Vuetify0

Headless Vue 3 primitives. Logic only, zero styling. Feeds Vuetify 4 through minor releases.

36 components, 63 composables across selection, forms, data, disclosure, observers, and plugins. Compound-component APIs with WAI-ARIA semantics.

Install

pnpm install @vuetify/v0

No global plugin required. Tree-shakeable imports:

import { createSelection, useBreakpoints } from '@vuetify/v0'
import { Tabs, Dialog } from '@vuetify/v0/components'

Decision table — reach for these first

Check this table before writing custom logic. Match by problem, not by keyword.

Full API and type signatures: see references/REFERENCE.md.

Compound-component pattern

All components are headless and compound. Root owns state, children are named sub-components.

<script setup lang="ts">
  import { Tabs } from '@vuetify/v0/components'
  import { shallowRef } from 'vue'

  const active = shallowRef('overview')
</script>

<template>
  <Tabs.Root v-model="active">
    <Tabs.List>
      <Tabs.Item value="overview">Overview</Tabs.Item>
      <Tabs.Item value="details">Details</Tabs.Item>
    </Tabs.List>
    <Tabs.Panel value="overview">Overview content</Tabs.Panel>
    <Tabs.Panel value="details">Details content</Tabs.Panel>
  </Tabs.Root>
</template>

Available components:

• Primitives: Atom, Portal, Presence
• Providers: Group, Locale, Scrim, Selection, Single, Step, Theme
• Actions: Button, Toggle
• Forms: Checkbox, Combobox, Form, Input, NumberField, Radio, Rating, Select, Slider, Switch
• Disclosure: AlertDialog, Collapsible, Dialog, ExpansionPanel, Popover, Tabs, Treeview
• Semantic: Avatar, Breadcrumbs, Carousel, Pagination, Snackbar, Splitter

More compound examples: see references/component-examples.md.

Must-read rules

1. Check utilities before writing helpers

Import from #v0/utilities (internal) or @vuetify/v0 (external):

• Type guards: isFunction, isString, isNumber, isBoolean, isObject, isArray, isNull, isUndefined, isNullOrUndefined, isPrimitive, isSymbol, isNaN, isElement
• Data: mergeDeep, clamp, range, useId

2. Check globals before SSR branches

Import from #v0/constants/globals:

• IN_BROWSER — replaces typeof window !== 'undefined'
• SUPPORTS_TOUCH, SUPPORTS_MATCH_MEDIA, SUPPORTS_OBSERVER, SUPPORTS_INTERSECTION_OBSERVER, SUPPORTS_MUTATION_OBSERVER

3. Reactivity defaults

• shallowRef for primitives
• ref for objects/arrays
• toRef for derived values (default)
• computed only when caching expensive work

4. Compound components only

Sub-components talk to the root via createContext. Never prop-drill state between siblings. Never build a monolithic component when the root + sub-component pattern fits.

Detailed anti-patterns: see references/anti-patterns.md.

Paper and Vuetify relationship

• @vuetify/v0 — headless (this skill)
• @vuetify/paper — styling primitives that depend on v0
• vuetify v4 — Material Design framework, integrates v0 via minor releases

When the user asks to "style" a v0 component or build a design system, point them at @vuetify/paper or a Paper-based design system (e.g., Emerald, Codex). Keep v0 itself headless.
