React Native for Web

React Native components and APIs for the Web.

Browser support: Chrome, Firefox, Safari >= 7, IE 10, Edge.

Overview

"React Native for Web" is a project to bring React Native's building blocks and touch handling to the Web.

React Native provides a foundational layer to support interoperable, zero-configuration React component development. This is missing from React's web ecosystem where OSS components rely on inline styles (usually without vendor prefixes), or require build tool configuration. This project allows components built upon React Native to be run on the Web, and it manages all component styling out-of-the-box.

For example, the View component makes it easy to build cross-browser layouts with flexbox, such as stacked and nested boxes with margin and padding. And the StyleSheet API converts styles defined in JavaScript into "Atomic CSS".

Quick start

To install in your app:

npm install --save react react-native-web

Read the Client and Server rendering guide.

You can also bootstrap a standard React Native project structure for web by using react-native-web-starter.

Examples

Demos:

• React Native for Web: Playground.
• TicTacToe
• 2048

Sample:

import React from 'react'
import { AppRegistry, Image, StyleSheet, Text, View } from 'react-native'

// Components
const Card = ({ children }) => <View style={styles.card}>{children}</View>
const Title = ({ children }) => <Text style={styles.title}>{children}</Text>
const Photo = ({ uri }) => <Image source={{ uri }} style={styles.image} />
const App = () => (
  <Card>
    <Title>App Card</Title>
    <Photo uri="/some-photo.jpg" />
  </Card>
)

// Styles
const styles = StyleSheet.create({
  card: {
    flexGrow: 1,
    justifyContent: 'center'
  },
  title: {
    fontSize: '1.25rem',
    fontWeight: 'bold'
  },
  image: {
    height: 40,
    marginVertical: 10,
    width: 40
  }
})

// App registration and rendering
AppRegistry.registerComponent('MyApp', () => App)
AppRegistry.runApplication('MyApp', { rootTag: document.getElementById('react-root') })
