vuetify@4.0.1

Material Design component framework for Vue 3. Source citations like lib/framework.js:15 refer to the prepared vuetify@4.0.1 package (package.json:4).

Environment limits

Vue ^3.5.0 peer dependency (package.json:208). No Vue 2 support; Vuetify 2 is EOL (README.md:274).
ESM only: "type": "module" (package.json:32).
Optional peers: vite-plugin-vuetify >=2.1.0, webpack-plugin-vuetify >=3.1.0, typescript >=4.7 (package.json:205).
Modern browsers, Safari 13+ with polyfills, minimum design width 320px (README.md:159).
Default font is Roboto; you must add it yourself, e.g. @fontsource/roboto (https://vuetifyjs.com/getting-started/installation/).

Setup

Vite with automatic treeshaking (preferred). The vuetify plugin must come after the vue plugin:

// vite.config.js
import vue from '@vitejs/plugin-vue'
import vuetify from 'vite-plugin-vuetify'
export default defineConfig({ plugins: [vue(), vuetify()] })

// src/plugins/vuetify.js
import 'vuetify/styles'
import { createVuetify } from 'vuetify'
export default createVuetify({
  // components, directives not needed with the loader plugin
})

Without a loader plugin, register manually; wildcard imports include everything and slow development builds:

import * as components from 'vuetify/components'
import * as directives from 'vuetify/directives'
createVuetify({ components, directives })

createVuetify accepts aliases, blueprint, components, date, defaults, directives, display, goTo, icons, locale, ssr, theme and returns { install, unmount, defaults, display, theme, icons, locale, date, goTo } (lib/framework.js:15). Install with app.use(vuetify); wrap the app in a single <v-app> root.

For SSR frameworks (Nuxt, vite-ssr) set ssr: true so display values render correctly (https://vuetifyjs.com/getting-started/installation/).

Scaffolding: pnpm create vuetify / npm create vuetify@latest (README.md:44).

CDN bundle with everything included: vuetify/dist/vuetify.js (package.json:35).

Components

Prefer imports from vuetify/components/<Group> over vuetify/components (loads only needed styles in dev).
Labs components are NOT production ready; import from vuetify/labs/<Name> or vuetify/labs/components. In 4.0.1 labs holds: VAvatarGroup, VColorInput, VCommandPalette, VDateInput, VFileUpload, VIconBtn, VMaskInput, VPicker, VPie, VStepperVertical, VPullToRefresh, VVideo (lib/labs/components.js:1).
Dynamic <component :is> is invisible to the loader plugin; import those components manually (https://vuetifyjs.com/features/treeshaking/).
Full inventory and export paths: references/exports.md

Configuration

Theme: the v4 default is system (follows prefers-color-scheme), not light (lib/composables/theme.js:10). Pin it with theme: { defaultTheme: 'light' } if system switching is unwanted.
Defaults: set prop defaults per component with createVuetify({ defaults: { VBtn: { ... } } }). class and style work only on component keys, never in the global key (https://vuetifyjs.com/features/global-configuration/).
Display: v4 breakpoints changed; defaults are sm 600, md 840, lg 1145, xl 1545, xxl 2138 (lib/composables/display.js:10).
Icons: default set is mdi and expects the @mdi/font stylesheet, or use mdi-svg for bundled SVG icons (https://vuetifyjs.com/features/icon-fonts/).
Dates: default adapter wraps native Date; swap with any date-io adapter (https://vuetifyjs.com/features/dates/).
Blueprints: createVuetify({ blueprint: md3 }) applies a design-system preset; explicit options override the blueprint (lib/framework.js:15, lib/blueprints/index.js:1).
Details and examples: references/configuration.md

Composables

All exported from the vuetify entry point (lib/composables/index.js:1): useDate, useDefaults, useDisplay, useGoTo, useLayout, useLocale, useRtl, useTheme, useHotkey, useMask.

<script setup>
import { useTheme } from 'vuetify'
const theme = useTheme()
theme.toggle() // light <-> dark
</script>

For hotkeys prefer the cmd modifier (useHotkey('cmd+s', save)); it resolves to Command on Mac and Control elsewhere (lib/composables/hotkey/key-aliases.js:10).

Full API per composable: references/composables.md

Styles

import 'vuetify/styles' is the all-in-one precompiled CSS; modular entries are vuetify/styles/core (must be first), vuetify/styles/colors, vuetify/styles/utilities (package.json:61).
SASS variable overrides require the sass preprocessor and vuetify({ styles: { configFile: 'src/styles/settings.scss' } }) in the loader plugin; use @use 'vuetify/settings' with (...).
v4 styles ship in cascade layers (vuetify-core, vuetify-components, vuetify-overrides, vuetify-utilities, vuetify-final); unlayered user CSS now always wins over Vuetify.

Migrating from v3

v4 is a breaking MD3 release. Highest-impact changes:

Grid uses CSS gap; dense is now density="compact", align/justify/order/align-self props replaced by utility classes. VRow gains a gap prop (lib/components/VGrid/VRow.js:154).
Typography variants renamed: h1-h3 -> display-*, h4-h6 -> headline-*, subtitle-1/body-1 -> body-large, caption -> body-small, button/subtitle-2 -> label-large.
Elevation reduced from levels 0-24 to 0-5 (lib/styles/settings/_elevations.scss:6).
VSelect/VCombobox/VAutocomplete slot item renamed to internalItem; item is now an alias for internalItem.raw.
VForm slot values (isValid, errors, ...) are unwrapped, no longer refs.
Defaults merging skips undefined; use null to override a global default.

Common pitfalls

Missing icon font: components render blank icons until @mdi/font CSS (or an SVG set) is installed.
Missing Roboto font: text renders with fallback font (README.md:159).
Styles broken after adding custom CSS: check layer order; place overrides inside @layer vuetify-overrides or declare your layer order explicitly.
VNumberInput uses toFixed() internally; for arbitrary-precision decimals use v-text-field with decimal.js (lib/components/VNumberInput/VNumberInput.js:81, https://vuetifyjs.com/components/number-inputs/).
Do not use vuetify/styles inside SASS files; it resolves to precompiled CSS. Use vuetify or vuetify/settings (https://vuetifyjs.com/features/sass-variables/).
