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

Loading Files

Consider loading these reference files based on your task:

• references/installation.md - if installing or configuring @nuxt/ui
• references/theming.md - if customizing theme, colors, or Tailwind Variants
• references/components.md - if browsing component index or finding components by category
• references/forms.md - if building forms with validation (Zod/Valibot)
• references/overlays.md - if using Toast, Modal, Slideover, Drawer, or CommandPalette
• references/composables.md - if using useToast, useOverlay, or other composables

DO NOT load all files at once. Load only what's relevant to your current task.

Key Concepts

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
