Missign injectable in directive with Classes

[bastienmoulia]

Following https://github.com/toddmotto/angular-styleguide/blob/master/README.md#constants-or-classes

When i want to use a Class in directives I think the injectable should be added to the module:

export const TodoModule = angular
  .module('todo', [])
  .component('todo', TodoComponent)
  .directive('todoAutofocus', () => new TodoAutoFocus())
  .name;

must be

export const TodoModule = angular
  .module('todo', [])
  .component('todo', TodoComponent)
  .directive('todoAutofocus', ['$timeout', ($timeout) => new TodoAutoFocus($timeout)])
  .name;

to avoid the message error TS2346: Supplied parameters do not match any signature of call target.
