isFetched boolean Will be true if the query has been fetched. -
isFetchedAfterMount boolean Will be true if the query has been fetched after the component mounted. - This property can be used to not show any previously cached data. -
isFetching boolean A derived boolean from the fetchStatus variable, provided for convenience. - true whenever the queryFn is executing, which includes initial pending as well as background refetch. -
isInitialLoading boolean Deprecated isInitialLoading is being deprecated in favor of isLoading and will be removed in the next major version. -
isLoading false Is true whenever the first fetch for a query is in-flight. - Is the same as isFetching && isPending. QueryObserverBaseResult.isLoading
