useQuery refetch { data } lifecycle

[brantleyenglish]

If a useQuery returns data on the initial load and stores it in data, does it ever replace that value if the next api call returned is an error? Or does it continue to show the data from only the last successful call?

Would running a refetch with queryClient.invalidateQueries(); affect it any differently?

Thanks so much!

Hi 👋

The data that exists in the cache will still be returned by the query if it refetches erroneously. Marking a query as stale via invalidateQueries will exhibit the same behaviour if the query subsequently refetched erroneously.

Hopefully this helps (also, apologies for accidentally closing the discussion; it was an accident!) 🙂
