What is Socket.IO?

Socket.IO aims to make realtime apps possible in every browser and mobile device, blurring the differences between the different transport mechanisms. It's care-free realtime 100% in JavaScript.

var io = require('socket.io').listen(80); io.sockets.on('connection', function (socket) {
         socket.emit('news', {
        hello: 'world' });   socket.on('my other event', function (data) {
           console.log(data);   }); });
