3 In-Depth TopicsState Management Patterns
Modern frontend state management separates concerns into local component state, server cache (TanStack Query), URL state (search params), and lightweight client stores (Zustand) — each optimized for different access patterns.
TanStack Query & Server State Management
TanStack Query (React Query) is a dedicated server-state management library providing declarative data fetching, automatic caching, deduplication, background revalidation (SWR), and garbage collection.
Optimistic UI Updates & Rollback Strategies
Optimistic UI is an interaction design and architectural pattern where the client updates local state immediately assuming a server mutation will succeed, and cleanly rolls back state with user feedback if the mutation fails.
