TanStack Query Patterns

Purpose

Modern data fetching with TanStack Query v5 (latest: 5.90.5, November 2025), emphasizing Suspense-based queries, cache-first strategies, and centralized API services.

Note: v5 (released October 2023) has breaking changes from v4:

• isLoading → isPending for status
• cacheTime → gcTime (garbage collection time)
• React 18.0+ required
• Callbacks removed from useQuery (onError, onSuccess, onSettled)
• keepPreviousData replaced with placeholderData function
