isRefetching result variable

[swain]

It seems like the basic useQuery API should return an isRefetching variable.

This boolean would be true if the data is loading AND it is not the first load (on mount).

A common motivating example: wanting to manage UI around a "pull-to-refresh" behavior.

const { data, isLoading, isRefetching, refetch } = useQuery(...)

return (
  <div>
    { isLoading && !isRefetching
      ? <div>Loading</div>
      : <div>
           {data}
           {
             isRefetching
               ? <div>Refetching</div>
               : <button onClick={() => refetch()}>Refresh</button>
            }
         </div>
      : 
  </div>
);

Seems simple enough to implement -- would a PR be accepted?

It does return isFetching, which is always true when a request is in flight, including the first time (when you are isLoading). So isRefetching is just isFetching && !isLoading
