Discuss: Reducer / Action Reuse

[Renader]

In my opinion ngrx/store performs poor in regards to reusability. Recently I opened an issue in ngrx/store and got the advice to add a scope string field to my action in order to re-use my reducer. That works but has its drawbacks.

I guess a lot of issues can be resolved (especially effect reuse through extending .ofType() and so on with it) trough adding a scope?: string; field to the {Action} from '@ngrx/store';

Also i think ngrx/store should promote one way of doing it. E.g. should an action have a scope that you pass in when you call the action or should there be a single action for each re-used slice of your state?

Also how should effects be re-used? Afaik the @Effect annotation doesn't work in abstract classes yet.
