State Management Techniques and Family Therapy
summary
Concrete claim: ngrx gives a maintainable unidirectional state with a single source of truth and composable selectors. Code-level proof: TypeScript examples for actions reducers selectors effects, reducers as pure functions, selectors memoized and observable, effects handling API calls via RxJS and switchMap. Migration notes include facades used before adopting ngrx, onPush change detection enabled by store.select observables, and practical tooling like store devtools and component store with guidance on when to write tests.
