Socket.io does not work on Firefox & Chrome

Question

I\'m trying to develop a simple chat application. Here is my chat.js file.

var app = require(\'http\').createServer(handler)
, io = require         


        

Answer 1

Thankyou ebohlman for your time but I solved the problem. In my chat.js I added the following line.

io.configure('development', function(){
  io.set('transports', ['xhr-polling']);
});

Now my chat.js looks like.

var app = require('http').createServer(handler)
, io = require('socket.io').listen(app)
, fs = require('fs');

app.listen(8124);

io.configure('development', function(){
  io.set('transports', ['xhr-polling']);
});

function handler (req, res) {
fs.readFile(__dirname + '/chat.html',
function (err, data) {
if (err) {
res.writeHead(500);
return res.end('Error loading chat.html');
}
res.writeHead(200);
res.end(data);
});
}
io.sockets.on('connection', function (socket) {
    socket.on('addme',function(username) {
        socket.username = username;
        socket.emit('chat', 'SERVER', 'You have connected');
        socket.broadcast.emit('chat', 'SERVER', username + ' is on deck');
    });
    socket.on('sendchat', function(data) {
        io.sockets.emit('chat', socket.username, data);
    });
    socket.on('disconnect', function() {
        io.sockets.emit('chat', 'SERVER', socket.username + ' has left the building');
    });
});

But I still don't know what might have caused the error. If you know please explain!
