This skill provides comprehensive knowledge for TanStack Query v5 (React Query) server state management in React applications. It should be used when setting up data fetching with useQuery, implementing mutations with useMutation, configuring QueryClient, managing caching strategies, migrating from v4 to v5, implementing optimistic updates, using infinite queries, or encountering query/mutation errors. Use when: initializing TanStack Query in React projects, configuring QueryClient settings, creating custom query hooks, implementing mutations with error handling, setting up optimistic updates, using useInfiniteQuery for pagination, migrating from React Query v4 to v5, debugging stale data issues, fixing caching problems, resolving v5 breaking changes, implementing suspense queries, or setting up query devtools. Keywords: TanStack Query, React Query, useQuery, useMutation, useInfiniteQuery, useSuspenseQuery, QueryClient, QueryClientProvider, data fetching, server state, caching, staleTime, gcTime, query invalidation, prefetching, optimistic updates, mutations, query keys, query functions, error boundaries, suspense, React Query DevTools, v5 migration, v4 to v5, request waterfalls, background refetching, cacheTime renamed, loading status renamed, pending status, initialPageParam required, keepPreviousData removed, placeholderData, query callbacks removed, onSuccess removed, onError removed, object syntax required

Provides comprehensive knowledge for TanStack Query v5 (React Query) server state management in React applications, including setup, queries, mutations, caching strategies, v4→v5 migration, optimistic updates, infinite queries, and error handling.
✅ QueryClient configuration and setup ✅ useQuery, useMutation, useInfiniteQuery patterns ✅ Optimistic updates and cache management ✅ v4 to v5 migration (all breaking changes) ✅ TypeScript patterns and type safety ✅ Error handling strategies ✅ Caching and refetching strategies ✅ DevTools setup and debugging ✅ Testing patterns with MSW
| Issue | Why It Happens | Source | How Skill Fixes It |
|-------|---------------|---------|-------------------|
| #1: Object Syntax Required | v5 removed function overloads | Migration Guide | Always use useQuery({ queryKey, queryFn }) |
| #2: Query Callbacks Removed | onSuccess/onError removed from queries | v5 Breaking Changes | Use useEffect or move to mutations |
| #3: Status Renamed | loading → pending | v5 Migration | Use isPending for initial load |
| #4: cacheTime → gcTime | Renamed for clarity | v5 Migration | Use gcTime instead |
| #5: useSuspenseQuery + enabled | enabled option not available | GitHub #6206 | Use conditional rendering |
| #6: initialPageParam Required | v5 requires explicit value | v5 Migration | Always provide initialPageParam |
| #7: keepPreviousData Removed | Replaced with placeholderData | v5 Migration | Use placeholderData: keepPreviousData |
| #8: Error Type Default | Changed from unknown to Error | v5 Migration | Specify error type if non-Error |
# Install dependencies
npm install @tanstack/react-query@latest
npm install -D @tanstack/react-query-devtools@latest
# Set up QueryClient Provider (see SKILL.md for complete setup)
