ROBUST DATA FETCHING ARCHITECTURE FOR COMPLEX REACT/NEXT.JS APPS

Summary from the TLDR Web Dev newsletter

A three-layer architecture can solve common data fetching problems in React apps. Layer 1 uses Server Components for initial data loading, Layer 2 uses React Query for client-side caching and updates, and Layer 3 uses optimistic updates for instant UI feedback. This separation of concerns prevents the typical issues that come from naive approaches (like scattered useEffect hooks), keeping components clean and focused on rendering.
