https using express code example

Example 1: https with express

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

const app = require('express')();
app.get('*', (req, res) => res.send('<h1>Hello, World</h1>'));

const server = https.createServer({
  key: fs.readFileSync(`${__dirname}/localhost-key.pem`, 'utf8'),
  cert: fs.readFileSync(`${__dirname}/localhost.pem`, 'utf8')
}, app);

await server.listen(443);

Example 2: express http to https

var express = require('express');var app = express(); var redirectToHTTPS = require('express-http-to-https').redirectToHTTPS // Don't redirect if the hostname is `localhost:port` or the route is `/insecure`app.use(redirectToHTTPS([/localhost:(\d{4})/], [/\/insecure/], 301)); app.get('/', function (req, res) {  res.send('Hello World!');}); app.get('/insecure', function (req, res) {  res.send('Dangerous!');}); app.listen(3000, function () {  console.log('Example app listening on port 3000!');}); app.listen(8080, function () {  console.log('Example app listening on port 8080 insecurely!');});
