HTTPS with Express.js

selfsign.sh

openssl req -nodes -new -x509 -keyout server.key -out server.cert

ssl-app.js

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

const app = require('express')();
const { PORT = 3001, HOST = 'localhost' } = process.env;

app.get('/', (req, res) => {
  res.send('Hello, world!');
})

// - We'd normally do:
// app.listen(PORT, () => console.log(`API listening on http://${HOST}:${PORT}`));

// - But instead:
https.createServer({
  key: fs.readFileSync('server.key'),
  cert: fs.readFileSync('server.cert'),
}, app)
  .listen(PORT, () => console.log(`API listening on https://${HOST}:${PORT}`));
