Measured entry

8bitcn-xp-bar

transition-effectskeuomorphismmotion on file

A pixel-styled experience bar that fills with a transition and flashes a configurable level-up message when complete. It ships as a shadcn registry bundle containing the wrapper, a Radix Progress primitive, and retro CSS, with Tailwind classes, CVA, a shared cn helper, and a Google-hosted font in the dependency chain.

Verdict

A focused, characterful choice for retro dashboards and game interfaces, and it builds and mounts cleanly. Adopt it only after supplying an accessible label and checking narrow layouts; the completion blink should also respect your motion policy.

Use it if

  • You need a game-like progress indicator with an explicit completion celebration.
  • Your interface already uses Tailwind and can accommodate the component's pixel-art styling.
  • You want both a continuous fill and an optional segmented retro variant.

Skip it if

  • You need an accessible progress bar without adding a label yourself, since the supplied component has no accessible name.
  • Your layout must remain overflow-free in narrow containers without adjustment.
  • Your visual system is restrained or corporate and the heavy pixel border and blinking completion message would feel out of place.
  • Your project cannot load a font from Google or bundle a local replacement.

Providerno provider required in the harness

In a non-shadcn project, add Radix Progress, class-variance-authority, clsx, and tailwind-merge; provide the cn utility and matching import aliases; configure Tailwind to scan the component files; and include the retro stylesheet plus either its Google font import or a local font replacement. Add an accessible label when rendering the bar.
