We have been exploring the idea of transitioning some of our angular projects to typescript, but we are encountering difficulties with internal modules/namespaces.
For reference, we have shared a working example on github: https://github.com/hikirsch/TypeScriptSystemJSAngularSampleApp
Here are the steps to follow:
npm install jspm -g
npm install
cd src/
jspm install
jspm install --dev
cd ..
gulp bundle
cd src/
python -m SimpleHTTPServer
This is the essence of the application: 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;
}
}
Although everything works fine in the current setup mentioned above, we would prefer to encapsulate everything within a namespace like so:
module myApp.controllers {
export class ExampleController {
...
}
}
//do we need to export something here?
and then use it in this manner:
After compiling correctly with the gulp bundle task, an error occurs in the browser /// ///
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);
browser error:
