使用获得ES6支持的typescript,使用Angular JS

标签: javascript angularjs typescript

我正在寻找一个给我以下内容的转录器: -

  • 对类使用ES6语法,“let”作用域,胖箭头语法
  • 对导入的一些支持(理想情况下是ES6提议的语法)
  • 支持IE8(即编译为ES3)
  • 与AngularJS的兼容性
  • 与gulp的兼容性
  • 将我的所有代码编译成一个没有requirejs / AMD的文件。

现在,大部分内容都由TypeScript涵盖,但typescript带有自己的类型语法,我不喜欢使用它,因为它似乎要求我下载/设置接口/定义文件。

我玩过它并且我没有太大的成功。你可以看到下面的代码。有人可以请一个替代方案(不,我不想使用Dart),或者告诉我我做错了什么。

app.ts(我的“主要”文件)

/// <reference path="MyController.ts"/>
/// <reference path="MyService.ts"/>
// <reference path="../bower_components/angular/angular.min.js"/>

angular.module("test")
      .controller("MyController", MyController.injections)
      .factory("MyService", MyService.injections);

MyController.ts

/// <reference path="MyService.ts"/>
module MyController {
    class MyController {
        constructor(MyService) {
            this.MyService = MyService;
        }

        callSomething() {
            this.MyService.doSomething();
        }
    }
    export var injections = [ "MyService", MyController ];
}

MyService.ts

module MyService {
    export class MyService {
        constructor($http) {

        }

        doSomething() {
            console.log("Yo");
        }
    }
    export var injections = [ "$http", MyService ];
}

以下是typescript编译器输出的问题: -

我认为这个参考:

// <reference path="../bower_components/angular/angular.min.js"/>

实际上应该是Angular的.d.ts类型定义文件。


在这堂课中:

class MyController {
    constructor(MyService) {
        this.MyService = MyService;
    }

您尝试使用this.MyService,但您从未宣布过它。

class MyController {
    MyService: MyService.MyService;

    constructor(MyService) {
        this.MyService = MyService;
    }

- 或者 - 您可以自动将构造函数参数转换为类变量,如下所示:

class MyController {

    constructor(private MyService: MyService.MyService) {
    }
