Customizing the window object with a global property in Angular 2 using Typescript

As someone who is relatively new to Angular 2, I am attempting to create a global namespace by setting up window.Dashboard. Although my main page and jasmine tests are loading successfully, my compiler watch keeps quitting and giving me the error "Property 'Dashboard' does not exist on type ‘Window'. Here is a link to the code on pastebin for reference: http://pastebin.com/DF9wXexH. Any insights or suggestions on what might be causing this issue would be greatly appreciated! Thanks!!

//main.ts
import { bootstrap } from 'angular2/platform/browser';

import { DashComponent } from './dash.component';


bootstrap(DashComponent);

//dash.component.ts

import { Component } from 'angular2/core';

interface Window {
    Dashboard?: any;
}

@Component({
    selector: 'main',
    template: '<h1>Welcome To The Dashboard</h1>'
})

export class DashComponent {
    constructor() {}
}

Answer №1

You specify the Dashboard as optional in your interface by using the ?. However, I notice that there is no initialization for it. Without proper initialization, the Dashboard won't be available. Consider removing the question mark or providing an initialization for it. It might also be a good idea to rename the interface from IWindow to prevent any confusion with the global window object.
