Pizza++ with Firebase (AngularFire)

1. Add the Firebase and AngularFire libraries to index.html.

   <script src="https://cdn.firebase.com/js/client/2.2.4/firebase.js"></script>
   <script src="https://cdn.firebase.com/libs/angularfire/1.2.0/angularfire.min.js"></script>
   

2. Add 'firebase' as an app level module dependency.

3. Create a new Firebase app instance (on http://firebase.com).

4. Store the Firebase instance address into a constant (in app.js).

   angular.module(...).constant('FBURL', 'vivid-inferno-8565.firebaseio.com')
   

5. Structure the JSON data in the just created Firebase app. Delete the data folder from the project.

6. Edit the Pizza service to get all pizzas from the Firebase app instance.

   angular.module(...).factory('Pizza', function pizzaService(FBURL, $firebaseArray) {
       var ref = new Firebase(FBURL + '/pizzas');
       return {
           getPizzas: function() {
               return $firebaseArray(ref);
           }
       }
   });
   

7. Call the getPizzas() function from the pizza-list.js controller instead of the "old" service.

8. Update the pizza-list.html view to generate links with the built-in $id instead of the self-declared id.

9. Update the Pizza service to get single pizza information from the Firebase app instance.

   angular.module(...).factory('Pizza', function pizzaService(FBURL, $firebaseArray, $firebaseObject) {
      var ref = new Firebase(FBURL + '/pizzas');
      return {
          ...
          getPizza: function(id) {
              var pizzaRef = new Firebase(FBURL + '/pizzas/' + id);
              return $firebaseObject(pizzaRef);
          }
      }
   });
   

10. Consequently, call the getPizza() function from the pizza-detail.js controller.
