Examples

Success message

Use the success status for a completed task.

success-message.tsx
import { Alert, AlertDescription, AlertTitle } from "@/components/ui/alert"<Alert status="success">  <AlertTitle>Changes saved</AlertTitle>  <AlertDescription>Your profile was updated successfully.</AlertDescription></Alert>

Destructive message

Use the destructive variant for an error message.

destructive-message.tsx
import { Alert, AlertDescription, AlertTitle } from "@/components/ui/alert"<Alert variant="destructive">  <AlertTitle>Payment failed</AlertTitle>  <AlertDescription>Check your payment details and try again.</AlertDescription></Alert>

Warning with an action

Place related content inside AlertAction; it is positioned at the upper right.

warning-with-an-action.tsx
import { Alert, AlertAction, AlertDescription, AlertTitle } from "@/components/ui/alert"<Alert status="warning">  <AlertTitle>Storage almost full</AlertTitle>  <AlertDescription>You are using 90% of your available storage.</AlertDescription>  <AlertAction>    <a href="/storage">Manage</a>  </AlertAction></Alert>

API reference

PropTypeDefaultDescription
AlertReact.ComponentProps<"div"> & VariantProps<typeof alertVariants>—Accepts standard div props, including className and children, plus variant?: "default" | "destructive" | "solid" and status?: "error" | "success" | "warning" | "info". variant defaults to "default". When set, status supplies the alert colors.
AlertTitleReact.ComponentProps<"div">—Accepts standard div props, including className and children. Renders the title content; it does not render a heading element.
AlertDescriptionReact.ComponentProps<"div">—Accepts standard div props, including className and children. Renders the descriptive content.
AlertActionReact.ComponentProps<"div">—Accepts standard div props, including className and children. Positions its content in the alert’s upper-right corner; use an interactive element inside when an action is needed.
alertVariantsVariantProps<typeof alertVariants>—Exported class-variance-authority variant function. Its variant and status options are the same as those accepted by Alert.

Accessibility

  • Alert renders with role="alert", which exposes it as an assertive live region; reserve it for messages that warrant immediate announcement.
  • AlertTitle is a div, not a semantic heading. Choose heading semantics separately if the content structure requires them.
  • AlertAction is a positioned div, not an interactive control. Put a semantic link or button inside it and provide an accessible name.
  • A direct-child SVG is accommodated by the grid layout, but decorative icons should be hidden from assistive technology; provide an accessible name if an icon conveys information not present in the text.
