Leveraging personalized services prior to initializing the AngularJS application

I am attempting to utilize custom services prior to the application's initialization.

var initInjector = angular.injector(['ng', 'myModule']);

var myCustomService = initInjector.get('myCustomService');

var $http = initInjector.get('$http');

var $q = initInjector.get('$q');

Within myCustomService, I have the following code:

angular.module('myModule').service('myCustomService',myCustomService);

 function myCustomService($location, $q){
   // some logic
 }

The error message I encountered is :

Uncaught Error: [$injector:unpr] Unknown provider: $rootElementProvider <- $rootElement <- $location <- myCustomService <- $location

It appears that the dependencies referenced in myCustomService are not being loaded properly.

Is there a more efficient way to organize the pre-bootstrap code and logic?

Answer №1

Although I am responding late, based on the error message shared in the original question, it appears that $location needs to be accessible prior to the application bootstrap.

In order to obtain the $location before bootstrapping, you would have to provide the $rootElement. One method involves mocking it: by injecting the ngMock module from angular-mocks to access the injector.

var initInjector = angular.injector(['ng', 'myModule', 'ngMock']);
var $location = initInjector.get('$location');

It may also be beneficial to refer to this post on StackOverflow and this discussion on GitHub.
