Question

Is it possible to utilize AngularJS's $q functionality outside of an Angular component?

I am currently working on a browser application, where I have a specific file responsible for creating and initializing an object. This file is written in plain Javascript rather than being part of the Angular ecosystem like the rest of the app, which is based on AngularJS.

My goal is to incorporate promises into this file, and while Angular does have its own implementation of Q through angular's $q, I would prefer utilizing that instead of adding yet another library.

In addition, I am also making use of RequireJS within my project.

Hence, my question is: Is it possible to leverage $q within a non-Angular file?

Answer №1

To achieve this functionality, you can utilize the angular.injector() method. This method will provide you with an $injector function that allows for injecting dependencies such as $http and $q using its invoke() method.

Check out a DEMO here

Here is an example snippet:

angular.injector(['ng']).invoke(['$q', function($q) {

  $q.when('hello world').then(function(message) {
    window.alert(message);
  });

}]);

It's worth noting that the array supplied to angular.injector() consists of modules. The inclusion of the ng module is important as it contains the core AngularJS dependencies.
