SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Angular core patterns like standalone components, signals, and zoneless workflows are hard to implement consistently across projects. This Skill captures the recommended approaches so teams can apply them uniformly and boost developer productivity.

Core Features & Use Cases

  • Standalone Components: adopt component-by-default patterns, avoiding unnecessary NgModule boilerplate.
  • Signals for state: apply signal, computed, and effect-based state management to replace traditional lifecycle hooks.
  • inject() over constructor: prefer inject() for dependency access to improve testability and readability.
  • Zoneless Angular: enable zoneless change detection via provideZonelessChangeDetection() and bootstrap patterns.
  • Lifecycle guidance: avoid onInit/onChanges/onDestroy in favor of signals and effects for cleanup.
  • RxJS when needed: reserve RxJS for complex async scenarios while preferring signals for simple state.

Quick Start

Implement the Angular core patterns by converting components to standalone components, wiring state with signals, and enabling zoneless change detection.

FAQPage Schema
How do I replace Angular lifecycle hooks with signals for state management?

Angular signals replace lifecycle hooks by applying signal, computed, and effect-based state management, avoiding onInit, onChanges, and onDestroy for reactive state updates and cleanup.

What is the best way to set up zoneless change detection in Angular?

Zoneless change detection is set up by enabling provideZonelessChangeDetection() during bootstrap, removing reliance on Zone.js for rendering cycles across standalone components.

Does this Angular approach require standalone components to work?

Yes, the approach adopts component-by-default standalone patterns, removing NgModule boilerplate and serving as the foundation for applying signals and inject() workflows.

Why use inject() instead of constructor injection in Angular components?

Using inject() replaces constructor injection to improve readability and testability when accessing dependencies within standalone components.

When should I use RxJS instead of signals for async logic?

RxJS is reserved for complex asynchronous scenarios, while signals are preferred for simple state management to enforce lifecycle-free workflows across components.

Can I replace @Input and @Output decorators with signals in Angular?

Yes, the pattern replaces @Input and @Output decorators with signals to manage component inputs and outputs within a zoneless, lifecycle-free architecture.
