Measured entry

8bitcn-theme-selector

selectskeuomorphism

A shadcn registry theme picker for Next.js that ships a dropdown, theme context, URL and cookie synchronization, an 8bit Select wrapper, and global theme CSS. It depends on React, Next.js navigation, nuqs, path aliases, and the base shadcn Select primitive.

What the harness recorded

BARE BUILD

✗ Build failed in 1.32s
error during build:
[vite]: Rollup failed to resolve import "class-variance-authority" from "<sandbox>re-bd18b291539c/src/components/ui/8bit/select.tsx".

Verdict

Do not publish this as working yet. The build fails because the 8bit Select wrapper imports a base local Select module that was not installed. It needs a shadcn-style setup, and teams unwilling to repair that registry dependency should avoid it.

Use it if

  • You already use the 8bitcn theme classes and want visitors to switch among them.
  • Your Next.js app should persist a theme in a cookie and expose the choice in a shareable query string.
  • You are comfortable installing and maintaining the registry's supporting Select primitive and global CSS.

Skip it if

  • You need a drop-in component that builds without shadcn registry dependencies.
  • Your app is not on Next.js and you do not want to replace its navigation and URL-state integration.
  • You do not want a selector that mutates global document classes and writes a preference cookie.
  • You only need a light and dark toggle rather than the supplied retro theme catalog.

Providerno provider required in the harness

A non-shadcn project must add the base Select primitive and its UI dependencies, configure the source path alias, install nuqs, include the registry's global theme styles, and mount its theme provider. It must also supply Next.js navigation support or rewrite the URL synchronization for its router.
