Socket Io With AngularJS and loopback

i am trying to develop a real time app using socket io in loopback and AngularJs . I have added socket io dependency and added below code in server.js

app.io = require('socket.io')(app.start());
app.io.on('connection', function (socket) {

  console.log('a user connected');


  socket.on('disconnect', function () {
    console.log('user disconnected');
  });

});

and i also created a Model 'Order' in loopback . but i am not able to integrate socketIo on client side . on stackoverflow and other sites showing chat demo , but i do not need to implement chat app . i need to show 'submitorder' feature . please give me a idea to create a simple app using Socketio with loopback and AngularJs.

i did many mistake in English , please ignore .
