Reka UI

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

Current version: v2.11.0 (October 2026)

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

FileTopics
references/components.mdComponent index by category (Form, Date, Overlay, Menu, Data, etc.)
components/*.mdPer-component details (dialog.md, select.md, etc.)

Guides (see reka-ui.com): Styling, Animation, Composition, SSR, Namespaced, Dates, i18n, Controlled State, Inject Context, Virtualization, Migration

Loading Files

Consider loading these reference files based on your task:

  • references/components.md - if browsing component index by category or searching for specific components

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

For styled Nuxt components built on Reka UI: use nuxt-ui skill

Key Concepts

ConceptDescription
asChildRender as child element instead of wrapper, merging props/behavior
Controlled/UncontrolledUse v-model for controlled, default* props for uncontrolled
PartsComponents split into Root, Trigger, Content, Portal, etc.
forceMountKeep element in DOM for animation libraries
VirtualizationOptimize large lists (Combobox, Listbox, Tree) with virtual scrolling
Context InjectionAccess component context from child components

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>
