re: Good article, Florian. If you add: effect to manage side-effects unsubscribe when this service is destroyed replace BehaviorSubject with Replay...
 

Thanks, that's interesting! ReplaySubject... And I thought every Store uses BehaviorSubject ;)
Still for an DIY StateService I think BehaviorSubject is the most straightforward option.

Regarding unsubscribe:
Maybe I can clarify in the post that the services which extend the StateService are supposed to have the lifespan of the application. If such a service would have the lifespan of a component then it should have an option to unsubscribe.

effect is cool!

 

The problem with DIY is that many of the cases are overlooked (and could be error-prone) 😉
What's better than a well-tested tiny lib that handles these for you? 😃

Btw, I typically try to caution about such services that live for the lifespan of the app (unless it's the Globally managed store) - even though I list it as one of the use cases (ngrx.io/guide/component-store/usag... - still working on the docs).
It's very easy to loose track of things.

Is @ngrx/component-store supposed to be used also in long living (app lifespan) singleton services? I thought that state with the lifespan of the app would be more a use case for @ngrx/store.

I will ask you on discord :)
