useIsMutating is an optional hook that returns the number of mutations that your application is fetching (useful for app-wide loading indicators).
import { useIsMutating } from '@tanstack/react-query' // How many mutations are fetching? const isMutating = useIsMutating() // How many mutations matching the posts prefix are fetching? const isMutatingPosts = useIsMutating({ mutationKey: ['posts'] })
import { useIsMutating } from '@tanstack/react-query' // How many mutations are fetching? const isMutating = useIsMutating() // How many mutations matching the posts prefix are fetching? const isMutatingPosts = useIsMutating({ mutationKey: ['posts'] })
