# Alert dialog: Async action

> Return a promise from the `onClick` of `<AlertDialogAction />`. The button shows a spinner and the dialog can’t be closed until the promise settles. It closes when it resolves and stays open when it rejects, so people can try again.

Example: https://hextaui.com/docs/alert-dialog/examples/async-action
Component docs: https://hextaui.com/docs/alert-dialog.md

## Add this example

```bash
npx shadcn@latest add https://hextaui.com/r/alert-dialog-async-action.json
```

This adds `components/examples/alert-dialog/async-action.tsx` with the Alert dialog component and the HextaUI theme tokens.
