This walks you through the modern Angular reactive patterns you'll actually use: BehaviorSubject for state management, proper Observable service setup, and the async pipe in templates. It covers the essentials like shareReplay for caching HTTP calls and takeUntil for cleanup, which honestly should be muscle memory if you're doing Angular professionally. The examples are current with Angular 21's control flow syntax, and the code snippets are practical enough to copy and adapt. If you're still manually subscribing everywhere or not using BehaviorSubject for shared state, this will get you on track quickly.
