Example
React Native for Web exports its components and a reference to the React
installation. Styles are defined with, and used as JavaScript objects.
Component:
import React, { Image, StyleSheet, Text, View } from 'react-native-web'
const Title = ({ children }) => <Text style={styles.title}>{children}</Text>
const Summary = ({ children }) => (
<View style={styles.text}>
<Text style={styles.subtitle}>{children}</Text>
</View>
)
class App extends React.Component {
render() {
return (
<View style={styles.row}>
<Image
source={{ uri: 'http://facebook.github.io/react/img/logo_og.png' }}
style={styles.image}
/>
<Title>React Native Web</Title>
<Summary>Build high quality web apps using React</Summary>
</View>
)
},
})
const styles = StyleSheet.create({
row: {
flexDirection: 'row',
margin: 40
},
image: {
height: 40,
marginRight: 10,
width: 40,
},
text: {
flex: 1,
justifyContent: 'center'
},
title: {
fontSize: '1.25rem',
fontWeight: 'bold'
},
subtitle: {
fontSize: '1rem'
}
})
Pre-render styles on the server:
// server.js
import App from './components/App'
import React, { StyleSheet } from 'react-native-web'
const html = React.renderToString(<App />);
const css = StyleSheet.renderToString();
const Html = () => (
<html>
<head>
<style id="react-stylesheet">{css}</style>
</head>
<body>
<div id="react-root" dangerouslySetInnerHTML={{ __html: html }} />
</body>
</html>
)
Render styles on the client:
// client.js
import App from './components/App'
import React, { StyleSheet } from 'react-native-web'
React.render(
<App />,
document.getElementById('react-root')
)
document.getElementById('stylesheet').textContent = StyleSheet.renderToString()
APIs
StyleSheet
StyleSheet is a style abstraction that transforms inline styles to CSS on the client or the server. It provides a minimal CSS reset.
Components
Image
An accessibile image component with support for image resizing, default image, and child content.
ListView
(TODO)
ScrollView
(TODO)
Text
Displays text as an inline block and supports basic press handling.
TextInput
Accessible single- and multi-line text input via a keyboard.
Touchable
Touch bindings for press and long press.
View
The fundamental UI building block using flexbox for layout.
Styling
React Native for Web relies on styles being defined in JavaScript.
The View component makes it easy to build common layouts with flexbox, such
as stacked and nested boxes with margin and padding. See this guide to
flexbox.
Styling components can be achieved with inline styles or the use of StyleSheet.
