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'

export default {
  setup() {
    const { pixelRatio } = useDevicePixelRatio()

    return { pixelRatio }
  },
}

Component Usage

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