You should read socketio doc: http://socket.io/docs/

On the client side you send the data like this:

socket.emit('inputbox', data)

On the server side inside the "io.on" callback you use:

socket.on('inputbox', function (data) {
    console.log(data)
  })

There is also a very detailed tutorial that should get you started: http://socket.io/get-started/chat/
