Nuxt UI v4

Component library for Vue 3 and Nuxt 4+ built on Reka UI (headless) + Tailwind CSS v4 + Tailwind Variants.

Current stable version: v4.3.0 (December 2025)

When to Use

• Installing/configuring @nuxt/ui
• Using UI components (Button, Card, Table, Form, etc.)
• Customizing theme (colors, variants, CSS variables)
• Building forms with validation
• Using overlays (Modal, Toast, CommandPalette)
• Working with composables (useToast, useOverlay)

For Vue component patterns: use vue skill For Nuxt routing/server: use nuxt skill
