[![star this repo](http://githubbadges.com/star.svg?user=react-native-community&repo=react-native-webview&style=flat)](https://github.com/react-native-community/react-native-webview) [![PRs Welcome](https://img.shields.io/badge/PRs-welcome-brightgreen.svg?style=flat-square)](http://makeapullrequest.com) [![All Contributors](https://img.shields.io/badge/all_contributors-12-orange.svg?style=flat-square)](#contributors) [![Known Vulnerabilities](https://snyk.io/test/github/react-native-community/react-native-webview/badge.svg?style=flat-square)](https://snyk.io/test/github/react-native-community/react-native-webview)
**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)).

## Platforms Supported
- [x] iOS (both UIWebView and WKWebView)
- [x] Android
_Note: React Native WebView is not currently supported by Expo unless you "eject"._
## Getting Started
Read our [Getting Started Guide](docs/Getting-Started.md). If any step seems unclear, please create a detailed issue.
## 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:**
- [2.0.0](https://github.com/react-native-community/react-native-webview/releases/tag/v2.0.0) - First release this is a replica of the core webview component
- [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).
- [4.0.0](https://github.com/react-native-community/react-native-webview/releases/tag/v4.0.0) - Added cache (enabled by default).
- [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.
**Upcoming:**
- UIWebView removal
- this.webView.postMessage() removal (never documented and less flexible than injectJavascript)
- Typescript rewrite
- 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
- There's a [problem](https://stackoverflow.com/questions/52872045/rendering-webview-on-android-device-overlaps-previous-siblings-from-same-parent) on some Android devices where the webview could overlap previous siblings from same parent. To fix this, wrap the WebView in a View with style `overflow: hidden`.
