Alert Dialog

A modal dialog that interrupts the user with important content and expects a response.

import {
  AlertDialog,
  AlertDialogCancel,
  AlertDialogContent,
  AlertDialogDescription,
  AlertDialogFooter,
  AlertDialogHeader,
  AlertDialogTitle,
  AlertDialogTrigger,
} from '@/components/ui/alert-dialog';
import { Button } from '@/components/ui/button';

export default function AlertDialogDemo() {
  return (
    <AlertDialog>
      <AlertDialogTrigger render={<Button variant="outline" />}>
        Delete account
      </AlertDialogTrigger>
      <AlertDialogContent>
        <AlertDialogHeader>
          <AlertDialogTitle>Are you absolutely sure?</AlertDialogTitle>
          <AlertDialogDescription>
            This action cannot be undone. This will permanently delete your
            account and remove your data from our servers.
          </AlertDialogDescription>
        </AlertDialogHeader>
        <AlertDialogFooter>
          <AlertDialogCancel>Cancel</AlertDialogCancel>
          <AlertDialogCancel variant="destructive">Delete</AlertDialogCancel>
        </AlertDialogFooter>
      </AlertDialogContent>
    </AlertDialog>
  );

Destructive action

Use AlertDialogAction (a plain Button) instead of AlertDialogCancel when the confirming action needs to run async work — like this delete request — before the dialog closes.

'use client';

import * as React from 'react';

import {
  AlertDialog,
  AlertDialogAction,
  AlertDialogCancel,
  AlertDialogContent,
  AlertDialogDescription,
  AlertDialogFooter,
  AlertDialogHeader,
  AlertDialogTitle,
  AlertDialogTrigger,
} from '@/components/ui/alert-dialog';
import { Button } from '@/components/ui/button';
import { Spinner } from '@/components/ui/spinner';

function deleteAccount() {
  return new Promise<void>((resolve) => setTimeout(resolve, 1500));
}

export default function AlertDialogDestructive() {
  const [open, setOpen] = React.useState(false);
  const [deleting, setDeleting] = React.useState(false);

  async function handleDelete() {
    setDeleting(true);
    await deleteAccount();
    setDeleting(false);
    setOpen(false);
  }

  return (
    <AlertDialog open={open} onOpenChange={setOpen}>
      <AlertDialogTrigger render={<Button variant="destructive" />}>
        Delete account
      </AlertDialogTrigger>
      <AlertDialogContent>
        <AlertDialogHeader>
          <AlertDialogTitle>Delete your account?</AlertDialogTitle>
          <AlertDialogDescription>
            This action cannot be undone. This will permanently delete your
            account and remove your data from our servers.
          </AlertDialogDescription>
        </AlertDialogHeader>
        <AlertDialogFooter>
          <AlertDialogCancel disabled={deleting}>Cancel</AlertDialogCancel>
          <AlertDialogAction
            variant="destructive"
            disabled={deleting}
            onClick={handleDelete}
          >
            {deleting && <Spinner />}
            {deleting ? 'Deleting…' : 'Delete account'}
          </AlertDialogAction>
        </AlertDialogFooter>
      </AlertDialogContent>
    </AlertDialog>
  );
}

Built on Base UI Alert Dialog. The tables below cover the props this library adds or changes — every other prop is forwarded to the underlying Base UI part; see the Base UI Alert Dialog API reference.

AlertDialogContent

Prop	Type	Default	Description
`size`	`'md' \| 'sm'`	`'md'`	`sm` is narrower and keeps the footer buttons in a two-column grid.
`style`	`StyleXStyles`	—	StyleX styles merged last — always win over the component’s own styles.

AlertDialogAction

A plain Button (accepts variant, size). Wire your own onClick and close via the dialog’s open state, so destructive actions can await work first.

AlertDialogCancel

Base UI Close rendered as a Button.

Prop	Type	Default
`variant`	`ButtonVariant`	`'outline'`
`size`	`ButtonSize`	`'md'`
