reka-ui

name reka-ui description Use when building with Reka UI (headless Vue components) - provides component API, accessibility patterns, composition (asChild), controlled/uncontrolled state, virtualization, and styling integration. Formerly Radix Vue. license MIT Reka UI Unstyled, accessible Vue 3 component primitives. WAI-ARIA compliant. Previously Radix Vue. Current version: v2.8.0 (January 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 File Topics references/components.md Component index by category (Form, Date, Overlay, Menu, Data, etc.) components/*.md Per-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 Concept Description asChild Render as child element instead of wrapper, merging props/behavior Controlled/Uncontrolled Use v-model for controlled, default* props for uncontrolled Parts Components split into Root, Trigger, Content, Portal, etc. forceMount Keep element in DOM for animation libraries Virtualization Optimize large lists (Combobox, Listbox, Tree) with virtual scrolling Context Injection Access 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> Recent Updates (v2.6.0-v2.8.0) New component : Rating (v2.8.0) ScrollArea : Added "glimpse" scrollbar mode (v2.8.0) PopperContent : Added hideShiftedArrow prop (v2.8.0) TimeField : Added stepSnapping support (v2.8.0) Breaking : weekStartsOn now locale-independent for date components (v2.8.0) Virtualization : estimateSize accepts function for Listbox/Tree (v2.7.0) Composables : useLocale , useDirection exposed (v2.6.0) Select : disableOutsidePointerEvents prop on Content (v2.7.0) Toast : disableSwipe prop (v2.6.0) Resources Reka UI Docs GitHub Nuxt UI (styled Reka components) shadcn-vue (styled Reka components) Token efficiency: ~350 tokens base, components.md index ~100 tokens, per-component ~50-150 tokens
