TanStack Query Core

To manage async server state in React, use a caching layer with stable query keys and declarative data-fetching. This approach reduces boilerplate, prevents stale data, and enables predictable refetch behavior across shared components.

The best way to configure type-safe data fetching is using a Query Options API. It defines reusable configurations with queryKey and queryFn, ensuring stable caching and type safety across components that share data.

You organize related queries by implementing query factories. Factories group shared configurations and query keys, allowing multiple components to reuse the same data-fetching logic while maintaining predictable refetch behavior.

Caching handles background updates by keeping dashboards and lists fresh automatically. Stable query keys maintain cached data while background updates fetch new information, reducing extra work and avoiding stale displays.

Yes, you can use useQuery to fetch data with stable keys across shared components. It leverages queryKey-based caching to ensure data is shared predictably and background updates keep the UI fresh.

You need query factories when managing server state across multiple components sharing similar data. Factories organize related queries, share configurations, and maintain stable queryKey-based caching to prevent stale data.
