Great video. Actually had this problem a couple of weeks ago. Figured out that shareReplay(1) is what holds the subscription even after async pipes unsubscribe (because the component is destroyed). Always thought that putting takeUntil() at the end of the pipeline will get rid of it. But this time it was actually the other way around, I needed to put it before shareReplay(1). Just as I wanted to experiment more and find out why is that, your video came out. Thank you. The internal concepts are always good to know, so do indeed continue with these type videos. Thank you :)

Many thanks for the great video. While the refCount solution is simple to understand, it has drawbacks: sometimes you may want to keep the cache even after the last unsubscription. Can you provide advise on this situation? My guess would be that we should do some kind of takeUntil immediately before shareReplay(1) (as the comment at the very beginning suggested). I think this would work as the conpletion would cause shareReplay's inner subscription to unsubscribe. If you agree, I think this would be a superior general approach to using refCount (as the cache persists even after the last unsubscription).
@greenoxxx2827Ай бұрын
Thank you for creating this video! It's helped me realize how much I could improve my previous code. I'm eager to see more content from you. I recently faced a challenge with applying form controls and validators from a parent form to a custom input element. While I understand that ngModel handles control values, how can I access the validators defined in the parent form within my custom component?
@MrXandriosАй бұрын
using this approach takes the "complexity" of those frameworks away, because it shows, there is no black magic involved. So taking this approach might be the right thing
@deadlyechoАй бұрын
Also, a socket is an example of memory leak since the internal subscription will be left alive even if the component is destroyed, right?
@DecodedFrontendАй бұрын
Yes, if the source of the nested subscription would be a socket connection (instead of polling), it would be the same problem.

@andrelouw2677Ай бұрын
In your example where you have a cache that should keep running (let's say in a service). When the component disconnects, it should still keep a cached version. When the component connects again it will immediately have a value. How and where would you then kill the subscription to that first source. Lets say when the service is destroyed... in my case I have a firebase subscription that I cache in a service. All the components then use that value. How can I make sure that the firebase sub is destroyed?

If the subscriptions cause memory leaks, why Angular can't destroy it by default when onDestroy the component. It's a headache for developers to find the memory leaks
@DecodedFrontendАй бұрын
I think this question better to ask angular core team :) But yeah, I understand that this is quite annoying to always keep in mind the memory leaks.
@AlejandroMorenteCamposАй бұрын
What happens with late subscriptions when the source Observable doesn't have any subscriptions left? It shouldn't make another http request in this case because the inner ReplaySubject should replay the value, right?
@DecodedFrontendАй бұрын
when refcount drops back to 0, the observable should go back to the cold state which means that the http call should be executed when a new subscriber arrives later
@kramatangaАй бұрын
is not bad to use nested subscriptions ?
@DecodedFrontendАй бұрын
Usage of nested subscription is absolutely fine and you can not avoid it actually because very often our stream might depend on the value from other one. Just make sure that you use proper operators for that (e.g switchMap, etc) instead of doing obs$.subscribe(val => obs2$.subscribe(...))
@radvilardian740Ай бұрын
humm, takeUntil before shareReplay won'tbe useful here?
@DecodedFrontendАй бұрын
Thanks for your question. takeUntil + Subject would help, this is true. However, there are a few reasons why I would not do this: - takeUntil pattern requires more boilerplate because it needs additionally a Subject and onDestroy hook where the Subject has to emit destroy event. You can suggest usage of the takeUntilDestroy operator which is only 1 line, but it will be a one-line-solution only if this operator is used in the constructor/injector context. Otherwise, you have to inject destroyRef or injector and provide it as an argument value for takeUntilDestroy. - takeUntil + Subject and takeUntilDestroyed operators have also pitfalls that might cause memory leaks and you have to always care about the position of takeUntil in the operator chain. I covered it in this video - kzfaq.info/get/bejne/m7CjZ6h7urXSfnk.htmlsi=Dqkn1-cmB2BjS_0s 3. takeUntil + Subject solves automatic unsubscription as well as the AsyncPipe, so to me, it is simply confusing to see additional unsubscription logic for the observable managed by async pipe.
@radvilardian740Ай бұрын
@@DecodedFrontend nice, takeUntilDestroyed is a good choice I think, and yeah better use it in the injector context, that's why i like to use declarative approach for the rxjs. Thanks.

Take until also has its own pitfalls :) You can check it out here - kzfaq.info/get/bejne/m7CjZ6h7urXSfnk.html Also, takeUntil should be used along with Subject and ngOnDestroy hook which is already more then 1 line :)
