Projects:

fun-with-rx-services	Introduction to reactive development in angular

RxJS in Angular Services

• We learned how to develop stateful services using BehaviorSubject and expose it as an observable using the .asObservable() method
• We understood that if we subscribe to an observable we must also unsubscribe from it when we are done with it to avoid memory leaks
• We saw that we can bind directly to an observable using the async pipe in the html
• We learned the term Fully Reactive Application as one where we pass observables all the way from the services to the html templates
• We saw how to configure manual change detection for components and understood that it can dramatically improve performance
• We saw how to inject the ChangeDetectorRef and to manually activate detectChanges to force invalidation of the DOM
