SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps developers produce idiomatic, maintainable Angular code by enforcing modern Angular (17+) patterns and avoiding common anti-patterns that lead to bugs, performance issues, and harder-to-test components.

Core Features & Use Cases

  • Standalone components by default: build new components without NgModules and leverage imports inside @Component.
  • Signals-first state management: use signal, computed, and effect for predictable component state while reserving RxJS for asynchronous streams.
  • Angular-native DI and typing: prefer inject() in standalone contexts, abstract services behind interfaces, and use typed reactive forms (FormControl<string>, FormGroup).
  • Centralized error handling: implement global ErrorHandler and HTTP interceptors, and ensure RxJS pipelines handle errors instead of leaving subscriptions unguarded.
  • Testing-friendly patterns: use Angular Testing Library for component tests, Spectator for services, and HttpTestingController for HTTP tests.

Quick Start

Apply the Angular Idioms and Patterns skill to your component and route code, then refactor state to signals, replace manual lifecycle wiring where appropriate, and ensure errors are handled via interceptors and guarded RxJS pipelines.

Frequently Asked Questions about Angular Idioms and Patterns

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I write idiomatic Angular components using signals?▼

To write idiomatic Angular components, use signals with computed values and effects for predictable state management, prefer standalone components, and reserve RxJS strictly for asynchronous streams to improve maintainability.

What is the best way to handle RxJS errors in Angular?▼

The best way to handle RxJS errors in Angular is by implementing centralized error handling using global ErrorHandler and HTTP interceptors, ensuring RxJS pipelines actively handle errors instead of leaving subscriptions unguarded.

How do I use dependency injection in standalone Angular components?▼

To use dependency injection in standalone Angular components, utilize the inject() function within standalone contexts, abstract services behind interfaces, and ensure typed reactive forms like FormControl and FormGroup are applied.

Does this Angular idiom approach support typed reactive forms?▼

Yes, this Angular idiom approach supports typed reactive forms by enforcing strict typing with FormControl and FormGroup, seamlessly integrating with inject-based dependency injection and standalone component architectures.

How to test Angular services and HTTP workflows effectively?▼

To test Angular services and HTTP workflows effectively, utilize Spectator for service testing and HttpTestingController for HTTP tests, applying Angular Testing Library for component tests within modern standalone architectures.
