Advanced State Management using ngrx v5
summary
Shows an actual counter app built with NgRx Store, Effects and the Redux DevTools and demonstrates counter demo with increment decrement reset plus CLI schematics that scaffold boilerplate. Implements a meta-reducer keyed by id to reuse one reducer across multiple counters and proves it works. Identifies a real performance bug: NgRx selectors use one-slot memoization causes cache thrash and fixes it by using createSelectorFactory with multi-slot memoizer, measured by cache hits in the demo.
