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 socket.io.js 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('socket.io');
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.use(express.json());
app.use(cookieParser());
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(location.search, {
ignoreQueryPrefix: true,
});
const socket = io();
// Csatlakozik chat szobába
socket.emit('joinRoom', { username, room });
// Lekérdezi a szobát felhasználókat
socket.on('roomUsers', ({ room, users }) => {
outputRoomName(room);
outputUsers(users);
});
And the chat.hbs
<script src="/socket.io/socket.io.js"></script>
<script src="/main.js"></script>
Well the problem was that I used:
app.listen(5001, () => {
console.log("Server started on Port 5001");
})
instead of:
server.listen(5001, () => {
console.log("Server started on Port 5001");
})
Szia, you will need to wait for the DOM to load.
window.addEventListener('load', function () {
// Your code goes here
const socket = io();
socket.on("connect", () => {
// you can only emit once the connection is established.
socket.emit('joinRoom', { username, room });
});
})
