+# useScreenOrientation
+
+Reactive [Screen Orientation API](https://developer.mozilla.org/en-US/docs/Web/API/Screen_Orientation_API). It provides web developers with information about the user's current screen orientation.
+
+## Usage
+
+```ts
+import { useScreenOrientation } from '@vueuse/core'
+
+const {
+  isSupported,
+  orientation,
+  angle,
+  lockOrientation,
+  unlockOrientation,
+} = useScreenOrientation()
+```
+
+To lock the orientation, you can pass an [OrientationLockType](https://developer.mozilla.org/en-US/docs/Web/API/ScreenOrientation/type) to the lockOrientation function:
+
+```ts
+import { useScreenOrientation } from '@vueuse/core'
+
+const {
+  isSupported,
+  orientation,
+  angle,
+  lockOrientation,
+  unlockOrientation,
+} = useScreenOrientation()
+
+lockOrientation('portrait-primary')
+```
+
+and then unlock again, with the following:
+
+```ts
+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"`.

+
+## Type Declarations
+
+```ts
+export type OrientationType =
+  | "portrait-primary"
+  | "portrait-secondary"
+  | "landscape-primary"
+  | "landscape-secondary"
+export type OrientationLockType =
+  | "any"
+  | "natural"
+  | "landscape"
+  | "portrait"
+  | "portrait-primary"
+  | "portrait-secondary"
+  | "landscape-primary"
+  | "landscape-secondary"
+export interface ScreenOrientation extends EventTarget {

+  readonly type: OrientationType
+  readonly angle: number
+  addEventListener: (
+    type: "change",
