TanStack Query v5 data fetching patterns including useSuspenseQuery, useQuery, mutations, cache management, and API service integration. Use when fetching data, managing server state, or working with TanStack Query hooks.
TanStack Query v5 performance optimization for data fetching, caching, mutations, and query patterns. This skill should be used when using useQuery, useMutation, queryClient, prefetch patterns, or TanStack Query caching. This skill does NOT cover generating query hooks from OpenAPI (use orval skill) or mocking API responses in tests (use test-msw skill).
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
TanStack Query (React Query) patterns for data fetching, caching, mutations, and optimistic updates. Use when implementing server state management, API caching, or data synchronization in React applications.
Advanced TanStack Query v5 patterns for infinite queries, optimistic updates, prefetching, gcTime, and queryOptions. Use when building data fetching, caching, or optimistic updates.
Manage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.
Use when integrating next-safe-action with TanStack Query (React Query) -- mutationOptions(), useMutation, ActionMutationError error handling, type guards, optimistic updates via query cache, query invalidation after mutations
TanStack Query v5 expert guidance - migration gotchas (v4→v5 breaking changes), performance pitfalls (infinite refetch loops, staleness traps), and decision frameworks (when NOT to use queries, SWR vs React Query trade-offs). Use when: (1) debugging v4→v5 migration errors (gcTime, isPending, throwOnError), (2) infinite refetch loops, (3) SSR hydration mismatches, (4) choosing between React Query vs SWR vs fetch, (5) optimistic update patterns not working. NOT for basic setup (see official docs). Focuses on non-obvious decisions and patterns that cause production issues. Triggers: React Query, TanStack Query, v5 migration, refetch loop, stale data, SSR hydration, query invalidation, optimistic updates debugging.
Build, review, debug, migrate, or plan TanStack Query v5 React server-state code with current docs. Use for @tanstack/react-query, QueryClient, QueryClientProvider, useQuery, useMutation, useInfiniteQuery, useQueries, queryOptions, mutationOptions, query keys, cache defaults, staleTime, gcTime, invalidation, optimistic updates, SSR, hydration, prefetching, router integration, suspense, persistence, devtools, ESLint rules, testing, TypeScript, and v4-to-v5 migrations.
Current TanStack Query v5 guidance for queries, mutations, caching, prefetching, Suspense, and render optimization. Use with useQuery, useMutation, queryClient, queryOptions, skipToken, mutation scopes, or cache invalidation. API mocking is covered by the msw skill.
Generate TanStack Query hooks for efficient server state management. Creates query hooks, mutation hooks with automatic cache invalidation, and handles loading/error states. Use when fetching data from APIs or databases in React components.
TanStack Query (React Query) for async operations, data fetching, caching, and state management. Use when fetching server data, managing async operations, caching responses, handling mutations, or any operation that benefits from automatic state management and caching.
