Part 2 of our series on State Management in Angular focuses on the use of RxJS in order to leverage Observables, Subjects, and BehaviorSubjects in Angular applications.

First, Aaron Frost and Jennifer Wadella talk through how RxJS is used by Angular developers to persist state in singleton services using Subjects. This is a common approach to implementing a single source of truth with the observable pattern in Angular. Another benefit of the approach is a path to implementing a state management library such as NgRx in an Angular application when necessary.

Then, Ben Lesh joins Brian Love and the other panelists to share his story of how he personally got started on the RxJS project. One of the major drawbacks of using promises is a lack of a cancellation feature. While at Netflix, the team resolved this by using the Observable primitive. Ben also shares the story of how he was tasked with refactoring RxJS to follow the then-to-be approved TC39 proposal for the Observable primitive. We then learn from Ben about the current work that is being done by the RxJS core team and the future of RxJS.

Finally, Ben drops some knowledge on a simple philosophy: if the code you write works, can be maintained, and is testable, then it's good code. The end.
