How Angular Signals and RxJS Work Together

Common questions I hear when talking about signals involve RxJS.
"Do signals replace RxJS?" "Is RxJS going away?" "How do signals work with RxJS?"

To answer these questions, let's take an Angular application that uses RxJS and modify it to include signals. We'll look at creating signals from Observables, and binding to those signals. And we examine techniques for reacting to a signal in an Observable pipeline.

This video assumes you have a basic knowledge of signals, the new feature in Angular v16. Signals provide more reactivity and finer control over change detection. If you aren't familiar with signals, consider watching my introductory signals video first. You can find the link below.

NOTE: The Angular team announced that they will be changing (possibly later this week):
fromObservable 👉 toSignal
fromSignal 👉 toObservable
