---name: shadcn-uidescription: Expert guidance for integrating and building applications with shadcn/ui components, including component discovery, installation, customization, and best practices.allowed-tools:  - "shadcn*:*"  - "mcp_shadcn*"  - "Read"  - "Write"  - "Bash"  - "web_fetch"--- # shadcn/ui Component Integration You are a frontend engineer specialized in building applications with shadcn/ui—a collection of beautifully designed, accessible, and customizable components built with Radix UI or Base UI and Tailwind CSS. You help developers discover, integrate, and customize components following best practices. ## Core Principles shadcn/ui is **not a component library**—it's a collection of reusable components that you copy into your project. This gives you:- **Full ownership**: Components live in your codebase, not node_modules- **Complete customization**: Modify styling, behavior, and structure freely, including choosing between Radix UI or Base UI primitives- **No version lock-in**: Update components selectively at your own pace- **Zero runtime overhead**: No library bundle, just the code you need ## Component Discovery and Installation ### 1. Browse Available Components Use the shadcn MCP tools to explore the component catalog and Registry Directory:- **List all components**: Use `list_components` to see the complete catalog- **Get component metadata**: Use `get_component_metadata` to understand props, dependencies, and usage- **View component demos**: Use `get_component_demo` to see implementation examples ### 2. Component Installation There are two approaches to adding components: **A. Direct Installation (Recommended)**```bashnpx shadcn@latest add [component-name]``` This command:- Downloads the component source code (adapting to your config: Radix vs Base UI)- Installs required dependencies- Places files in `components/ui/`- Updates your `components.json` config **B. Manual Integration**1. Use `get_component` to retrieve the source code2. Create the file in `components/ui/[component-name].tsx`3. Install peer dependencies manually4. Adjust imports if needed ### 3. Registry and Custom Registries If working with a custom registry (defined in `components.json`) or exploring the Registry Directory:- Use `get_project_registries` to list available registries- Use `list_items_in_registries` to see registry-specific components- Use `view_items_in_registries` for detailed component information- Use `search_items_in_registries` to find specific components ## Project Setup ### Initial Configuration For **new projects**, use the `create` command to customize everything (style, fonts, component library): ```bashnpx shadcn@latest create``` For **existing projects**, initialize configuration: ```bashnpx shadcn@latest init``` This creates `components.json` with your configuration:- **style**: default, new-york (classic) OR choose new visual styles like Vega, Nova, Maia, Lyra, Mira- **baseColor**: slate, gray, zinc, neutral, stone- **cssVariables**: true/false for CSS variable usage- **tailwind config**: paths to Tailwind files- **aliases**: import path shortcuts- **rsc**: Use React Server Components (yes/no)- **rtl**: Enable RTL support (optional) ### Required Dependencies shadcn/ui components require:- **React** (18+)- **Tailwind CSS** (3.0+)- **Primitives**: Radix UI OR Base UI (depending on your choice)- **class-variance-authority** (for variant styling)- **clsx** and **tailwind-merge** (for class composition) ## Component Architecture ### File Structure```src/├── components/│   ├── ui/              # shadcn components│   │   ├── button.tsx│   │   ├── card.tsx│   │   └── dialog.tsx│   └── [custom]/        # your composed components│       └── user-card.tsx├── lib/│   └── utils.ts         # cn() utility└── app/    └── page.tsx``` ### The `cn()` Utility All shadcn components use the `cn()` helper for class merging: ```typescriptimport { clsx, type ClassValue } from "clsx"import { twMerge } from "tailwind-merge" export function cn(...inputs: ClassValue[]) {  return twMerge(clsx(inputs))}``` This allows you to:- Override default styles without conflicts- Conditionally apply classes- Merge Tailwind classes intelligently ## Customization Best Practices ### 1. Theme Customization Edit your Tailwind config and CSS variables in `app/globals.css`: ```css@layer base {  :root {    --background: 0 0% 100%;    --foreground: 222.2 84% 4.9%;    --primary: 221.2 83.2% 53.3%;    /* ... more variables */  }    .dark {    --background: 222.2 84% 4.9%;    --foreground: 210 40% 98%;    /* ... dark mode overrides */  }}``` ### 2. Component Variants Use `class-variance-authority` (cva) for variant logic: ```typescriptimport { cva } from "class-variance-authority" const buttonVariants = cva(  "inline-flex items-center justify-center rounded-md",  {    variants: {      variant: {        default: "bg-primary text-primary-foreground",        outline: "border border-input",      },      size: {        default: "h-10 px-4 py-2",        sm: "h-9 rounded-md px-3",      },    },    defaultVariants: {      variant: "default",      size: "default",    },  })``` ### 3. Extending Components Create wrapper components in `components/` (not `components/ui/`): ```typescript// components/custom-button.tsximport { Button } from "@/components/ui/button"import { Loader2 } from "lucide-react" export function LoadingButton({   loading,   children,   ...props }: ButtonProps & { loading?: boolean }) {  return (    <Button disabled={loading} {...props}>      {loading && <Loader2 className="mr-2 h-4 w-4 animate-spin" />}      {children}    </Button>  )}``` ## Blocks and Complex Components shadcn/ui provides complete UI blocks (authentication forms, dashboards, etc.): 1. **List available blocks**: Use `list_blocks` with optional category filter2. **Get block source**: Use `get_block` with the block name3. **Install blocks**: Many blocks include multiple component files Blocks are organized by category:- **calendar**: Calendar interfaces- **dashboard**: Dashboard layouts- **login**: Authentication flows- **sidebar**: Navigation sidebars- **products**: E-commerce components ## Accessibility All shadcn/ui components are built on Radix UI primitives, ensuring:- **Keyboard navigation**: Full keyboard support out of the box- **Screen reader support**: Proper ARIA attributes- **Focus management**: Logical focus flow- **Disabled states**: Proper disabled and aria-disabled handling When customizing, maintain accessibility:- Keep ARIA attributes- Preserve keyboard handlers- Test with screen readers- Maintain focus indicators ## Common Patterns ### Form Building```typescriptimport { Button } from "@/components/ui/button"import { Input } from "@/components/ui/input"import { Label } from "@/components/ui/label" // Use with react-hook-form for validationimport { useForm } from "react-hook-form"``` ### Dialog/Modal Patterns```typescriptimport {  Dialog,  DialogContent,  DialogDescription,  DialogHeader,  DialogTitle,  DialogTrigger,} from "@/components/ui/dialog"``` ### Data Display```typescriptimport {  Table,  TableBody,  TableCell,  TableHead,  TableHeader,  TableRow,} from "@/components/ui/table"``` ## Troubleshooting ### Import Errors- Check `components.json` for correct alias configuration- Verify `tsconfig.json` includes the `@` path alias:  ```json  {    "compilerOptions": {      "paths": {        "@/*": ["./src/*"]      }    }  }  ``` ### Style Conflicts- Ensure Tailwind CSS is properly configured- Check that `globals.css` is imported in your root layout- Verify CSS variable names match between components and theme ### Missing Dependencies- Run component installation via CLI to auto-install deps- Manually check `package.json` for required Radix UI packages- Use `get_component_metadata` to see dependency lists ### Version Compatibility- shadcn/ui v4 requires React 18+ and Next.js 13+ (if using Next.js)- Some components require specific Radix UI versions- Check documentation for breaking changes between versions ## Validation and Quality Before committing components:1. **Type check**: Run `tsc --noEmit` to verify TypeScript2. **Lint**: Run your linter to catch style issues3. **Test accessibility**: Use tools like axe DevTools4. **Visual QA**: Test in light and dark modes5. **Responsive check**: Verify behavior at different breakpoints ## Resources Refer to the following resource files for detailed guidance:- `resources/setup-guide.md` - Step-by-step project initialization- `resources/component-catalog.md` - Complete component reference- `resources/customization-guide.md` - Theming and variant patterns- `resources/migration-guide.md` - Upgrading from other UI libraries ## Examples See the `examples/` directory for:- Complete component implementations- Form patterns with validation- Dashboard layouts- Authentication flows- Data table implementations
