+```ts
+function useIsFetching(filters?, queryClient?): Accessor<number>;
+```
+
+Defined in: [packages/solid-query/src/useIsFetching.ts:29](https://github.com/TanStack/query/blob/main/packages/solid-query/src/useIsFetching.ts#L29)
+
+The `useIsFetching` hook returns the `number` of the queries that your application is loading or fetching
+in the background (useful for app-wide loading indicators).
+
+## Parameters
+
+### filters?
+
+`Accessor`\<[`QueryFilters`](../interfaces/QueryFilters.md)\<readonly `unknown`[]\>\>
+
+An accessor returning the [QueryFilters](../interfaces/QueryFilters.md) to narrow down the matched queries.
+
+### queryClient?
+
+`Accessor`\<[`QueryClient`](../classes/QueryClient.md)\>
+
+An accessor for a custom `QueryClient`. Otherwise, the one from the nearest context
+will be used.
+
+## Returns
+
+`Accessor`\<`number`\>
+
+An accessor for the `number` of the queries that your application is currently loading or fetching
+in the background.
+
+## Example
+
+```tsx
+import { useIsFetching } from '@tanstack/solid-query'
+
+function GlobalLoadingIndicator() {
+  // How many queries matching the posts prefix are fetching?
+  const isFetchingPosts = useIsFetching(() => ({ queryKey: ['posts'] }))
+
+  return isFetchingPosts() > 0 ? <span>Loading posts...</span> : null
+}
+```
