When to use it

Use Alert for a message that sits in the page: neutral, info, success, warning or destructive, with a title, an action and an optional dismiss. For a passing result, use toast.

Installation

How you get it

Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.

Use Liro's Alert for this.
Install it: npx shadcn@latest add @liro/alert
(the @liro registry is set up in components.json, with LIRO_KEY in .env.local)
Import it from @/components/ui/alert.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.

For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Free components install through the @liro registry with your CLI token: see the Namespaced tab.

Usage

components/billing-alert.tsx
import { Button } from "@/components/ui/button";
import { Alert } from "@/components/ui/alert";

export function BillingAlert({ update }: { update: () => void }) {
  return (
    <Alert
      tone="warning"
      title="Your card expires this month"
      action={<Button size="sm" variant="outline" onClick={update}>Update card</Button>}
    >
      Update it before 14 Nov to keep the Team plan.
    </Alert>
  );
}

Props

Read from the component’s own TypeScript interface when the site is built, so this table cannot drift from the file you install.

TypeNotes
toneAlertTone NoWhat kind of notice it is. Default `info`.
titleReact.ReactNode NoThe headline, one short line.
iconReact.ReactNode | false NoReplace the tone's icon, or pass `false` for none.
actionReact.ReactNode NoOne action: a button or a link, shown under the text on small screens and beside it on wide ones.
onDismiss() => void NoAdds a close button. Called after it is pressed.
dismissLabelstring NoLabel for the close button. Default "Dismiss".
openboolean NoControls whether it shows. Leave it out and a dismissed alert hides itself.
size"sm" | "md" No`sm` for tight spots: inside a card, under a field. Default `md`.

States

All of them are drawn by the component. None is left for you to design.

  • Info
  • Success
  • Neutral
  • Warning
  • Destructive
  • With action
  • Dismissible
  • Compact

Accessibility

  • Keyboard reachable throughout, in visual order
  • Focus trapped in overlays, Escape closes them
  • Focus returns to whatever opened it
  • Live regions announce what changed, not that something did
  • Honours prefers-reduced-motion

Responsive behavior

  • Sizes to its container, not the viewport
  • Usable from 320px up
  • Pointer-based interaction, so trackpad and touch both work
  • No hover-only affordances
