Package Exports

rn-responsive-styles
rn-responsive-styles/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (rn-responsive-styles) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

React Native Responsive Styles

rn-responsive-styles
Create responsive styles for react-native and react-native-web with minimal rerenders

This library adds support for dynamic styling based on device size, it was built to replace inline dynamic styles for individual components.

This library builds a single stylesheet from the provided styles and conditionally returns them based on device size. It uses a custom version of React Native's useWindowDimensions so that it only re-renders when the device size passes over one of the breakpoints, instead of re-rendering on every pixel change.

Installation

yarn add rn-responsive-styles or npm install rn-responsive-styles --save

Usage

import { Text, View } from 'react-native'
import { CreateResponsiveStyle, DEVICE_SIZES } from 'rn-responsive-styles'

export default function App() {
  const { styles, deviceSize } = useStyles()

  return (
    <View style={styles('container')}>
      <Text style={styles('text')}>Device Size: {deviceSize}</Text>
    </View>
  )
}

const useStyles = CreateResponsiveStyle(
  {
    container: {
      flex: 1,
      backgroundColor: '#fff',
      alignItems: 'center',
      justifyContent: 'center',
    },
    text: {
      fontSize: 30,
      color: 'white',
    },
  },
  {
    [DEVICE_SIZES.EXTRA_LARGE_DEVICE]: {
      container: {
        backgroundColor: 'blue',
      },
    },
    [DEVICE_SIZES.SMALL_DEVICE]: {
      container: {
        backgroundColor: 'red',
      },
      text: {
        fontSize: 20,
      },
    },
  },
)

Options

The currently configured breakpoints are:

Size	Value	Breakpoints
small	`DEVICE_SIZES.SMALL_DEVICE`	`width <= 768`
medium	`DEVICE_SIZES.MEDIUM_DEVICE`	`768 < width <= 992`
large	`DEVICE_SIZES.LARGE_DEVICE`	`992 < width <= 1200`
extra large	`DEVICE_SIZES.EXTRA_LARGE_DEVICE`	`1200 < width`

Right now there is no way to customize the breakpoint values, but I plan on adding that in the future.
