Instantiate an object of the ng.IQService type without using injection

Is it possible to define a local variable in the controller of type ng.IQService ( private _q: ng.IQService;) without requiring injection? My technology stack includes typescript and angular. The reason for this requirement is due to existing legacy code that instantiates some objects of the controller type within the controller.

Answer №1

Avoid passing it through the controller

One way to access it without injecting it into the controller is by using the $injector service. Each Angular app comes with a global $injector that is returned from the bootstrap function: https://docs.angularjs.org/guide/bootstrap

You can store the $injector in a global place (like window) and then retrieve $q by using $injector.get('$q').
