To fetch HTTP data in Angular using signals, utilize the httpResource() and resource() functions to automatically retrieve API data and refetch when parameters change. This approach converts Observable-based HttpClient calls into Signals for seamless reactive UI updates.

Handling loading and error states with httpResource involves binding the built-in loading, error, and value state accessors directly to your component template. This provides automatic UI updates across data fetching, error handling, and parameter transformations without manual state tracking.

Yes, you can use HttpClient interceptors for authentication with signal-based resources. The Skill supports standard HttpClient interceptors, allowing you to centralize auth, error handling, and logging while fetching data through resource() and httpResource() functions.

To convert Observable-based HttpClient calls to Signals across Angular components, implement the resource() or httpResource() wrapper. This pattern transforms your existing API calls into signal-based resources, enabling reactive data loading that automatically updates the UI when dependencies shift.

Yes, httpResource automatically refetches API data when bound parameters change. By configuring signal-based resources with HttpClient, the system detects parameter updates and triggers a new request, maintaining reactive data loading without requiring manual subscription management.
