Angular Signal vs BehaviorSubject

Signal vs RxJS Behavior Subject. Fight! Just kidding. 😆

In reality, there are use cases for both. In this video, we take a look at how to replace a synchronous BehaviorSubject stream with a signal.

Starting in Angular v16, Angular developers can leverage the power of signals to create more reactive applications. Signals provide a new way for our code to inform our templates that data has changed, offering more granular control over how and when updates are propagated with change detection. If you aren't familiar with signals, consider watching my introductory signals video first. You can find the link below.
