useDevicePixelRatio
Reactively track window.devicePixelRatio
NOTE: there is no event listener for
window.devicePixelRatiochange. So this function usesTesting media queries programmatically (window.matchMedia)as described in this example, but unlike the example this function subscribes to several pixelRatio scales (taken from mydevice.io) to detect anywindow.devicePixelRatiochange.
Demo
Usage
import { useDevicePixelRatio } from '@vueuse/core'
export default {
setup() {
const { pixelRatio } = useDevicePixelRatio()
return { pixelRatio }
},
}
import { useDevicePixelRatio } from '@vueuse/core'
export default {
setup() {
const { pixelRatio } = useDevicePixelRatio()
return { pixelRatio }
},
}
Component
This function also provides a renderless component version via the@vueuse/components package. Learn more about the usage. <UseDevicePixelRatio v-slot="{ pixelRatio }">
Pixel Ratio: {{ pixelRatio }}
</UseDevicePixelRatio>
<UseDevicePixelRatio v-slot="{ pixelRatio }">
