A service can be dynamically injected (by name) into a controller using the $injector. Being able to inject services via controller arguments is just a convenience that Angular provides. Under the hood, the $injector is used by Angular to retrieve object instances. But we can use the $injector ourselves also. function MyCtrl($scope, $injector) { $scope.doSomething = function(someService) { var service = $injector.get(someService) // someService contains the name of a service service.value += 10 } https://stackoverflow.com/questions/14415845/angularjs-dynamically-inject-scope-or-controller/14418384#14418384 https://docs.angularjs.org/api/auto/service/$injector
