rxjs - stop observable with a subject subscription

I think the issue was by ths following , Fortunately, there is a dedicated and elegant way to solve this in RxJS.
Your requirement is to have
code :
const timer$ = 
    new rxjs.Observable(subscriber => {// your unchanged implementation})
    .pipe(
        share()
    );

const subscription = timer$.subscribe(value => console.log("observer %s", value));

Angular2 rxjs/Subject , rxjs/Observable events not working across the parent and child router

Hope that helps Ensure you have GlobalService only provided once at the root component. If you add it to providers of every component where you use it, each component gets it's own instance and if one subscribes its a different instance then where events are emitted and therefore doesn't get notified.
Angular2 DI maintains a single instance per provider

How to create Observable from Subject without exposing the Subject to consumers in RxJs v5


By : James Blake

like below fixes the issue The only way, that I know of, to truly encapsulate this would be to subscribe to the subject inside your function and and have another (either subject or custom obervable) returned that emits those value(s).
But any operator (even the creation-operators like Observable.combineLatest(subject)) has some way to access the source.

RxJS Keep Subject/Observable Subscription Active After Error

Does that help Simply said, you can't. At least not with Subjects.
Subjects have internal state and when they emit or receive error notification they mark themself as stopped and will never ever emit anything.

Return Observable of arrays from rxjs/Subject (Observable.from vs. Observable.of)

will help you It would be easier if you would provide a plunker. So far I think that you are confusing Observable.from and Observable.of:
Observable.from
code :
return Observable.from(myModels)
return Observable.of(myModels)
var myModels = ["a", "b", "c", "d"]
Observable.from(myModels).subscribe(value => console.log("value is: " + value));
Observable.of(myModels).subscribe(value => console.log("value is: " + value));
value is: a
value is: b
value is: c
value is: d
value is: [a, b, c, d]

Rxjs: Is the observable born out of asObservable method of Subject the same as the source Subject?

I wish this help you
The asObservable method returns an Observable that has the subject as its source:
code :
export class Subject<T> extends Observable<T> implements ISubscription {
  ...
  asObservable(): Observable<T> {
    const observable = new Observable<T>();
    (<any>observable).source = this;
    return observable;
  }
}
