IONIC Not receiving Socket data


#1

I am using ionic in client and MEANJS for my server. i am not receiving socket data from server. i was told my code lacked necessary things to append updated data on server in realtime, i tried but did not work.
My Service

.service('Socket', ['Authentication', '$state', '$timeout', '$rootScope',
function (Authentication, $state, $timeout, $rootScope) {
// Connect to Socket.io server
this.connect = function () {
  // Connect only when authenticated
  if (Authentication.user) {
    this.socket = io('https://cryptic-savannah-60962.herokuapp.com');
  }
};
this.connect();

// Wrap the Socket.io 'on' method
this.on = function (eventName, callback) {
  if (this.socket) {
    this.socket.on(eventName, function (data) {
      $timeout(function () {
        $rootScope.$apply(function () {
        callback.apply(data);
      });
      });
    });
  }
};

// Wrap the Socket.io 'emit' method
this.emit = function (eventName, data) {
  if (this.socket) {
    this.socket.emit(eventName, data);
  }
};

// Wrap the Socket.io 'removeListener' method
this.removeListener = function (eventName) {
  if (this.socket) {
    this.socket.removeListener(eventName);
  }
};
}])

My Controller

if (!Socket.socket && Authentication.user) {
  Socket.connect();
}

Socket.on('orderCreateError', function (response) {
  $scope.error = response.message;
});

Socket.on('orderCreateSuccess', function (response) {
  if ($scope.orders) {
    $scope.orders.unshift(response.data);
  }
});

Socket.on('orderUpdateSuccess', function (response) {
if ($scope.orders) {
    $scope.$apply(function() {
        $scope.orders.push(response.data);
        $scope.orders = Orders.query();
    });
}
});

  $scope.saveUsingSocketEvents = function(isValid) {
  $scope.error = null;

  if (!isValid) {
    $scope.$broadcast('show-errors-check-validity', 'orderForm');
    return false;
  }


    var order = new Orders({
        name: this.name,
        phone: this.phone,
    });

  // we can send the user back to the orders list already
  // TODO: move create/update logic to service
  if ($scope.order._id) {
    order.$update(successCallback, errorCallback);
  } else {
    order.$save(successCallback, errorCallback);
  }

  function successCallback(res) {
    $state.go('orders.view', {
      orderId: res._id
    });
  }

  function errorCallback(res) {
    $scope.error = res.data.message;
  }

  // wait to send create request so we can create a smooth transition
  $timeout(function () {
    // TODO: move create/update logic to service
    if ($scope.order._id) {
      Socket.emit('orderUpdate', $scope.order);
    } else {
      Socket.emit('orderCreate', $scope.order);
    }        
  }, 2000);
}

Example of including socket.io in Ionic 2?
