Node js - Socket.io-client is not connecting to socket.io server

Question

I am trying to connect to a socket.io-client using the following code:

Server:

// Load requirements
var http = require('http'),
    io = require('socket.io');

// Create server & socket
var server = http.createServer(function(req, res){

    // Send HTML headers and message
    res.writeHead(404, {'Content-Type': 'text/html'});
    res.end('<h1>Aw, snap! 404</h1>');
});
server.listen(8080);
io = io.listen(server);

// Add a connect listener
io.sockets.on('connection', function(socket) {

    console.log('Client connected.');

    // Disconnect listener
    socket.on('disconnect', function() {
        console.log('Client disconnected.');
    });
});

Client:

console.log('1');

// Connect to server
var io = require('socket.io-client')
var socket = io.connect('localhost:8080', {reconnect: true});

console.log('2');

// Add a connect listener
socket.on('connect', function(socket) {
    console.log('Connected!');
});

console.log('3');

I don't get the Connected console log or Client Connected console log and I don't know why! The code sample is taken from another question posted: Link and I don't see any solution to the problem...

Answer 1

Use the same version of socket io client and server. It will work perfectly.

Answer 2

Also you need to add protocol with path.

change

var socket = io.connect('localhost:8080', {reconnect: true});

to

var socket = io.connect('http://localhost:8080', {reconnect: true});
