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

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

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>
