SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It solves the confusion and inconsistency that teams face when building Angular components, especially when adopting modern patterns like standalone components, signals, inject-based dependency access, and zoneless change detection.

Core Features & Use Cases

  • Standalone-first Angular architecture: Encourages component patterns suitable for modern Angular apps, including OnPush and clean separation of concerns.
  • Signal-based state management: Recommends signals, computed, and effect for reactive UI state instead of lifecycle-driven patterns.
  • Zoneless Angular setup: Guides adding zoneless change detection via provideZonelessChangeDetection and removing Zone.js assumptions.
  • Preferred template and API boundaries: Enforces external templates and function-based input/output APIs to keep component code maintainable.

Use Case: You are creating a production Angular feature component and want reliable reactive behavior using signals, clean templates, and a zoneless runtime configuration without legacy lifecycle complexity.

Quick Start

Use the angular-core skill to generate an Angular component that uses standalone patterns, signals-based state, inject() for services, and zoneless change detection.

Frequently Asked Questions about angular-core

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

FAQPage Schema
How do I set up zoneless Angular components with signals?▼

Set up zoneless Angular by configuring provideZonelessChangeDetection and using signals with computed and effect for reactive state. This removes Zone.js dependencies and reduces lifecycle complexity in standalone components.

What is the best way to manage Angular state without lifecycle hooks?▼

The best way to manage Angular state without lifecycle hooks is using signal-first logic with signals, computed, and effect. This approach replaces legacy lifecycle-driven patterns with reactive state management for standalone components.

Do I need external HTML templates for standalone Angular components?▼

Yes, you need external HTML templates for standalone Angular components. Using external templates enforces preferred API boundaries and maintains clean separation of concerns when building components with function-based inputs and outputs.

Can I use inject-based dependencies in Angular with OnPush change detection?▼

Yes, you can use inject-based dependencies in Angular with OnPush change detection. Inject-based dependency access works with standalone components, signals, and zoneless execution scenarios to maintain clean reactive behavior.

How does Angular template control flow syntax work with zoneless execution?▼

Angular template control flow syntax works with zoneless execution by leveraging signals for reactive updates instead of Zone.js. This combination in standalone components ensures consistent UI rendering without manual change detection triggers.

What are the limitations of using signals and zoneless change detection in Angular?▼

Limitations of using signals and zoneless change detection in Angular include removing all Zone.js assumptions and requiring function-based input/output APIs. You must also use external templates and configure provideZonelessChangeDetection properly.
