Creating an HTTP Web Server With Node.js

Node.js is a popular runtime environment that allows developers to build server-side applications using JavaScript. One of the key features of Node.js is its ability to create web servers and handle HTTP requests. In this tutorial, we will explore how to create an HTTP web server with Node.js.

Setting Up the Environment

Before we dive into creating the web server, ensure that you have Node.js installed on your machine. You can download and install it from the official Node.js website.

Once you have Node.js installed, open your favorite code editor and create a new folder for your project. Navigate to the project folder in your terminal or command prompt.

Initializing a New Node.js Project

To initialize a new Node.js project, run the following command in your terminal:

  • Step 1: Open your terminal or command prompt.
  • Step 2: Navigate to your project folder.
  • Step 3: Run the following command: npm init.

This command will prompt you to enter various details about your project, such as its name, version, description, and entry point. You can press enter to accept the default values for most of these options.

Create a Basic Web Server

To create a basic web server with Node.js, we need to use the built-in ‘http’ module. The ‘http’ module provides functionality for creating an HTTP server and handling incoming requests.

Create a new file named ‘server.js’ in your project folder and add the following code:

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 on port ${port}`);

In the code above, we first import the ‘http’ module using the ‘require’ function. We then create a new server using the ‘createServer’ method provided by the ‘http’ module. This method takes a callback function as an argument, which will be invoked whenever a request is made to the server.

Inside the callback function, we set the status code of the response to 200, indicating a successful response. We also set the ‘Content-Type’ header to ‘text/plain’, specifying that we are sending plain text as the response body.

Finally, we send the response with the message ‘Hello, World!’ using the ‘end’ method.

We also define a variable named ‘port’ and set it to 3000. This is the port on which our server will listen for incoming requests.

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

  • Step 1: Open your terminal or command prompt.
  • Step 3: Run the following command: node server.js.

You should see a message in your terminal indicating that the server is running on port 3000.

Testing Your Web Server

To test your web server, open a web browser and navigate to ‘http://localhost:3000’. You should see the message ‘Hello, World!’ displayed in your browser.

Congratulations! You have successfully created an HTTP web server with Node. This is just the beginning, and you can now explore more advanced features and functionalities that Node.js offers for building robust web applications.


In this tutorial, we learned how to create a basic HTTP web server with Node. We covered setting up the environment, initializing a new Node.js project, creating a basic server using the ‘http’ module, and testing our web server. Node.js provides a powerful platform for building scalable and efficient web servers, allowing developers to leverage their JavaScript skills on the server-side as well.
