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

Using classes and inherit from ng.IDirective is the way to go with TypeScript:

class MyDirective implements ng.IDirective {
    restrict = 'A';
    require = 'ngModel';
    templateUrl = 'myDirective.html';
    replace = true;

    constructor(private $location: ng.ILocationService, private toaster: ToasterService) {
    }

    link = (scope: ng.IScope, element: ng.IAugmentedJQuery, attrs: ng.IAttributes, ctrl: any) => {
        console.log(this.$location);
        console.log(this.toaster);
    }

    static factory(): ng.IDirectiveFactory {
        const directive = ($location: ng.ILocationService, toaster: ToasterService) => new MyDirective($location, toaster);
        directive.$inject = ['$location', 'toaster'];
        return directive;
    }
}

app.directive('mydirective', MyDirective.factory());
