Angular 22, released June 3 2026, marks the completion of the framework's two-year signals migration. The Resource API (resource(), rxResource(), httpResource()) and Signal Forms have graduated from experimental to stable. The post walks through practical usage of each resource primitive with code examples: resource() for generic async work, rxResource() for observable-based sources, and httpResource() as a shortcut for REST calls. A new debounced() utility is introduced, enabling RxJS-free debounced search inputs with built-in loading states. Unit testing patterns using TestBed, fakeAsync, and tick() are also covered, showing how signal-based components are simpler to test than RxJS-heavy ones.
