TanStack Query v5 migration requires adopting the new object syntax for useQuery, passing a single arguments object instead of separate parameters to resolve syntax errors from v4.

Optimistic updates in TanStack Query are implemented by leveraging the new useMutationState feature, allowing you to immediately reflect changes in the UI before the server confirms the mutation.

The best way to handle offline support in React Query is by configuring network modes, which dictate how queries and mutations behave when a network connection is unavailable or unstable.

throwOnError in TanStack Query v5 works by propagating query errors to the nearest error boundary, allowing you to declaratively handle application-wide errors instead of manually checking state flags.

You configure infinite queries in React by utilizing TanStack Query's infinite query hook to manage pagination, which automatically handles fetching additional pages and appending them to the existing list.

Callbacks were removed in TanStack Query v5 to simplify the API and encourage the use of effects for side effects; you adapt by moving logic to useEffect or mutation callbacks.
