Pixel Block Loader

Install

Or by hand, in a Next.js project with shadcn set up. It writes components/pastetaste/pixel-block-loader.tsx.

Install the pastetaste component "Pixel Block Loader" (pixel-block-loader) into this Next.js project and use it.

What it is: A preloader of randomly vanishing colour blocks over your content with a big percentage counter: timed or driven by real progress, replayable, gone for reduced motion.

Before you place it, ask me (one short message, in my language; "skip" = sensible default): which page and section it goes in, my brand colour (hex), the text, labels or images it should show, and whether I want my logo or my own copy in the demo content. Then:

Steps:
1. If the project has no components.json, run: npx shadcn@latest init -y -d. Then run: npx shadcn@latest add https://pastetaste.com/r/pixel-block-loader.json
   (it writes components/pastetaste/pixel-block-loader.tsx; install any npm packages it reports).
2. Import it: import { PixelBlockLoader } from "@/components/pastetaste/pixel-block-loader" (check the file for the exact named export).
3. Put it where it fits on the page I name, keep the rest of the page untouched, and pass props for my colours instead of editing the installed file.
4. It does not depend on Tailwind; colours come from CSS variables (--pt-*) or props.
5. It supports prefers-reduced-motion with a still state; do not remove it.

Props (all optional unless the type has no default):
- children: ReactNode — The content the blocks uncover.
- cols / rows: number = 16 / 12 — Block grid.
- duration: number = 2.4 — Seconds for 0 to 100 when timed.
- progress: number — 0 to 100 to drive it manually; overrides the timer.
- colors / ink / paper: string[] / string / string = paper greys + ink — Block palette, counter colour and counter pill background.
- label / runKey / onDone: string / number / () => void = Loading / 0 — Counter caption, replay trigger, completion callback.
- className / style: string / CSSProperties — On the root.

Then run the dev server, check it in the browser at desktop and mobile width, and tell me the page URL.
