Description

Add entity action as they are in Akita: https://datorama.github.io/akita/docs/entities/query-entity/#entity-actions

Proposed solution

import { selectEntityAction, EntityActions  } from '@ngneat/elf-entities';

// Listen for a specific action
store.query(selectEntityAction(EntityActions.Set)).subscribe(newIds => {})
store.query(selectEntityAction(EntityActions.Add)).subscribe(addedIds => {});
store.query(selectEntityAction(EntityActions.Update)).subscribe(updatedIds => {});
store.query(selectEntityAction(EntityActions.Remove)).subscribe(removedIds => {});

// listen for a subset of actions
store.query(selectEntityAction([EntityActions.Add, EntityActions.Remove])).subscribe(action => {});

// listen for all actions
store.query(selectEntityAction()).subscribe(action => {});

@NetanelBasal, what do you suggest to implements this new feature ?

In Akita an observable is used to propagate entities event.

However in Elf every mutation functions is a pure function.

[NetanelBasal]

Yes. We can exclude the core entity mutations for this benefit and emit the action in each.

import { ofType } from '@ngneat/elf';
import { EntityActions } from '@ngneat/elf-entites';

store.actions$.pipe(ofType(EntityActions.Add)).subscribe()
