Dependency Injection and Services }; }); retrieveCars(); }); Creating an HTTP facade Now, we have the opportunity to evolve our design by introducing a service that will act as a facade and interact directly with the backend. The mapping of each URL pattern should not be under the controller's responsibility; otherwise, it could generate a huge amount of duplicated code and a high cost of maintenance. In order to increase the cohesion of our controller, we moved the code responsible to make the calls to the backend of the parkingHttpFacade service, as follows: services.js parking.factory("parkingHttpFacade", function ($http) { var _getCars = function () { return $http.get("/cars"); }; var _getCar = function (id) { return $http.get("/cars/" + id); }; var _saveCar = function (car) { return $http.post("/cars", car); }; var _updateCar = function (car) { return $http.put("/cars" + car.id, car); }; var _deleteCar = function (id) { return $http.delete("/cars/" + id); }; return { getCars: _getCars, getCar: _getCar, saveCar: _saveCar, [ 82 ] www.it-ebooks.info
