useScreenOrientation

Reactive Screen Orientation API. It provides web developers with information about the user's current screen orientation.

Usage

import { useScreenOrientation } from '@vueuse/core'

const {
  isSupported,
  orientation,
  angle,
  lockOrientation,
  unlockOrientation,
} = useScreenOrientation()

To lock the orientation, you can pass an OrientationLockType to the lockOrientation function:

import { useScreenOrientation } from '@vueuse/core'

const {
  isSupported,
  orientation,
  angle,
  lockOrientation,
  unlockOrientation,
} = useScreenOrientation()

lockOrientation('portrait-primary')

and then unlock again, with the following:

import { useScreenOrientation } from '@vueuse/core'

const { unlockOrientation } = useScreenOrientation()
// ---cut---
unlockOrientation()

Accepted orientation types are one of "landscape-primary", "landscape-secondary", "portrait-primary", "portrait-secondary", "any", "landscape", "natural" and "portrait".
