Define AngularJS directive using TypeScript and $inject mechanism

Question

Recently I started refactoring one of the Angular projects I am working on with TypeScript. Using TypeScript classes to define controllers is very convenient and works well

Answer 1

In this case I am forced to define angular dependencies in the directive definition, which can be very error-prone if the definition and typescript class are in different files

Solution:

 export function myDirective(toaster): ng.IDirective {
    return {
      restrict: 'A',
      require: ['ngModel'],
      templateUrl: 'myDirective.html',
      replace: true,
      link: (scope: ng.IScope, element: ng.IAugmentedJQuery, attrs: ng.IAttributes, ctrls) => 
        //use of $location service
        ...
      }
    };
  }
  myDirective.$inject = ['toaster']; // THIS LINE
