8bitcn-spinner

loaderskeuomorphismmotion on file

A React loading indicator rendered as SVG, with classic ring and diamond pixel variants. It ships as a shadcn registry component and relies on Tailwind utility classes plus a local cn helper backed by clsx and tailwind-merge; it needs no provider.

Verdict

A focused retro spinner with useful classic and diamond treatments and sensible status semantics. It builds and mounts in the prepared harness, but bare mounting did not succeed, so it needs a shadcn-style setup or equivalent project wiring.

Use it if

  • You need a loading indicator that fits a pixel-art or retro interface.
  • Your React app already uses Tailwind and a shadcn-style cn utility.
  • You want a status-labeled SVG whose color and size follow utility classes.

Skip it if

  • Your product uses a polished or neutral visual language where pixel styling would feel out of place.
  • You need motion that automatically respects reduced-motion preferences.
  • You want a dependency-free spinner for a project without Tailwind or shadcn conventions.

Providerno provider required in the harness

In a non-shadcn project, add Tailwind with animation and sizing utilities, configure the at-sign import alias or replace it with a relative path, and provide a cn helper using clsx and tailwind-merge. Add reduced-motion handling if your accessibility policy requires it.
