React Native Hooks

React Native APIs turned into React Hooks allowing you to access asynchronous APIs directly in your functional components.

Note: You must use React Native >= 0.59.0

Installation with npm

npm install @react-native-community/hooks

Installation with yarn

yarn add @react-native-community/hooks

API

`useAccessibilityInfo`

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.

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

const currentAppState = useAppState()

`useBackHandler`

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

useBackHandler(() => {
  if (shouldBeHandledHere) {
    // handle it
    return true
  }
  // let the default thing happen
  return false
})

`useCameraRoll`

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

const [photos, getPhotos, saveToCameraRoll] = useCameraRoll()

{
  photos.map((photo, index) => /* render photos */)
}

<Button title='Get Photos' onPress={() => getPhotos()}>Get Photos</Button>

`useClipboard`

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

const [data, setString] = useClipboard()

<Text>{data}</Text>

<Button title='Update Clipboard' onPress={() => setString('new clipboard data')}>Set Clipboard</Button>

`useDimensions`

Gets dimensions and sets up a listener that will change the dimensions if the user changes device orientation.

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

const dimensions = useDimensions()
// or
const { width, height } = useDimensions().window
// or
const screen = useDimensions().screen

`useImageDimensions`

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`

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

const keyboard = useKeyboard()

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

`useInteractionManager`

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

const interactionReady = useInteractionManager()

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

`useDeviceOrientation`

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

const orientation = useDeviceOrientation()

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

`useLayout`

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

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

console.log('layout: ', layout)

<View onLayout={onLayout} style={{width: 200, height: 200, marginTop: 30}} />
