I’m trying to chat in Ode js, but when I start the server.js and enter the site, an error appears:
GET http://localhost:3000/socket.io/?EIO=3&transport=polling&t=NfTIQ3t 400 (Bad Request)
This mistake keeps repeating itself, every 3 seconds it makes the same mistake again. Can anyone help me? I don’t know what’s going on.
Here are the codes of index.html and server.js:
//server.js
const express = require('express');
const path = require('path');
const app = express();
const server = require('http').createServer(app);
const io = require('socket.io')(server);
app.use(express.static(path.join(__dirname, 'public')));
app.set('views', path.join(__dirname, 'public'));
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
app.use('/', (req, res) => {
res.render('index.html')
});
io.on('connection', socket => {
console.log(`Socket conectado: ${socket.id}`)
})
server.listen(3000)
console.log('App iniciado')<!DOCTYPE html>
