useIsFetching is an optional hook that returns the number of the queries that your application is loading or fetching in the background (useful for app-wide loading indicators).
import { useIsFetching } from '@tanstack/react-query'
// How many queries are fetching?
const isFetching = useIsFetching()
// How many queries matching the posts prefix are fetching?
const isFetchingPosts = useIsFetching({ queryKey: ['posts'] })
import { useIsFetching } from '@tanstack/react-query'
// How many queries are fetching?
const isFetching = useIsFetching()
// How many queries matching the posts prefix are fetching?
const isFetchingPosts = useIsFetching({ queryKey: ['posts'] })
