To migrate React data fetching from v4 to v5, adopt the enforced object syntax for hooks, replace cacheTime with gcTime, and update to the initial pending state semantics. Type-safe error handling for queries and mutations is also required.

Cross-component mutation tracking uses the useMutationState hook to monitor pending mutations across your React application. This allows you to observe mutation states globally without manually passing props between components.

Yes, TanStack Query v5 supports SSR hydration debugging and network mode options for online or offline environments. These features ensure reliable server state management and data fetching consistency across varying network conditions.

The best way to manage infinite queries is using the infiniteQueryOptions helper to simplify complex query patterns. This approach standardizes pagination logic and integrates seamlessly with TanStack Query's unified server state caching.

Your React query cache behavior changed because v5 enforces gcTime-based cache management, replacing the previous cacheTime property. This update alters garbage collection timing and requires object-style syntax for all hook configurations.
