications using JavaScript. One of the key functionalities of Node.js is its ability to create web servers. In this tutorial, we will explore how to create an HTTP web server using Node.js.

Getting Started

To begin, make sure you have Node.js installed on your machine. You can download the latest version from the official Node.js website ( Once installed, open your favorite code editor and create a new file with a .js extension.

Importing Required Modules

In order to create an HTTP server, we need to import the built-in ‘http’ module provided by Node. This module provides all the necessary tools for handling HTTP requests and responses. To import the ‘http’ module, add the following line of code at the beginning of your file:

const http = require('http');

Creating Server

Now that we have imported the ‘http’ module, let’s create our server instance. We can do this by invoking the ‘createServer()’ method provided by the ‘http’ module. This method takes a callback function as an argument, which will be executed whenever a request is made to our server.

const server = http.createServer((req, res) => {
// Handle request here

Handling Requests

Inside our callback function, we can handle incoming requests and send back appropriate responses. For example, let’s send a simple “Hello World!” message as the response for every request:

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

Starting the Server

After creating the server, we need to start it and make it listen on a specific port. We can accomplish this by calling the ‘listen()’ method on our server instance. This method takes two arguments: the port number and an optional callback function.

const port = 3000;

server.listen(port, () => {
console.log(`Server running on port ${port}`);

Testing the Server

To test our server, open your favorite web browser and navigate to http://localhost:3000 (assuming you used port 3000). You should see the “Hello World!” message displayed in your browser.


Creating an HTTP web server with Node.js is simple yet powerful. With just a few lines of code, we can handle incoming requests and send back appropriate responses.

Node.js provides a wide range of additional features and tools for building robust web applications. So go ahead, experiment with different functionalities, and unleash the full potential of Node.js!
