Prefetching queries in React Query loads data in advance before users navigate to a page or trigger an action, creating a seamless experience with instant data display. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented prefetching strategies in data-heavy admin dashboards throughout my 11 years of React development. The most effective approach is using queryClient.prefetchQuery in event handlers or navigation logic to load data proactively. This method populates the cache before components mount, eliminating loading states for better user experience.

Query invalidation in React Query forces refetching of stale data after mutations, ensuring the UI stays synchronized with server state without manual cache updates. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented query invalidation patterns in admin dashboards throughout my 11 years of React development. The most reliable approach is using queryClient.invalidateQueries in mutation callbacks to automatically refetch affected data. This method maintains data consistency across components without complex state synchronization logic.

React Query simplifies server state management by handling caching, synchronization, and background updates automatically, eliminating the need for manual data fetching logic. As the creator of CoreUI, a widely used open-source UI library, I’ve integrated React Query in complex data-driven applications throughout my 11 years of React development. The most effective approach is wrapping your app with QueryClientProvider and using the useQuery hook for data fetching. This method provides automatic caching, background refetching, and loading states out of the box.
