Reka UI

Reka UI

Unstyled, accessible Vue 3 component primitives. WAI-ARIA compliant. Previously Radix Vue.

Current version: v2.7.0 (December 2025)

When to Use

• Building headless/unstyled components from scratch
• Need WAI-ARIA compliant components
• Using Nuxt UI, shadcn-vue, or other Reka-based libraries
• Implementing accessible forms, dialogs, menus, popovers

For Vue patterns: use vue skill

Available Guidance

New guides (see reka-ui.com): Controlled State, Inject Context, Virtualization, Migration

Usage Pattern

Load based on context:

• Component index → references/components.md
• Specific component → components/dialog.md, components/select.md, etc.
• For styled Nuxt components built on Reka UI → use nuxt-ui skill

Key Concepts

Installation

// nuxt.config.ts (auto-imports all components)
export default defineNuxtConfig({
  modules: ['reka-ui/nuxt']
})

import { RekaResolver } from 'reka-ui/resolver'
// vite.config.ts (with auto-import resolver)
import Components from 'unplugin-vue-components/vite'

export default defineConfig({
  plugins: [vue(), Components({ resolvers: [RekaResolver()] })]
})

Basic Patterns

<!-- Dialog with controlled state -->
<script setup>
  import {
    DialogRoot,
    DialogTrigger,
    DialogPortal,
    DialogOverlay,
    DialogContent,
    DialogTitle,
    DialogDescription,
    DialogClose
  } from 'reka-ui'
  const open = ref(false)
</script>

<template>
  <DialogRoot v-model:open="open">
    <DialogTrigger>Open</DialogTrigger>
    <DialogPortal>
      <DialogOverlay class="fixed inset-0 bg-black/50" />
      <DialogContent
        class="fixed left-1/2 top-1/2 -translate-x-1/2 -translate-y-1/2 bg-white p-6 rounded"
      >
        <DialogTitle>Title</DialogTitle>
        <DialogDescription>Description</DialogDescription>
        <DialogClose>Close</DialogClose>
      </DialogContent>
    </DialogPortal>
  </DialogRoot>
</template>

<!-- Select with uncontrolled default -->
<SelectRoot default-value="apple">
  <SelectTrigger>
    <SelectValue placeholder="Pick fruit" />
  </SelectTrigger>
  <SelectPortal>
    <SelectContent>
      <SelectViewport>
        <SelectItem value="apple"><SelectItemText>Apple</SelectItemText></SelectItem>
        <SelectItem value="banana"><SelectItemText>Banana</SelectItemText></SelectItem>
      </SelectViewport>
    </SelectContent>
  </SelectPortal>
</SelectRoot>

<!-- asChild for custom trigger element -->
<DialogTrigger as-child>
  <button class="my-custom-button">Open</button>
</DialogTrigger>
