Using window object in Angular 2

gistfile1.txt

// interface for Window
interface Window {
  // add some stuff here
}

let someMockWindowObject = {
  // add some mock functionality here
};

// for browser providers
provide(Window, { useValue: window });

// for node and testing
provide(Window, { useValue: someMockWindowObject })

// inject it
class Foo {
  constructor(private window: Window) {}
}

Does this hold true for the latest angular 2 beta as well?

Anyway you could provide a plunker showing how to use it in a component?

Please provide the actual test case. Because i tried using this but was unable to create the mock object using Window interface. Also it is not allowing to create a Window interface by own because it already finds it in the typings.

I have a line of code in the component which states
window.location.href="any url";
As it gives the full page load test case fails.

There are many properties in the actual Window interface so it is not possible to create the mock for it.

here is an angular4 example, thanks for the code @jeffwhelpley

app.module.ts

providers:[
        {provide: Window, useValue: window }
    ],

x.component.ts

      constructor(private window: Window) {
        this.setVal = window.innerHeight ;
    }

For reference and unit testing, here is what worked for me:
In my service (can be done in a component too):

  setUpBeforeunload(): void {
    window.addEventListener('beforeunload', this.closeConnection);
  }

In my spec (Jasmine testing):

    it('should set up window eventListener', () => {
      spyOn(window, 'addEventListener');
      service.setUpBeforeunload();
      expect(window.addEventListener).toHaveBeenCalledWith('beforeunload', service.closeConnection);
    });

And another test:

    it('should call closeConnection()', () => {
      spyOn(service, 'closeConnection');
      service.setUpBeforeunload();
      window.dispatchEvent(new Event('beforeunload'));
      expect(service.closeConnection).toHaveBeenCalled();
    });
