Subjecting State to Good Behavior

on YouTube ↗20m

" summary

Shows concrete, runnable patterns using RxJS instead of NgRx: a small APOD app and a NEO app that use BehaviorSubject + scan to compose immutable OnPush-ready state, a private subject exposed via asObservable, and a single public set/update API. Demonstrates optimistic updates with rollback (UI updates immediately, API success leaves it, API error reverts and emits an error), and explains where this saves code and when a full store is warranted.
