Learn VueUse with video

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.

Installation

🎩 From v4.0, it works for Vue 2 & 3 within a single package by the power of vue-demi!

npm i @vueuse/core

Add ons | Nuxt Module

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

Demos

• Vite + Vue 3
• Nuxt 3 + Vue 3
• Webpack + Vue 3
• Nuxt 2 + Vue 2
• Vue CLI + Vue 2

CDN

<script src="https://unpkg.com/@vueuse/shared"></script>

<script src="https://unpkg.com/@vueuse/core"></script>

It will be exposed to global as window.VueUse

Nuxt

From v7.2.0, we shipped a Nuxt module to enable auto importing for Nuxt 3 and Nuxt Bridge.

Install the vueuse module into your application using nuxi:

npx nuxi@latest module add vueuse

Or use npm:

npm i -D @vueuse/nuxt @vueuse/core

Nuxt 3

// nuxt.config.ts
export default defineNuxtConfig({
  modules: [
    '@vueuse/nuxt',
  ],
})

Nuxt 2

// nuxt.config.js
export default {
  buildModules: [
    '@vueuse/nuxt',
  ],
}

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

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

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

Usage Example

Simply importing the functions you need from @vueuse/core

<script setup>
import { useLocalStorage, useMouse, usePreferredDark } from '@vueuse/core'

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

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

// persist state in localStorage
const store = useLocalStorage(
  'my-storage',
  {
    name: 'Apple',
    color: 'red',
  },
)
</script>
