Question

So I moved app.listen to the top, but now it gives me an error that port is in use. I believe this is because I set up my websocket on this port, but how do I do it then?

var server = require('websocket').server, http = require('http');
var express = require('express');
var app = express();
app.listen(8080);

var socket = new server({
    httpServer: http.createServer().listen(8080)
});


socket.on('request', function(request) {
    var connection = request.accept(null, request.origin);

    app.get('/', function(request, response) {
        var id = request.query.steamid;
        console.log("STEAMID:",id);
        response.send("I have received the ID: " + id);
    });

    connection.on('message', function(message) {
        connection.sendUTF(message);
    });

    connection.on('close', function(connection) {
        console.log('connection closed');
    });
}); 

Answer 1

I believe you need to listen on connection and not on request

socket.on('connection', function(sock) {       
    sock.on('message', function(message) {
        sock.send(message);
    });

    sock.on('close', function() {
        console.log('connection closed');
    });
});

put your app.listen(3000); outside of request event. so,your express server get chance to initialize port to listen.

Currently it is in callback of request event and it will get called once client-server connection of web-socket is established.

As far as URL concern

ws://localhost:8080/?steamid=123456789

you have configured websocket to listen on port 8080.But your express is configured to listen port 3000.So it is not possible to catch request on express Server configured on different port which is requested through web-socket configured on another different port.

url should be like this.

http://localhost:3000/?steamid=123456789

because your express server using http protocol and not websocket
