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

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

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

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

    return { x, y, isDark, state }
  }
})

Refer to functions list or documentations for more details.

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

npm i @vueuse/core # yarn add @vueuse/core

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

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

It will be exposed to global as window.VueUse
