useQuery deduplication occurs when multiple React components use the same query key, allowing TanStack Query to share a single network request and cache across the component tree.

You can create custom hooks wrapping useQuery to centralize query configuration, promote configuration reuse, and maintain robust data fetching with minimal boilerplate across your application.

The best way to minimize re-renders is using the select option in useQuery to subscribe components only to specific UI slices, optimizing performance by preventing unnecessary component updates.

You should use co-located queries directly in components when you want maximum portability and automatic deduplication, trading off centralized control for robust, maintainable data fetching with less boilerplate.

Yes, TanStack Query supports the select option to perform data transformation, allowing each component to subscribe to specific slices of the cached data and significantly optimize rendering performance.
