Use cache when refetching if a condition is met?

[1Computer1]

Hello, suppose I have two fetchers, fetchLastModified and fetchExpensive.
I would like to be able to do something like this:

const { data: lastModified, isSuccess } = useQuery('lastModified', fetchLastModified);
const { data } = useQuery('expensive', fetchExpensive, {
  enabled: isSuccess,
  useCache: lastModified > lastLastModified, // Something like this?
});

The idea is that if nothing is in cache, it would fetch, but if there is something in cache and the condition is met, then it would not refetch (incl. on refocus and such). Perhaps there is a manual way to implement this logic?

Thanks!

Take a look at this part of RQ docs

That seems to only work on the initial fetch, not on subsequent refetches?

what do you mean subsequent refetches? If you pair initialData with staleTime, this should be pretty much what you need.
