Angular applications often struggle with managing complex UI state and derived data between components, leading to scattered logic and hard-to-maintain code. This Skill provides proven patterns for using Angular Signals to centralize state, derive computed values, and drive side effects without RxJS.
Install Angular Signals in your project and create a simple store using signal(), computed(), and update() to drive a component.

You can manage Angular state without RxJS by using writable signals for primary UI state, computed signals for derived data, and effects to coordinate side effects across components and services.
A signal holds writable primary state, while a computed signal derives read-only state reactively from other signals, automatically updating whenever its dependencies change.
Testing Angular Signals involves verifying signal creation, computed derived state, and effect execution by asserting value updates and side effect coordination within your component and service test suites.
Yes, Angular Signals support scalable state management in large apps by centralizing state in services, deriving computed values, and coordinating side effects without RxJS boilerplate.
Use computed for deriving state values reactively, and use effect when you need to execute side effects like logging or data synchronization in response to signal value changes.
Angular Signals excel at synchronous state derivation and side effects, but complex asynchronous event streams and multi-step orchestration may still require reactive patterns outside the signals paradigm.
