This brings TanStack Query's server state management to Angular with a signals-based API that's native to Angular's reactivity model. Use it when you're tired of manually managing loading states, caching, and refetching logic for API calls. The injectQuery and injectMutation functions replace the old Observable patterns with signal primitives that work cleanly in templates. Version 5 is still experimental but the API is solid: query options for reusable configs, built-in DevTools, and optimistic updates that actually feel ergonomic. If you're building data-heavy Angular apps and want declarative data fetching that doesn't fight the framework, this is the right tool.
