Versioning

This project follows semantic versioning. We do not hesitate to release breaking changes but they will be in a major version.

Breaking History:

Current Version:

• 5.0.1 - Refactored the old postMessage implementation for communication from webview to native.
• 4.0.0 - Added cache (enabled by default).
• 3.0.0 - WKWebview: Add shared process pool so cookies and localStorage are shared across webviews in iOS (enabled by default).
• 2.0.0 - First release this is a replica of the core webview component

Upcoming:

• UIWebView removal
• this.webView.postMessage() removal (never documented and less flexible than injectJavascript)
• Kotlin rewrite
• Maybe Swift rewrite

Usage

Import the WebView component from react-native-webview and use it like so:

import React, { Component } from 'react';
import { StyleSheet, Text, View } from 'react-native';
import { WebView } from 'react-native-webview';

// ...
class MyWebComponent extends Component {
  render() {
    return (
      <WebView source={{ uri: 'https://facebook.github.io/react-native/' }} />
    );
  }
}
