Komponente

Für einen einfacheren Übergang zu Angular 2 wird empfohlen, Component zu verwenden, das seit Angular 1.5.8 verfügbar ist

myModule.ts

import { MyModuleComponent } from "./components/myModuleComponent";
import { MyModuleService } from "./services/MyModuleService";

angular
    .module("myModule", [])
    .component("myModuleComponent", new MyModuleComponent())
    .service("myModuleService", MyModuleService);

components / myModuleComponent.ts

import IComponentOptions = angular.IComponentOptions;
import IControllerConstructor = angular.IControllerConstructor;
import Injectable = angular.Injectable;
import { MyModuleController } from "../controller/MyModuleController";

export class MyModuleComponent implements IComponentOptions {
    public templateUrl: string = "./app/myModule/templates/myComponentTemplate.html";
    public controller: Injectable<IControllerConstructor> = MyModuleController;
    public bindings: {[boundProperty: string]: string} = {};
}

templates / myModuleComponent.html

<div class="my-module-component">
    {{$ctrl.someContent}}
</div>

Controller / MyModuleController.ts

import IController = angular.IController;
import { MyModuleService } from "../services/MyModuleService";

export class MyModuleController implements IController {
    public static readonly $inject: string[] = ["$element", "myModuleService"];
    public someContent: string = "Hello World";

    constructor($element: JQuery, private myModuleService: MyModuleService) {
        console.log("element", $element);
    }

    public doSomething(): void {
        // implementation..
    }
}

services / MyModuleService.ts

export class MyModuleService {
    public static readonly $inject: string[] = [];

    constructor() {
    }

    public doSomething(): void {
        // do something
    }
}
