Node js with express and -can’t fint

So basically what i am trying to do is build a chat app with a login system but for some reason i cant put it together and i am getting an error when i join to the room the chat.hbs can’t find the file and also the main.js is getting a reference error with the const socket = io(); (the chat app works fine without the login system)

Failed to load resource: the server responded with a status of 404 (Not Found)
Uncaught ReferenceError: io is not definedat main.js:11

This is the app.js file

const express = require("express");
const path = require('path');

const http = require('http');
const socketio = require('');

const app = express();

const server = http.createServer(app);
const io = socketio(server);

const botName = "Bot";
app.use(express.static(path.join(__dirname, 'public')));

app.use(express.urlencoded({ extended: false }));
// Parse JSON bodies (as sent by API clients)

app.set('view engine', 'hbs');


//eldönti az útvonalat
app.use('/', require('./routes/pages'));
app.use('/auth', require('./routes/auth'));

app.listen(5001, () => {
  console.log("Server started on Port 5001");

This is the main.js

const chatForm = document.getElementById('chat-form');
const chatMessages = document.querySelector('.chat-messages');
const roomName = document.getElementById('room-name');
const userList = document.getElementById('users');

// Felhasználó név és szoba név URL-ből
const { username, room } = Qs.parse(, {
  ignoreQueryPrefix: true,

const socket = io();

// Csatlakozik chat szobába
socket.emit('joinRoom', { username, room });

// Lekérdezi a szobát felhasználókat
socket.on('roomUsers', ({ room, users }) => {

And the chat.hbs

<script src="/"></script>
<script src="/main.js"></script>
