RxJS Recipes
summary
Builds a small Angular jokes app and demonstrates concrete RxJS solutions: polls every 5s with timer + exhaustMap + shareReplay to cache and restart, shows backpressure handling by only applying updates when a user clicks, emits a one-time "update available" notification by skipping the first value, manages settings with BehaviorSubject + scan for state, toggles polling via switchMap + distinctUntilChanged, and composes retryWhen with conditional online checks (retry every 1s up to 5 or wait until online). All examples run live in the demo.
