+
+Injects a signal that tracks the number of queries that your application is loading or fetching in the
+background (useful for app-wide loading indicators).
+
+## Parameters

+
+[`QueryFilters`](../interfaces/QueryFilters.md)\<readonly `unknown`[]\>

+[`InjectIsFetchingOptions`](../interfaces/InjectIsFetchingOptions.md)
+
+Additional configuration
+
+## Returns
+
+`Signal`\<`number`\>
+
+A `Signal` with the number of queries that your application is currently loading or fetching in
+the background.
+
+## Examples
+
+```angular-ts
+@Component({
+  selector: 'posts-fetching-indicator',
+  template: `
+    @if (isFetchingPosts()) {
+      <span>Refreshing posts...</span>
+    }
+  `,
+})
+export class PostsFetchingIndicator {
+  // How many queries matching the posts prefix are fetching?
+  readonly isFetchingPosts = injectIsFetching({ queryKey: ['posts'] })
+}
+```
+
+A global loading indicator for any query fetching in the background, not just the ones on screen:
+```angular-ts
+@Component({
+  selector: 'global-loading-indicator',
+  template: `
+    @if (isFetching()) {
+      <div>Queries are fetching in the background...</div>
+    }
+  `,
+})
+export class GlobalLoadingIndicator {
+  readonly isFetching = injectIsFetching()
+}
+```
