Installation#

CLI

npx shadcn@latest add https://hantui-theta.vercel.app/r/dynamic-island.json

Manual

1. Install the dependencies

   npmpnpmbunyarn

   npm install clsx motion tailwind-merge

2. Add the shared helpers

   Components use cn() from lib/utils.ts and the motion tokens below. See Installation if you have not set them up yet.

Usage#

import { DynamicIsland } from "@/components/ui/dynamic-island/dynamic-island";

export function LiveActivity({ upload }: { upload?: number }) {
  return (
    <DynamicIsland view={upload === undefined ? "idle" : "upload"}>
      {upload === undefined ? undefined : <UploadProgress value={upload} />}
    </DynamicIsland>
  );
}

API reference#

Accessibility#

• The island is a plain container; give it role="status" and a label when its content is a live update, as in the example.
• Controls inside expanded activities are ordinary buttons, reachable by keyboard.
• With reduced motion enabled, the island resizes instantly and its content cross-fades without blur or scale.
