Making the Purchase

You call the makePurchase() function, shown in Listing 28.28, when a user clicks the Make Purchase button in the billing view. This method sends an $http POST method to the /orders/add route on the server. The POST request contains orderBilling, orderShipping, and orderItems parameters. If the request is successful, the $scope.customer.cart is initialized to [] to match the empty array value that will be set in the customer document in MongoDB.

Also, if the request is successful, a new order document will have been created in the MongoDB database. Therefore, you make another $http request, this time to /orders/get, to get the full list of orders, including the new one. Then the view switches to orders.html.
