Measured entry
8bitcn-login-form-with-image
A pixel-styled sign-in card with email and password fields, social buttons, legal links, and a responsive image panel. It ships as a shadcn registry block with companion button, card, input, and label wrappers. It depends on shadcn base controls, Tailwind theme utilities, a cn helper, variant and Radix packages, retro CSS, and a hosted font.

What the harness recorded
CONSOLE
Failed to load resource: the server responded with a status of 404 (Not Found)
BARE BUILD
✗ Build failed in 1.03s error during build: [vite]: Rollup failed to resolve import "class-variance-authority" from "<sandbox>re-ae8bc0acd98f/src/components/ui/8bit/input.tsx".
Verdict
Not publishable as supplied. The build fails because the pixel label wrapper imports a base UI label module that is absent, so rendered behavior was never verified. It needs a shadcn-style setup plus that missing primitive. Teams seeking a portable auth form should avoid it until the registry package is fixed.
Use it if
- Your app already has the expected shadcn primitives, aliases, theme tokens, and utility helper.
- You want a retro sign-in shell and will connect submission, recovery, signup, and social login behavior yourself.
- You are prepared to supply the image asset and review the external font import for your deployment policy.
Skip it if
- You need a drop-in form that builds in a plain React project without shadcn infrastructure.
- You need working authentication flows rather than a static interface with placeholder links.
- Your content security or privacy policy does not allow a stylesheet to fetch a hosted Google font.
- You cannot add or repair the missing base label component before integration.
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 the expected source aliases and cn helper, Tailwind utilities and theme tokens, base button, card, input, and label primitives, class-variance-authority, the required Radix packages, and the retro stylesheet. Also provide the placeholder image and decide whether to self-host the font.
