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.

Installation

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

npm i @vueuse/core

npm i @vueuse/core

Add ons | Nuxt Module

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

Demos

CDN 

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

<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.

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

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

Nuxt 3

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

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

Nuxt 2

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

// 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>

<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

import { useLocalStorage, useMouse, usePreferredDark } 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(
      'my-storage',
      {
        name: 'Apple',
        color: 'red',
      },
    )

    return { x, y, isDark, store }
  },
}

import { useLocalStorage, useMouse, usePreferredDark } 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(
      'my-storage',
      {
        name: 'Apple',
        color: 'red',
      },
    )

    return { x, y, isDark, store }
  },
}
