Angular 17 introduces Signals, a new reactive primitive for managing local component state, offering a cleaner and more intuitive approach compared to using NgRx and RxJS.
Signals provide a simpler API with lower complexity, minimal boilerplate, and automatic change detection, making them ideal for managing local/component state and UI-related functionalities.
Examples provided demonstrate how Signals can be used in scenarios like managing a counter, toggling visibility, and deriving state, showcasing their advantage in readability and reactivity.
To decide between Signals, RxJS, and NgRx, consider using Signals for local state, UI flags, and deriving state, while reserving RxJS/NgRx for asynchronous data, global state, side effects, and advanced features.
