Can You Create an HTTPS Web Server With NodeJS?


Heather Bennett

In today’s digital world, security is of utmost importance. As a website owner, it is crucial to ensure that your users’ data is protected while they browse your site.

One way to achieve this is by using HTTPS, which provides a secure connection between the user’s browser and the web server. In this tutorial, we will explore how you can create an HTTPS web server with Node.js.

What is Node.js?

Node.js is an open-source JavaScript runtime that allows you to run JavaScript code outside of a web browser. It uses an event-driven, non-blocking I/O model, making it lightweight and efficient for building scalable network applications. With its rich ecosystem of packages and modules, Node.js has gained popularity among developers for various use cases.

Setting Up the Project

To get started, make sure you have Node.js installed on your machine. You can download the latest version from the official website and follow the installation instructions for your operating system.

Once you have Node.js installed, open your terminal or command prompt and create a new directory for your project. Navigate to the project directory using the `cd` command:

$ mkdir https-web-server
$ cd https-web-server

Initializing a New Node.js Project

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

$ npm init -y

This will create a new `package.json` file in your project directory which will keep track of your project dependencies.

Installing Required Packages

To create an HTTPS web server with Node.js, we need to install two packages: `express` and `https`. Express is a popular web framework for building web applications in Node.js, while HTTPS provides functionality for creating secure servers.

To install these packages, run the following command:

$ npm install express https

Creating the HTTPS Server

Now that we have our project set up and the required packages installed, let’s create the HTTPS server.

First, create a new file called `server.js` in your project directory. Open the file in your preferred code editor and add the following code:

const express = require('express');
const https = require('https');
const fs = require('fs');

const app = express();

// Your server logic here

const options = {
key: fs.readFileSync('path/to/private.key'),
cert: fs.readFileSync('path/to/certificate.crt')

https.createServer(options, app).listen(443);

console.log('Server running on port 443');

In the above code, we import the necessary modules: `express`, `https`, and `fs` (file system). We then create an instance of Express and define our server logic.

Next, we specify the path to your private key and certificate files. Make sure to replace `’path/to/private.key’` and `’path/to/certificate.crt’` with the actual paths to your files.

Finally, we create an HTTPS server using the `createServer` method from the `https` module, passing in our options object and Express app. We listen on port 443, which is the default port for HTTPS traffic.

Testing the Server

To test our HTTPS server, save the changes to `server.js` and run it using Node.js:

$ node server.js

If there are no errors, you should see a message indicating that the server is running on port 443.

Open your web browser and visit `https://localhost`. You should see a security warning since we are using a self-signed certificate. Click on “Advanced” or “Proceed” (depending on your browser) to proceed to the site.

Congratulations! You have successfully created an HTTPS web server with Node. Remember, in a production environment, you would typically use a trusted certificate from a certificate authority (CA) to avoid security warnings.


In this tutorial, we explored how to create an HTTPS web server with Node. We learned about Node.js and its benefits, set up our project, installed the necessary packages, and created the HTTPS server using Express and the HTTPS module. We also tested our server and discussed the importance of using trusted certificates in a production environment.

By following this tutorial, you can now enhance the security of your web applications by providing a secure connection for your users. Stay safe and keep learning!
