npm install @react-native-community/hooks

```

Installation with yarn

```sh

yarn add @react-native-community/hooks

```

- [useAccessibilityInfo](https://github.com/react-native-community/hooks#useaccessibilityinfo)

- [useAppState](https://github.com/react-native-community/hooks#useappstate)

- [useBackHandler](https://github.com/react-native-community/hooks#usebackhandler)

- [useImageDimensions](https://github.com/react-native-community/hooks#useImageDimensions)

- [useKeyboard](https://github.com/react-native-community/hooks#usekeyboard)

- [useInteractionManager](https://github.com/react-native-community/hooks#useinteractionmanager)

- [useDeviceOrientation](https://github.com/react-native-community/hooks#usedeviceorientation)

- [useLayout](https://github.com/react-native-community/hooks#uselayout)

- [useRefresh](https://github.com/react-native-community/hooks#useRefresh)

### `useAccessibilityInfo`

```js

import {useAccessibilityInfo} from '@react-native-community/hooks'

const {

  boldTextEnabled,

  screenReaderEnabled,

  reduceMotionEnabled, // requires RN60 or newer

  grayscaleEnabled, // requires RN60 or newer

  invertColorsEnabled, // requires RN60 or newer

  reduceTransparencyEnabled, // requires RN60 or newer

} = useAccessibilityInfo()

```

### `useAppState`

AppState will change between one of 'active', 'background', or (iOS) 'inactive' when the app is closed or put into the background.

```js

import {useAppState} from '@react-native-community/hooks'

const currentAppState = useAppState()

```

### `useBackHandler`

```js

import {useBackHandler} from '@react-native-community/hooks'

useBackHandler(() => {

  if (shouldBeHandledHere) {

    // handle it

    return true

  }

  // let the default thing happen

  return false

})

```

### `useImageDimensions`

```js

import {useImageDimensions} from '@react-native-community/hooks'

const source = require('./assets/yourImage.png')

// or

const source = {uri: 'https://your.image.URI'}

const {dimensions, loading, error} = useImageDimensions(source)

if (loading || error || !dimensions) {

  return null

}

const {width, height, aspectRatio} = dimensions

```

### `useKeyboard`

```js

import {useKeyboard} from '@react-native-community/hooks'

const keyboard = useKeyboard()

console.log('keyboard isKeyboardShow: ', keyboard.keyboardShown)

console.log('keyboard keyboardHeight: ', keyboard.keyboardHeight)

```

### `useInteractionManager`

```js

import {useInteractionManager} from '@react-native-community/hooks'

const interactionReady = useInteractionManager()

console.log('interaction ready: ', interactionReady)

```

### `useDeviceOrientation`

```js

import {useDeviceOrientation} from '@react-native-community/hooks'

const orientation = useDeviceOrientation()

console.log('orientation is:', orientation)

```

### `useLayout`

```js

import { useLayout } from '@react-native-community/hooks'

const { onLayout, ...layout } = useLayout()

console.log('layout: ', layout)

```

### `useRefresh`

```js

import { useRefresh } from '@react-native-community/hooks'

const fetch = () => {

    return new Promise((resolve) => setTimeout(resolve, 500))

}

const { isRefreshing, onRefresh } = useRefresh(fetch);

  }

/>
