Banner Countdown Flash Sale

Installation

A real shadcn registry command, not a copy-paste stand-in: it fetches this block plus its 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/banner/banner3.tsx instead.

Usage

The file also exports banner3Demo, 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 { Banner3, banner3Demo } from "@/components/blocks/banner/banner3";

export default function Page() {
  return <Banner3 {...banner3Demo} />;
}

Props

Behavior notes

• The countdown is null on first render (server and pre-hydration client both show "00" in every unit) and only fills in with real numbers after useEffect runs on mount, so the initial render is deterministic and never mismatches during hydration.
• The interval re-derives all four units from targetDate every second rather than decrementing local counters, so it self-corrects if the tab was backgrounded and drifted.
• Remaining time is clamped at zero via Math.max; past the target date every unit renders 00 instead of going negative.
