///USE THIS



var app = express();
app.io = require('socket.io')();

var routes = require('./routes/index')(app.io);

app.use('/', routes);

//Normal code here

//then at the bottom:

module.exports = function (io) {
    //Socket.IO
    io.on('connection', function (socket) {
        console.log('User has connected to Index');
        //ON Events
        socket.on('admin', function () {
            console.log('Successful Socket Test');
        });

        //End ON Events
    });
    return router;
};

/**
 * Create HTTP server
 */

var server = http.createServer(app);
app.io.attach(server);
/**
 * Listen on provided port, on all network interfaces.
 */

server.listen(port);
server.on('error', onError);
server.on('listening', onListening);


/**
 * Normalize a port into a number, string, or false.
