Express - Nodejs - HTTPS Server

Question

i'm using https server with express in my app, the problem is that express never listens on that port, it works with http but not with https

app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));

app.use(function (error, req, res, next) {
    if (error instanceof SyntaxError) {
        res.status(400).json({
            status: 'failed',
            message: "Enter a valid JSON object."
        });
    } else {
        res.header('Cache-Control', 'private, no-cache, no-store, must-revalidate');
        res.header('Expires', '-1');
        res.header('Pragma', 'no-cache');
        next();
    }
});
app.use(cors());
app.use(morgan('dev'));
require('./config/routes.js')(app);
server = https.createServer({
        key: fs.readFileSync(process.env.SSL_LOCATION+"ssl.key"),
        cert: fs.readFileSync(process.env.SSL_LOCATION+"ssl.cert")
    },app).listen(parseInt(process.env.SOCKET_PORT, 10) || 4000, '0.0.0.0',function(){
        console.log('Express server listening to port '+parseInt(process.env.SOCKET_PORT, 10) || 4000);
    });
    io = require('socket.io').listen(server);

but if i add

port=5455
app.listen(port);

express starts listening but on different port any suggestions?

Answer 1

Try to replace your port with a constant number and test it. Also, try to run my code below (it is based on yours and works for me). Write if it doesn't solve your problem.

const https = require('https');
const express = require("express");
const fs = require('fs');
const bodyParser = require("body-parser");
const morgan = require('morgan');

app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));
app.use(morgan('dev'));

// for test
app.get('/', (req, res) => {
    res.send("Work");
})

const server = https.createServer({
        key: fs.readFileSync("./ssl.key"),
        cert: fs.readFileSync("./ssl.crt")
},app)
server.listen(8000)
io = require('socket.io').listen(server);
console.log('Start');
console.log(server.address().port);
