Installation

pnpm dlx shadcn@latest add @8bitcn/xp-bar

Requires @8bitcn in the registries of your components.json (shadcn adds official directory namespaces automatically).

Usage

usage.tsx
import XpBar from "@/components/ui/8bit/xp-bar";<XpBar value={65} />
  • Show player XP, completion progress, or other game-like progress toward a 100% goal.
  • Use the retro variant when a segmented, pixel-art appearance fits the interface.
  • Use the default variant for a simpler continuous fill with the same 8-bit frame.
  • Show the level-up message when the value reaches exactly 100.

API reference

PropTypeDefaultDescription
classNamestring—Additional class name applied to the outer wrapper.
variant"retro" | "default"—Selects the fill style. "retro" renders 20 segments; "default" renders a continuous fill.
valuenumber—Progress value. The level-up animation and message appear only when the value is exactly 100.
levelUpMessagestring"LEVEL UP!"Message shown over the bar when value is exactly 100.
propsBitProgressProps—Declared as an optional BitProgressProps object, but the component does not read or spread this nested prop into Progress.
React div attributesReact.ComponentProps<"div">—The component inherits standard div attributes. Apart from className, remaining attributes are spread onto the underlying Progress component rather than the outer wrapper.

Accessibility

  • The underlying Radix Progress root provides progressbar semantics; pass an accessible name, such as aria-label or aria-labelledby, so the progress has a meaningful label.
  • The level-up message is a visual overlay with pointer-events disabled; do not rely on it alone to communicate completion to assistive technology.
  • The blinking message and pulse animation have no reduced-motion handling in this component.
