How to Create an HTTPS Server with SSL Certificate in Node.js?

Creating an HTTPS Server in Node.js

In Node.js, establishing an HTTPS server involves utilizing the Express framework and the 'https' module. Here's a detailed response to the question:

Given an SSL key and certificate, how does one create an HTTPS service?

Solution:

The Express API documentation provides clear instructions on how to achieve this. Additionally, the following steps will assist you in creating a self-signed certificate:

var express = require('express');
var https = require('https');
var http = require('http');
var fs = require('fs');

// Import the certificate and key
const options = {
  key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
  cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem')
};

// Initialize the Express app
const app = express();

// Create HTTP and HTTPS servers
const httpsServer = https.createServer(options, app);
const httpServer = http.createServer(app);

// Set up the HTTP and HTTPS ports
httpsServer.listen(443);
httpServer.listen(80);

By following these steps, you can successfully create an HTTPS server in Node.js using the provided SSL key and certificate.
