npm init 
touch server.js

4. Install express js

npm install express

5. Copy these files created in step 3 [domainname]-key.pem, [domainname].pem and paste it in this folder.
6. Include this below code in server.js

'use strict';

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

const options = {
    key: fs.readFileSync('[domainname]-key.pem'),
    cert: fs.readFileSync('[domainname].pem'),
  };

const app = express();
app.get('/', (req, res, next) => {
    res.send("Localhost hosted in https !")
});
https.createServer(options, app).listen(3000);

7. Test the application by opening the browser and hitting the URL
