What is the use of HTTPS modules in Node JS

HTTPS is the HTTP protocol over TLS/SSL. In Node.js this is implemented as a separate module.

Can do all sorts of request over the http/https network . 

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

const options = {
  pfx: fs.readFileSync('test/fixtures/test_cert.pfx'),
  passphrase: 'sample'
};

https.createServer(options, (req, res) => {
  res.writeHead(200);
  res.end('hello world\n');
}).listen(8000);
