SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It simplifies fetching data from APIs in Angular by providing reactive, signal‑based helpers that handle loading, errors, and caching automatically.

Core Features & Use Cases

Signal‑based httpResource: automatically manages request lifecycle and state.
Generic resource(): supports custom async operations with reactive parameters.
Traditional HttpClient: usable with toSignal conversion for observable handling.
Interceptors: easy setup for authentication, logging, and error handling.
Patterns: includes pagination, file upload, caching, and request cancellation strategies.

Quick Start

Use the angular-http skill to retrieve the user profile from /api/users/123 with a single command.

FAQPage Schema

How do I fetch HTTP data using Angular signals?▼

Fetch HTTP data using Angular signals by leveraging httpResource or generic resource() helpers. These automatically manage the request lifecycle, reactive loading state, and error handling within Angular v20+ components and services.

What is the best way to handle loading state and errors in Angular HTTP requests?▼

The best way to handle loading state and errors is using signal-based httpResource. It automatically tracks reactive loading states and manages error handling natively without requiring manual observable subscriptions.

Can I use traditional HttpClient with Angular signals?▼

Yes, you can use traditional HttpClient with Angular signals. Convert observable-based responses into reactive signals using the toSignal conversion utility to maintain compatibility with existing data fetching patterns.

Does this approach support HTTP interceptors for authentication and logging?▼

Yes, signal-based HTTP fetching supports interceptors. You can easily configure interceptors for authentication, logging, and centralized error handling across your Angular application's API requests.

How do I implement pagination and caching with httpResource in Angular?▼

Implement pagination and caching with httpResource by applying provided reactive patterns. The skill includes specific strategies for file uploads, caching, and request cancellation to optimize API data fetching.

Do I need Angular v20 to use signal-based HTTP resources?▼

Yes, you need Angular v20 or higher. Signal-based resources like httpResource and generic resource() are designed specifically for Angular v20+ components and services to enable reactive API fetching.
