Measured entry
8bitcn-not-found2
A full-page retro not-found block for Next.js, shipped through a shadcn registry with a pixel-art dwarf, configurable copy, link, and image. It uses Next Link and Image, Tailwind theme classes, a cn helper, a Google-hosted pixel font, and an 8bit button layered over the standard shadcn button.

What the harness recorded
CONSOLE
Failed to load resource: the server responded with a status of 404 (Not Found)
BARE BUILD
✗ Build failed in 1.04s error during build: [vite]: Rollup failed to resolve import "class-variance-authority" from "<sandbox>re-3c3e63b53289/src/components/ui/8bit/button.tsx".
Verdict
The harness build fails because the bundled themed button imports a base UI button that the registry does not supply. It needs a shadcn-style setup, and teams wanting a portable drop-in block should avoid it until that dependency is repaired.
Use it if
- Your Next.js app already uses shadcn conventions and you want a themed not-found route.
- You can provide the dwarf image asset and accept a remotely loaded display font.
- Your product already has a retro or pixel-art visual language.
Skip it if
- You need a registry item that builds without repairing missing internal UI imports.
- Your app is not based on Next.js or does not use its Link and Image components.
- Your content security policy or offline requirements prohibit the Google font import.
- A playful dwarf illustration would conflict with the tone of an error page.
Install
| Declared dependencies | radix-ui, clsx, tailwind-merge |
|---|---|
| Missing on install | none |
| Bare install | fails once the shadcn-style helpers are removed, so it needs that setup |
| Provider | no provider required in the harness |
In a non-shadcn project, add a compatible base button, the cn class-merging helper, matching import aliases and Tailwind theme tokens, Radix Slot, class-variance-authority, the retro stylesheet and font access, plus the dwarf image. Adapt the Next Link and Image usage if the app uses another framework.
