Background Fetching Indicators

A query's status === 'loading' state is sufficient enough to show the initial hard-loading state for a query, but sometimes you may want to display an additional indicator that a query is refetching in the background. To do this, queries also supply you with an isFetching boolean that you can use to show that it's in a fetching state, regardless of the state of the status variable:

function Todos() {
const { status, data: todos, error, isFetching } = useQuery({
queryKey: ['todos'],
queryFn: fetchTodos,
return status === 'loading' ? (
) : status === 'error' ? (
<span>Error: {error.message}</span>
) : (
{isFetching ? <div>Refreshing...</div> : null}
{todos.map(todo => (
<Todo todo={todo} />

Displaying Global Background Fetching Loading State

In addition to individual query loading states, if you would like to show a global loading indicator when any queries are fetching (including in the background), you can use the useIsFetching hook:

import { useIsFetching } from '@tanstack/react-query'
function GlobalLoadingIndicator() {
const isFetching = useIsFetching()
return isFetching ? (
<div>Queries are fetching in the background...</div>
) : null
