Announcement Banner
A message, an optional link and a close button. Closing it is remembered in the browser under a key you choose, so a returning visitor is not shown it again. Three tones: default, accent and warning.
The decision inside it
Closing it is remembered per announcement
Give each announcement its own storage key; a new one shows again even to someone who closed the last one, and a blocked storage never breaks the page.
When to use it
Use Announcement Banner for one line across the top of a site: a launch, a notice, planned maintenance. Give each announcement its own storageKey so closing it is remembered. For a message about one action, use a 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 Layro's Announcement Banner for this.
Install it: npx shadcn@latest add @layro/announcement-banner
(the @layro registry is set up in components.json, with LAYRO_KEY in .env.local)
Import it from @/components/ui/announcement-banner.
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 @layro registry with your CLI token: see the Namespaced tab.
Usage
import { AnnouncementBanner } from "@/components/ui/announcement-banner";

return (
<AnnouncementBanner
tone="accent"
message="Templates marketplace is live."
action={{ label: "Browse templates", href: "/templates" }}
dismissible
storageKey="banner-templates-launch"
/>
);

Props
