Can You Create an HTTP Web Server With NodeJS?

Node.js is a powerful JavaScript runtime built on Chrome’s V8 engine. It allows you to build scalable and high-performance network applications.

One of the most common use cases of Node.js is creating web servers. In this tutorial, we will explore how to create an HTTP web server using Node.js.


Before you begin:

  • Make sure you have Node.js installed on your machine. You can download it from the official website:
  • Basic knowledge of JavaScript and web development concepts will be beneficial.

Setting Up the Project

To start, create a new directory for your project and navigate into it using the command line interface:

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

Next, initialize a new Node.js project by running the following command:

$ npm init -y

This command creates a package.json file which tracks the dependencies and metadata of your project.

Installing Dependencies

We need to install the ‘http’ module, which comes bundled with Node.js, to create our web server. Run the following command:

$ npm install http

Create an HTTP Server

In your project directory, create a new file named server.js. This will be our main file where we will write our server logic.

$ touch server.js

Open server.js in your favorite text editor and add the following code:

// Import the 'http' module
const http = require('http');

// Define the hostname and port number
const hostname = 'localhost';
const port = 3000;

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

// Start the server
server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);

This code imports the ‘http’ module, sets up the hostname and port number for our server, creates a server object using createServer(), and starts listening for incoming requests on the specified port. It responds with a simple “Hello, World!” message.

Start the Server

To start your web server, run the following command in your project directory:

$ node server.js

You should see a message in the console indicating that your server is running at http://localhost:3000/.

Testing the Server

Open your favorite web browser and navigate to http://localhost:3000/. You should see the “Hello, World!” message displayed.


You have successfully created an HTTP web server using Node. This is just a basic example, but you can extend it to handle different routes, serve HTML pages, or interact with databases.

Remember to always handle errors and sanitize user input when building production-ready web servers. Node.js provides a rich ecosystem of modules and frameworks that can help you with these tasks.

Happy coding!
