private $templateCache

I decided to add another answer describing more details how to create and use controller in TypeScript and inject it into angularJS.

This is extension of this Answer

How can I define my controller using TypeScript? Where we also have a working plunker

So having this directive:

export class CustomerSearchDirective implements ng.IDirective
    public restrict: string = "E";
    public replace: boolean = true;
    public template: string = "<div>" +
        "<input ng-model=\"SearchedValue\" />" +
        "<button ng-click=\"Ctrl.Search()\" >Search</button>" +
        "<p> for searched value <b>{{SearchedValue}}</b> " +
        " we found: <i>{{FoundResult}}</i></p>" +
    public controller: string = 'CustomerSearchCtrl';
    public controllerAs: string = 'Ctrl';
    public scope = {};

We can see, that we declared this directive to be available as Element. We also in-lined a template. This template is ready to bind SearchedValue and call Action on our controller Ctrl.Search(). We are saying what is the name of controller: 'CustomerSearchCtrl' and asking runtime to make it available as 'Ctrl' (conrollerAs:)

Finally we inject that object into angular module:

app.directive("customerSearch", [() => new CustomerSearch.CustomerSearchDirective()]);

We can use $scope as ng.IScope, but to have more typed access to it, we can create our own interface:

export interface ICustomerSearchScope  extends ng.IScope
    SearchedValue: string;
    FoundResult: string;
    Ctrl: CustomerSearchCtrl;

This way, we know, that we have string SearchedValue and also other string FoundResult. We also informed the application that Ctrl will be injected into that scope, and will be of type CustomerSearchCtrl. And here comes that controller:

export class CustomerSearchCtrl
    static $inject = ["$scope", "$http"];
    constructor(protected $scope: CustomerSearch.ICustomerSearchScope,
        protected $http: ng.IHttpService)
        // todo
    public Search(): void
            .then((response: ng.IHttpPromiseCallbackArg<any>) =>
                var data =;
                this.$scope.FoundResult = data[this.$scope.SearchedValue]
                    || data["Default"];

plus its registration into module

app.controller('CustomerSearchCtrl',  CustomerSearch.CustomerSearchCtrl);

What is interesting on this controller? it has one public acton Search, which has access to all its membes via this., e.g. this.$http. Because we instructed intellisense in VS that angular.d.ts type/interface

protected $http: ng.IHttpService

will be used, we can later easily access its methods. Similar is the type of returned value in .then()

.then((response: ng.IHttpPromiseCallbackArg<any>) => {...

which does contain data: {} of any type...

Hope it helps a bit, observe that all in action here
