Dependencies: Tailwind CSS, Reka UI, Vue 3+ or Nuxt 3+

Quick Start (3 Minutes)

For Vue Projects (Vite)

1. Initialize shadcn-vue

# Using Bun (recommended)
bunx shadcn-vue@latest init

# Using npm
npx shadcn-vue@latest init

During initialization:

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

3. Configure Vite

// vite.config.ts
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import tailwindcss from '@tailwindcss/vite' // Tailwind v4
import path from 'path'

export default defineConfig({
  plugins: [vue(), tailwindcss()],
  resolve: {
    alias: {
      '@': path.resolve(__dirname, './src')
    }
  }
})

4. Add Your First Component

bunx shadcn-vue@latest add button
# or: npx shadcn-vue@latest add button

See Full Setup: templates/quick-setup.ts

For Nuxt Projects

# Create project with Tailwind
bun create nuxt-app my-app
cd my-app
bun add -D @nuxtjs/tailwindcss

bun add zod
# or: npm install zod

Basic Usage

<script setup lang="ts">

})

function onSubmit(values: z.infer<typeof schema>) {
  console.log('Form submitted:', values)
}
</script>

<template>

]
</script>

<template>
  <DataTable :columns="columns" :data="data" />
</template>

Features: Sorting, filtering, pagination, row selection, column visibility, expandable rows

Dark Mode Implementation

Installation

bun add @vueuse/core
# or: npm install @vueuse/core

Setup Theme Provider

<!-- components/ThemeProvider.vue -->
<script setup lang="ts">
import { useColorMode } from '@vueuse/core'

const mode = useColorMode()
</script>

<template>
  <div :class="mode">
    <slot />
  </div>
</template>

Use in Components

<script setup>
import { useColorMode } from '@vueuse/core'

const mode = useColorMode()

function toggleTheme() {
  mode.value = mode.value === 'dark' ? 'light' : 'dark'
}
</script>

<template>
  <Button @click="toggleTheme">
    {{ mode === 'dark' ? '🌙' : '☀️' }}
  </Button>
</template>

Critical Rules

Always Do

✅ Run init before adding components

• Creates required configuration and utilities
• Sets up path aliases

✅ Use CSS variables for theming (cssVariables: true)

• Enables dark mode support
• Flexible theme customization

✅ Configure TypeScript path aliases

• Required for component imports
• Must match components.json aliases

✅ Keep components.json in version control

• Team members need same configuration
• Documents project setup

✅ Use Bun for faster installs (recommended)

• 10-20x faster than npm

Never Do

❌ Don't change style after initialization

• Requires complete reinstall
• Reinitialize in new directory instead

❌ Don't mix Radix Vue and Reka UI v2

• Incompatible component APIs
• Use one or the other

❌ Don't skip TypeScript configuration

• Component imports will fail
• IDE autocomplete won't work

❌ Don't use without Tailwind CSS

• Components are styled with Tailwind
• Won't render correctly

Top 7 Critical Issues

Issue #1: Missing TypeScript Path Aliases

Error: Cannot find module '@/components/ui/button'

Solution:

// tsconfig.json
{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "@/*": ["./src/*"]
    }
  }
}

Issue #2: Tailwind CSS Not Configured

Error: Components render without styles

Solution:

/* src/assets/index.css */
@import "tailwindcss";

// vite.config.ts (Tailwind v4)
import tailwindcss from '@tailwindcss/vite'

export default defineConfig({
  plugins: [vue(), tailwindcss()]
})

Issue #3: CSS Variables Not Defined

Error: Theme colors not applying, gray/transparent components

Solution: Ensure all CSS variables are defined (run init command)

Issue #4: Wrong Style Selected

Error: Components look different than expected

Solution: Choose carefully during init (New York or Default) - cannot change later without reinstall

Issue #5: Mixing Radix Vue and Reka UI

Error: Type conflicts, duplicate components

Solution:

• Use bunx shadcn-vue@latest for Reka UI v2
• Use bunx shadcn-vue@radix for legacy Radix Vue
• Don't mix both

Issue #6: Monorepo Path Issues

Error: Components installed in wrong directory

Solution: Use -c flag to specify workspace:

bunx shadcn-vue@latest init -c ./apps/web
bunx shadcn-vue@latest add button -c ./apps/web

Issue #7: Component Import Fails After Manual Edit

Error: Import paths broken after editing components.json

Solution: Keep components.json and tsconfig.json aliases in sync. Test imports after any config changes.

Reka UI v2 Migration

shadcn-vue now uses Reka UI v2 (formerly Radix Vue) as its foundation. All new components use Reka UI primitives.

Migration: Existing projects should update to Reka UI v2. See official migration guide: shadcn-vue.com/docs/changelog#reka-ui

Configuration

shadcn-vue uses components.json to configure:

• Component paths (@/components/ui)
• Utils location (@/lib/utils)
• Tailwind config paths
• TypeScript paths

Full example: See templates/components.json or generate via bunx shadcn-vue@latest init

Utils Library

The @/lib/utils.ts file provides the cn() helper for merging Tailwind classes:

• Combines multiple className strings
• Uses clsx + tailwind-merge for conflict resolution

Auto-generated by shadcn-vue init - no manual setup needed.

When to Load References

Load these references based on the task:

• Load references/error-catalog.md when:
• User encounters "component not found" or import errors
• Setup commands fail or configuration issues arise
• Tailwind CSS variables or TypeScript paths broken
• Trigger phrases: "not working", "error", "fails to", "broken"

• Load references/component-examples.md when:
• User asks "how do I implement [component]?"
• Need copy-paste examples for specific components
• Building forms, tables, navigation, or data display
• Trigger phrases: "example", "how to use", "implement", "code sample"

• Load references/dark-mode-setup.md when:
• Implementing dark mode / theme switching
• User mentions Vue 3 + Vite, Nuxt, or Astro setup
• Need composable patterns for theme management
• Trigger phrases: "dark mode", "theme", "light/dark", "color scheme"

Integration with Other Skills

This skill composes well with:

• nuxt-v4 → Nuxt framework
• tailwind-v4-shadcn → Tailwind v4 with React shadcn/ui
• react-hook-form-zod → Form validation patterns (similar to Auto Form)
• tanstack-query → Data fetching for tables
• zustand-state-management → State management

Secure Installation

When installing packages during setup, follow supply chain security best practices:

• Block post-install scripts — npm config set ignore-scripts true (or Bun: disabled by default)
• Cooldown period — Wait 7 days for new package versions to be vetted by the community
• Audit before installing — Run socket package score npm <pkg> or use socket npm install <pkg> to check packages

Load the dependency-upgrade skill for full security configuration including Socket CLI integration, cooldown setup, lockfile validation, and CI enforcement.
