Installation

pnpm dlx shadcn@latest add https://beautiful-ui.dev/r/sparkline.jsonRadix
pnpm dlx shadcn@latest add https://beautiful-ui.dev/r/radix-nova/sparkline.jsonFree, no account or key. Use the command for your project's primitives: a radix-*, new-york or default style in components.json is Radix, a base-* style is Base UI. With the @beautiful-ui registry added, @beautiful-ui/<name> picks for you.
Install by hand
- 1. No extra packages: React and Tailwind CSS v4 are enough.
- 2. Copy the files to these paths (Source below, or save them all as a .zip)
- components/ui/notchset/sparkline.tsx
- lib/beautiful-ui/notchset/instrument.tsx
- lib/beautiful-ui/notchset/root.ts
- lib/beautiful-ui/notchset/chart-geometry.ts
- 3. No stylesheet needed.
- 4. Install what it builds on first: shadcn's cn helper (lib/utils.ts, from npx shadcn init), the theme foundation (its tokens and base styles)
Styles didn't apply?
The CLI adds the styles to the CSS file named in components.json (tailwind.css). Check that it points at your global stylesheet, that the project uses Tailwind CSS v4, and that the file is imported in your root layout. Installed by hand: paste styles.css into that file.
