404 With Redirect Countdown

Installation

A real shadcn registry command, not a copy-paste stand-in: it fetches this block plus its button dependencies and any missing npm packages, and installs them straight into your project.

Prefer not to use the CLI? Copy the source from the Code toggle above into src/components/blocks/error/error8.tsx instead.

Usage

The file also exports error8Demo, the exact props behind the preview above. Spread it to get a working section in one line, then replace it with your own data.

import { Error8, error8Demo } from "@/components/blocks/error/error8";

export default function Page() {
  return <Error8 {...error8Demo} />;
}

Props

Behavior notes

• The countdown is a real client-side timer: a setInterval created in useEffect decrements local state once per second; when it reaches zero it clears itself and calls onRedirect exactly once, guarded by a ref so a later re-render can't call it twice.
• Cancel is a real handler: it clears the interval (via the effect's cleanup) and swaps the countdown text for a static "cancelled" message, no further ticking happens after that.
• "Go now" is a real Next.js Link via the button's render prop that navigates to redirectHref immediately if clicked, it does not itself call onRedirect, that callback only fires from the countdown reaching zero.
