Creating a HTTPS server with Express

const fs = require('fs');
const KEY = fs.readFileSync('./key.pem');
const CERT = fs.readFileSync('./cert.pem');
const PORT = 8080;
const https = require('https');
const express = require('express');
const app = express();

const server = https.createServer(
  {
    key: KEY, 
    cert: CERT 
  },
app);

app.get('/', (req, res) => { 
  res.send('this is an secure server')
});

server.listen(PORT, () => { 
  console.log(`listening on ${PORT}`) 
});

Step 1 : use fs to read the certificate & key with fs {.fragment .current-only data-code-focus=1-3 }

Step 2 : use port 8080, then use the https module instead of the http module, then use express {.fragment .current-only data-code-focus=4-7 }

Step 3 : Create your HTTPS server and provide it with an object {.fragment .current-only data-code-focus=8-15 }

Step 4 : Create your GET request and listen to your server {.fragment .current-only data-code-focus=13-15 }
