useDevicePixelRatio

Reactively track window.devicePixelRatio

NOTE: there is no event listener for window.devicePixelRatio change. So this function uses Testing media queries programmatically (window.matchMedia) applying the same mechanism as described in this example.

Usage

import { useDevicePixelRatio } from '@vueuse/core'

const { pixelRatio } = useDevicePixelRatio()

Component Usage

vue

<template>
  <UseDevicePixelRatio v-slot="{ pixelRatio }">
    Pixel Ratio: {{ pixelRatio }}
  </UseDevicePixelRatio>
</template>
