NotificationsService only available on children, not throug router-outlet about angular2-notifications

[dinigo]

Solved it. Noob mistake:

import {NotificationsService} from "angular2-notifications";

/**
  * Every component but the App root one
  */
@Component({
    ...
    providers: [],    // does not contain NotificationsService
    ...
export class AnyOtherComponent(){
    constructor(private ns:NotificationsService){}
    someFunction(){
        this.ns.info('title','content');
    }
}```

I suppose I was overriding the instance for the components

...even if declaring a service globally is discouraged by the official documentation)

Are you sure that declaring services globally in discouraged? I think many services are intended to be used as singletons in that case it makes most sense to include them in the app.component especially if you have to use them on more places across your app.

I went through the official examples and they register providers in the app.component even if they could be registered on a lower component.

Also if you look at the ngrx-example-app for example. All services are registered at root.
