# Nuxt UI v4

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

**Current stable version:** v4.4.0 (January 2026)

## 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

- [ ] [references/components.md](references/components.md) - if browsing component index or finding components by category
- [ ] [references/forms.md](references/forms.md) - if building forms with validation (Zod/Valibot)
- [ ] [references/overlays.md](references/overlays.md) - if using Toast, Modal, Slideover, Drawer, or CommandPalette

| Concept           | Description                                                |
| ----------------- | ---------------------------------------------------------- |
| UApp              | Required wrapper component for Toast, Tooltip, overlays    |
| Tailwind Variants | Type-safe styling with slots, variants, compoundVariants   |
| Semantic Colors   | primary, secondary, success, error, warning, info, neutral |
| Reka UI           | Headless component primitives (accessibility built-in)     |

> For headless component primitives (API details, accessibility patterns, asChild): read the **reka-ui** skill
