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

[exilonX]

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...

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

Use like This

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

For future readers, you need to explicitly specify the protocol (as the Node.js process has no window.location object it could deduce the protocol from, which is what is done in the browser here).

// does not work
io.connect("localhost:8080");
// does work
io.connect("http://localhost:8080");

That being said, I think the client should throw an error instead of silently failing.

Thanks for this suggestion, it worked for me

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

this is my conection
app = express()
app.use(cors())

const server = require('http').createServer(app);
const io = require('socket.io')(server,{
cors: {
origin: "*"
}
