Question

我们正在考虑将一些角度项目移到打字稿上，并在内部模块/命名空间方面遇到一些麻烦。

我们在github上发布了这个工作示例：https://github.com/hikirsch/TypeScriptSystemJSAngularSampleApp

步骤：

npm install jspm -g
npm install
cd src/
jspm install
jspm install --dev
cd ..
gulp bundle
cd src/
python -m SimpleHTTPServer

这是应用程序的要点： index.ts

/// <reference path="../typings/tsd.d.ts" />
/// <reference path="../typings/typescriptApp.d.ts" />

import * as angular from 'angular';

import {ExampleCtrl} from './controllers/ExampleCtrl';
import {ExampleTwoCtrl} from './controllers/ExampleTwoCtrl';

export var app = angular.module("myApp", []);

app.controller("ExampleCtrl", ExampleCtrl);
app.controller("ExampleTwoCtrl", ExampleTwoCtrl);

ExampleCtrl.ts

/// <reference path="../../typings/tsd.d.ts" />
/// <reference path="../../typings/typescriptApp.d.ts" />


export class ExampleCtrl {
    public static $inject:Array<string> = [];

    constructor() {

    }

    public name:string;
    public hello_world:string;

    public say_hello() {
        console.log('greeting');

        this.hello_world = "Hello, " + this.name + "!";
    }
}

ExampleTwoCtrl.ts

/// <reference path="../../typings/tsd.d.ts" />
/// <reference path="../../typings/typescriptApp.d.ts" />

export class ExampleTwoCtrl {
    public static $inject:Array<string> = [];

    constructor() {

    }

    public name:string;
    public text:string;

    public second() {
        this.text = "ExampleTwoCtrl: " +  this.name;
    }
}

如上所述，这一切都很好。但我们宁愿将所有内容都放在这样的名称空间下：

module myApp.controllers {
    export class ExampleController {
        ...
    }
}
//do we need to export something here?

然后像这样使用它：

这将正确编译运行gulp bundle任务，但在浏览器中出错 /// ///

import * as angular from 'angular';

import ExampleCtrl = myApp.controllers.ExampleCtrl;
import ExampleTwoCtrl = myApp.controllers.ExampleTwoCtrl;

export var app = angular.module("myApp", []);

app.controller("ExampleCtrl", ExampleCtrl);
app.controller("ExampleTwoCtrl", ExampleTwoCtrl);

浏览器错误：

根据typescript documentation，在编译为commonjs时不需要使用内部模块。如上所述：

TypeScript中外部模块的一个关键特性是两个不同的外部模块永远不会为同一范围提供名称。因为外部模块的使用者决定分配什么名称它，没有必要主动包装出来的符号命名空间。

我发现使用commonjs加载器（我使用的是browserify）使用typescript的最佳方法是执行以下操作：

class ExampleTwoCtrl {
    public static $inject:Array<string> = [];

    constructor() {

    }

    public name:string;
    public text:string;

    public second() {
        this.text = "ExampleTwoCtrl: " +  this.name;
    }
}

export = ExampleTwoCtrl

并使用它：

import MyController = require('./ExampleTwoCtrl');
var a = new MyController();

话虽这么说，我观看了来自John Papa's talk at AngularU的录音，他们演示了一些使用在typescript中编写的systemjs捆绑的代码，没有任何导入，只有内部ts模块。我在twitter上问我哪里可以找到示例代码，但还没有得到回复。
