Get Started

VueUse is a collection of utility functions based on Composition API. We assume you are already familiar with the basic ideas of Composition API before you continue.


🎩 VueUse works for Vue 2 & 3 within a single package by the power of vue-demi!

npm i @vueuse/core

Vue 3 Demo: Vite, Webpack / Vue 2 Demo: Vue CLI

From v6.0, VueUse requires vue >= v3.2 or @vue/composition-api >= v1.1


<script src=""></script>
<script src=""></script>

It will be exposed to global as window.VueUse


From v6.7.0, we shipped a Nuxt module to enable auto importing for Nuxt 3 and Nuxt Bridge.

// nuxt.config.js
export default {
  buildModules: [

And then use VueUse function anywhere in your Nuxt app. For example:

<script setup lang="ts">
const { x, y } = useMouse()

  <div>pos: {{x}}, {{y}}</div>

Usage Example

Simply importing the functions you need from @vueuse/core

import { useMouse, usePreferredDark, useLocalStorage } from '@vueuse/core'

export default {
  setup() {
    // tracks mouse position
    const { x, y } = useMouse()

    // is user prefers dark theme
    const isDark = usePreferredDark()

    // persist state in localStorage
    const store = useLocalStorage(
        name: 'Apple',
        color: 'red',

    return { x, y, isDark, store }
