useDevicePixelRatio
Reactively track window.devicePixelRatio

window.devicePixelRatiochange. So this function usesTesting 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
<template>
<UseDevicePixelRatio v-slot="{ pixelRatio }">
Pixel Ratio: {{ pixelRatio }}
</UseDevicePixelRatio>
</template>
Type Declarations
export interface UseDevicePixelRatioOptions extends ConfigurableWindow {}
export interface UseDevicePixelRatioReturn {
