Can You Create an HTTPS Web Server With Node Js?


Scott Campbell

Creating an HTTPS web server with Node.js is a relatively straightforward process that can provide an added layer of security to your web applications. In this tutorial, we will explore how to set up a secure HTTPS server using the built-in https module in Node.js.


Before diving into the implementation, make sure you have the following prerequisites:

  • Node.js: Ensure that you have Node.js installed on your machine. You can download it from the official website and follow the installation instructions.
  • Basic knowledge of Node.js: Familiarity with JavaScript and basic concepts of Node.js will be helpful.
  • A domain name: To set up an HTTPS server, you will need a domain name. If you don’t have one, you can use a local development domain or create a self-signed SSL certificate for testing purposes.

Setting Up the HTTPS Server

To create an HTTPS server in Node.js, we need to use the https.createServer() method provided by the https module. This method takes an options object as its parameter and returns an instance of a secure HTTP server.

The options object should include the necessary SSL certificate and private key files required for creating HTTPS connections. Here’s an example of how you can set up your options object:

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

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

In this example, we are using the built-in fs module to read the SSL certificate and private key files from the file system. Make sure to replace /path/to/private/key.pem and /path/to/certificate.pem with the actual file paths of your SSL certificate and private key.

Once we have our options object ready, we can create the HTTPS server as follows:

const server = https.createServer(options, (req, res) => {
  // Handle incoming requests

In the above code snippet, we pass our options object as the first parameter to https.createServer(). The second parameter is a callback function that will be invoked whenever an HTTPS request is made to our server. You can add your own logic inside this callback function to handle incoming requests.

Starting the HTTPS Server

Now that our HTTPS server is set up, we need to start it and listen for incoming connections. We can do this by calling the server.listen() method:

const port = 443;

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

In this example, we are listening on port 443, which is the default port for HTTPS connections. Make sure that this port is not already in use by another application on your machine. You can change the port number if needed.

Testing the HTTPS Server

To test our newly created HTTPS server, open your favorite web browser and enter your domain name or local development domain with an “https://” prefix. If everything is set up correctly, you should see a secure connection icon (usually a lock) in your browser’s address bar.

If you are using a self-signed SSL certificate for testing purposes, your browser may display a warning about the certificate being untrusted. You can safely proceed by accepting the certificate or adding it as an exception in your browser’s settings.


Creating an HTTPS web server with Node.js is a crucial step in securing your web applications. By following the steps outlined in this tutorial, you should now have a functioning HTTPS server that can handle secure connections. Remember to obtain a valid SSL certificate from a trusted certificate authority when deploying your application to production.

Happy coding!
