jal-co/ui: an open-source React component library that ships components through a shadcn-compatible registry.
Key features:
- 30+ components covering code blocks, GitHub metrics, dev dashboards, and documentation layouts
- Async server components for GitHub stats, npm badge data, and contributor grids fetched at build time via ISR
- shadcn CLI installation: one command downloads the source into your project
- No paywall, no npm package to version-track, no external dependencies as a default
- Pretext-powered layout components that predict text dimensions without DOM measurement
Works with Next.js App Router and Tailwind CSS v4. Every component is editable source in your project. Registry at ui.justinlevine.me.
