What is react-native-web?
The react-native-web package allows you to use React Native components and APIs to build web applications. It provides a way to write a single codebase that can run on both mobile and web platforms, leveraging the same React Native components.
What are react-native-web's main functionalities?
Cross-Platform Components
This feature allows you to use React Native components like View and Text to build web applications. The code sample demonstrates a simple app that displays 'Hello, world!' using React Native components.
import { View, Text } from 'react-native';
import { AppRegistry } from 'react-native-web';
const App = () => (
<View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
<Text>Hello, world!</Text>
</View>
);
AppRegistry.registerComponent('App', () => App);
AppRegistry.runApplication('App', { initialProps: {}, rootTag: document.getElementById('app') });
StyleSheet for Web
This feature allows you to use the StyleSheet API from React Native to style your web components. The code sample shows how to create and apply styles using StyleSheet.
import { StyleSheet, View, Text } from 'react-native';
import { AppRegistry } from 'react-native-web';
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
},
});
const App = () => (
<View style={styles.container}>
<Text style={styles.welcome}>Welcome to React Native Web!</Text>
</View>
);
AppRegistry.registerComponent('App', () => App);
AppRegistry.runApplication('App', { initialProps: {}, rootTag: document.getElementById('app') });
Event Handling
This feature allows you to handle events such as button presses using React Native's event handling system. The code sample demonstrates a button that shows an alert when pressed.
import { View, Button, Alert } from 'react-native';
import { AppRegistry } from 'react-native-web';
const App = () => (
<View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
<Button
title="Press me"
onPress={() => Alert.alert('Button pressed!')}
/>
</View>
);
AppRegistry.registerComponent('App', () => App);
AppRegistry.runApplication('App', { initialProps: {}, rootTag: document.getElementById('app') });
Other packages similar to react-native-web
react-native-dom
react-native-dom is another package that aims to bring React Native to the web. It provides a similar set of components and APIs as react-native-web but focuses more on integrating with the DOM directly. It is less mature and has a smaller community compared to react-native-web.
react-primitives
react-primitives is a package that provides a set of primitive components that work across multiple platforms, including web, iOS, and Android. It is more lightweight compared to react-native-web and focuses on providing a minimal set of components for cross-platform development.
reactxp
reactxp (React Cross-Platform) is a library developed by Microsoft that allows you to build cross-platform apps using React and React Native. It provides a unified API for building apps that run on web, iOS, Android, and Windows. It is more opinionated and comes with its own set of components and APIs.
