A shadcn-compatible UI library for Astro, React and native Shopify Liquid.

• Vanilla Astro Components — No framework dependencies, pure Astro components
• shadcn Compatible — Uses the shadcn CLI and registry system for easy installation
• Content-First — Built for content-driven websites with components like sections, typography and prices
• 100+ Components & Blocks — Ready-to-use UI components and pre-built page blocks
• Tailwind CSS v4 — Styled with the latest Tailwind CSS
• TypeScript — Full TypeScript support
• React extension: the Fulldev extras and blocks for official shadcn/ui React projects; see react/README.md

Install into a Shopify theme with npx shadcn@latest add https://ui.full.dev/r/liquid/components.json, then render ui once in the layout head. Readable CSS, native ES modules and shared tokens, with no theme build step. See Liquid and liquid/README.md.

• Node.js 22.12.0+

1. Create a new Astro project (skip if you have one):

npx create-astro@latest my-project --template with-tailwindcss --install --git
cd my-project

2. Configure TypeScript paths in tsconfig.json:

{
  "compilerOptions": {
    "paths": {
      "@/*": ["./src/*"]
    }
  }
}

3. Initialize Fulldev UI with the shadcn CLI. This writes components.json with the @fulldev registry, adds the theme tokens to your stylesheet, and installs the class helper:

npx shadcn@latest init https://ui.full.dev/r/styles/base-vega/base.json

Replace base-vega with another shadcn/ui style, such as base-nova. To use a shadcn/ui preset, see Presets.

4. Use a container-aware app shell because Fulldev UI uses Tailwind v4 container-query variants like @2xl: and @max-5xl::

---
import "@/styles/global.css"
---

<body class="@container">
  <slot />
</body>

5. Add components:

npx shadcn@latest add @fulldev/button

Visit ui.full.dev for complete documentation, component examples, and usage guides.

For coding agents, install the shadcn skill and the Fulldev UI skill:

npx skills add shadcn/ui
npx skills add fulldotdev/ui --skill fulldev-ui

The fulldev-ui package holds the registry of each release, with no code to import and no dependencies: public/r has the files served at https://ui.full.dev/r, and liquid/ the native Liquid files at their theme paths. Install components with the shadcn CLI as above; the package keeps every release available as a versioned copy.

Requires Node 24 (.node-version), pnpm 12 and Vite+ (vp), which runs the scripts locally and in CI. Installs never run dependency or project lifecycle scripts (pnpm-workspace.yaml).

pnpm install         # frozen lockfile in CI and on Netlify
pnpm dev             # docs site at http://127.0.0.1:4321
vp run build         # builds the docs and the React previews
vp run check  # the source checks every Ready PR runs
vp run test:unit     # the tests in tests, which Ready PRs also run
vp run fix    # Prettier and ESLint fixes
pnpm images          # converts source photos in src to WebP
pnpm ui:add @shadcn/card  # installs with the shadcn CLI, then runs Prettier
pnpm registry:build  # regenerates public/r after registry changes

vp run check runs Prettier, TypeScript and astro check, ESLint, knip, the source photo check, and, specific to this registry, registry:check (the committed public/r must match a fresh build). vp run test:unit runs the tests in tests.

vp run og regenerates the per-page Open Graph screenshots in public/og/. Run it after changing a page's opening content and commit the JPEGs. It uses Playwright's Chromium; CHROME can point to an existing test-browser executable and OG_PORT sets its local preview port. The normal build checks image coverage and dimensions without launching a browser. See DESIGN.md for the screenshot treatment.

pnpm ui:add formats the project right after the install, so a later vp run fix or vp run check does not change the installed components. A plain pnpm dlx shadcn@latest add leaves the CLI's own formatting, which the next format run may change.
