Nodejs HTTP and HTTPS over same port

Question

I\'ve been googling and looking here at stackoverflow, but I can\'t find an answer I like ;-)

I have a NodeJS server that runs over HTTPS and port 3001. Now I\'d lik

If serving HTTP and HTTPS over a single port is an absolute requirement you can proxy the request to the relevant HTTP implementation directly, rather than piping the socket to another port.

httpx.js

'use strict';
let net = require('net');
let http = require('http');
let https = require('https');

exports.createServer = (opts, handler) => {

    let server = net.createServer(socket => {
        socket.once('data', buffer => {
            // Pause the socket
            socket.pause();

            // Determine if this is an HTTP(s) request
            let byte = buffer[0];

            let protocol;
            if (byte === 22) {
                protocol = 'https';
            } else if (32 < byte && byte < 127) {
                protocol = 'http';
            }

            let proxy = server[protocol];
            if (proxy) {
                // Push the buffer back onto the front of the data stream
                socket.unshift(buffer);

                // Emit the socket to the HTTP(s) server
                proxy.emit('connection', socket);
            }
            
            // As of NodeJS 10.x the socket must be 
            // resumed asynchronously or the socket
            // connection hangs, potentially crashing
            // the process. Prior to NodeJS 10.x
            // the socket may be resumed synchronously.
            process.nextTick(() => socket.resume()); 
        });
    });

    server.http = http.createServer(handler);
    server.https = https.createServer(opts, handler);
    return server;
};

example.js

'use strict';
let express = require('express');
let fs = require('fs');
let io =  require('socket.io');

let httpx = require('./httpx');

let opts = {
    key: fs.readFileSync('./server.key'),
    cert: fs.readFileSync('./server.cert')
};

let app = express();
app.use(express.static('public'));

let server = httpx.createServer(opts, app);
let ws = io(server.http);
let wss = io(server.https);
server.listen(8080, () => console.log('Server started'));
