ShadCN UI is a collection of beautifully designed components built using Tailwind CSS and Radix UI.

<!-- Example: Importing a button from ShadCN UI -->
<script setup>
import { Button } from "@/components/ui/button"; <!-- Importing button component -->
</script>

<template>
  <Button>Click Me</Button> <!-- Using ShadCN button -->
</template>
            

To install ShadCN components, use the CLI to scaffold your preferred component.

<!-- Installation example using CLI -->
npx shadcn-ui@latest init <!-- Initializes ShadCN in your project -->
npx shadcn-ui@latest add button <!-- Adds a button component -->
            

ShadCN UI depends on Tailwind CSS, Radix UI primitives, and class-variance-authority for styling variants.

<!-- Example: Installing dependencies -->
npm install tailwindcss radix-ui react-icons class-variance-authority <!-- Required packages -->
            

You can customize components using Tailwind utility classes or by modifying the exported component files directly.

<!-- Example: Customizing a button -->
export function CustomButton() {
  return (
    <button className="bg-green-500 text-white px-4 py-2 rounded">
      Custom Button
    </button>
  )
}
            

Yes, ShadCN supports dark mode using Tailwind’s dark mode class strategy.

<!-- Example: Dark mode with Tailwind -->
<div className="dark:bg-black dark:text-white p-4">
  This text is styled for dark mode
</div>
            

Yes, ShadCN components work perfectly in Next.js with proper Tailwind and plugin setup.

<!-- Example: Button in Next.js -->
'use client';

import { Button } from "@/components/ui/button";

export default function Home() {
  return (
    <Button>Next.js Button</Button>
  )
}
            

ShadCN integrates well with React Icons or Lucide icons for adding visual elements.

<!-- Example: Using Lucide icon -->
import { Smile } from "lucide-react";

export function IconLabel() {
  return (
    <div className="flex items-center space-x-2">
      <Smile />
      <span>Happy UI</span>
    </div>
  )
}
            

You can animate ShadCN components using libraries like Framer Motion.

<!-- Example: Button with animation -->
import { motion } from "framer-motion";

<motion.button whileHover={{ scale: 1.1 }} className="px-4 py-2 bg-blue-500 text-white">
  Hover Me
</motion.button>
            

Slots allow flexible placement of child elements inside components.

<!-- Example: Passing content to slot -->
<Alert>
  <AlertTitle>Notice</AlertTitle>
  <AlertDescription>This is important!</AlertDescription>
</Alert>

When customizing ShadCN UI components, maintain consistency by using Tailwind CSS utility classes, avoid deep overrides of core styles, leverage component variants, and ensure accessibility compliance.

Optimize performance by leveraging Tailwind's purge CSS to remove unused styles, using dynamic imports for heavy components, memoizing components with React.memo, and avoiding unnecessary re-renders.

ShadCN UI follows WAI-ARIA guidelines for accessibility. To ensure compliance, use semantic HTML, add ARIA attributes where needed, test with screen readers, and validate color contrast ratios.

Implement dark mode by using Tailwind CSS dark variant classes, toggling a dark class on the root element, and ensuring color contrasts and UI components adapt correctly.

State management strategies include React Context for global state, Redux or Zustand for complex state, and React Query for asynchronous data fetching in ShadCN UI projects.

Extend components by wrapping ShadCN UI components in your own with additional props, styles, or behavior, maintaining interface consistency and reusability.

Common pitfalls include conflicting Tailwind configurations, CSS specificity issues, and inconsistent design tokens. Avoid them by auditing Tailwind configs and isolating ShadCN UI styles properly.

Ensure SSR compatibility by avoiding browser-specific APIs in components, using Next.js or Remix frameworks with proper hydration, and lazy-loading client-only components as needed.

Recommended testing includes unit tests with Jest, component snapshot testing with React Testing Library, and end-to-end tests with Cypress focusing on user interactions.

Contribute by submitting issues or pull requests on GitHub, creating component examples, improving documentation, or sharing your own component libraries that extend ShadCN UI.

ShadCN UI components are built with React and designed for seamless integration with Next.js, supporting SSR, dynamic imports, and Tailwind CSS for styling.

It can be used with other libraries, but be cautious of conflicting styles or class names. Use CSS isolation strategies and configure Tailwind to avoid clashes.

ShadCN UI excels in building modern, responsive dashboards, admin panels, landing pages, and applications requiring fast prototyping with consistent styling.

Customize theme tokens by modifying Tailwind CSS configuration files (tailwind.config.js) to override colors, fonts, spacing, and extend variants as needed.

Integrate i18n libraries like react-intl or next-i18next alongside ShadCN UI, keeping text content and labels dynamic while preserving component styling and accessibility.

Utilize Tailwind's responsive utility classes for breakpoints, combine with ShadCN UI’s flexible components, and test layouts across devices to ensure usability.

Use browser dev tools, React DevTools, Tailwind CSS Intellisense, and console logging combined with testing libraries to identify styling or logic issues efficiently.

Keep dependencies updated by regularly reviewing release notes, using semantic versioning, testing updates in staging environments, and employing tools like Renovate or Dependabot.

Ensure input sanitization, avoid injecting unsafe HTML, follow OWASP guidelines, and keep third-party dependencies updated to mitigate vulnerabilities when using ShadCN UI.
