I am workig on an Ionic4 Angular project using NGRX and Firestore.
There is fairly enough information available about this combination, using @Effects.
One part for which I would love to hear your views on the aspect of changing data and having them synced with Firestore and ngrx Store:
Update the Firestore using Effects and then wait until the Firestore pushes the update to the ngrx Store in the app, or update the ngrx Store and the Firestore to ensure the user immediate sees the changes.
For the latter solution I wonder what the best strategy is for low bandwidth phones (slow responses). I am considering a parallel update where in the end the Firestore will overrule the ngrx Store, taking the Firestore as the single source of truth.
Is there any other option you can think of? With not too much efforts of course
