**React Native WebView** is a modern, well-supported, and cross-platform WebView for React Native. It is intended to be a replacement for the built-in WebView (which will be [removed from core](https://github.com/react-native-community/discussions-and-proposals/pull/3)).

## Versioning

This project follows [semantic versioning](https://semver.org/). We do not hesitate to release breaking changes but they will be in a major version.

**Breaking History:**

Current Version: ![version](https://img.shields.io/npm/v/react-native-webview.svg)

- [5.0.**1**](https://github.com/react-native-community/react-native-webview/releases/tag/v5.0.0) - Refactored the old postMessage implementation for communication from webview to native.
- [4.0.0](https://github.com/react-native-community/react-native-webview/releases/tag/v4.0.0) - Added cache (enabled by default).
- [3.0.0](https://github.com/react-native-community/react-native-webview/releases/tag/v3.0.0) - WKWebview: Add shared process pool so cookies and localStorage are shared across webviews in iOS (enabled by default).

**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:

```jsx
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/' }} />
    );
  }
}
```

## Common issues

- If you're getting `Invariant Violation: Native component for "RNCWKWebView does not exist"` it likely means you forgot to run `react-native link` or there was some error with the linking process
