Use EventListener with ease. Register using addEventListener on mounted, and removeEventListener automatically on unmounted.
Usage
import { useEventListener } from '@vueuse/core'
useEventListener('mousemove', (evt) => { console.log(evt) })
Custom Event Target
useEventListener(document, 'visibilitychange', (evt) => { console.log(evt) })
