Quick Start (3 Minutes)

For Vue Projects (Vite)

1. Initialize shadcn-vue

npx shadcn-vue@latest init

During initialization:

• Style: New York or Default (cannot change later!)
• Base color: Slate (recommended)
• CSS variables: Yes (required for dark mode)

2. Configure TypeScript Path Aliases

// tsconfig.json
{
  "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

   • Setup commands fail or configuration issues arise
   • Tailwind CSS variables or TypeScript paths broken
   • Trigger phrases: "not working", "error", "fails to", "broken"

2. Load references/components.md when:

   • User asks what components are available (names, categories, status)
   • User needs to add/use a component and wants the correct install/import paths
   • You need to confirm a component exists before recommending a custom build

3. 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"

4. Load references/cli.md when:

   • User asks how to run the CLI (init, add, update) or what prompts mean
   • Need the exact command/flags for installing one or more components
   • Troubleshooting CLI-related issues (registry, paths, overwrites)

5. Load references/dark-mode-setup.md when:

   • Implementing dark mode / theme switching
   • User mentions Vue 3 + Vite, Nuxt, or Astro setup

   • Setting up/adjusting design tokens (colors, radius, typography) for shadcn-vue

7. Load references/mcp.md when:

   • Setting up MCP server for opencode, Codex, Cursor, VS Code
   • Configuring registries in components.json

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

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

---

Common Mistakes

• Running add before init and missing components.json.
• Forgetting to enable the MCP server in the client UI/config.
• Mis-typed registry namespaces (@namespace/component).
• Using CSS variable classes without tailwind.cssVariables: true.

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 npx 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
