**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)).

> We just swapped out the React Native WebView in our app with the version from React Native Community. The swap took less than a day, required almost no code modifications, and is faster and CSS works better. Props to everyone in the community (including those at Infinite Red) that helped get that component split out.

## Platforms Supported

- [x] iOS (both UIWebView and WKWebView)
- [x] Android

_Note: React Native WebView is not currently supported by Expo unless you "eject"._

## Versioning

If you need the exact same WebView as the one from react-native, please use version **2.0.0**. Future versions will follow [semantic versioning](https://semver.org/).

## Getting Started

```
$ yarn add react-native-webview
$ react-native link react-native-webview
```

Read our [Getting Started Guide](./docs/Getting-Started.md) for more.

## 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://infinite.red/react-native" }}
        style={{ marginTop: 20 }}
      />
    );
  }
}
```

For more, read the [API Reference](./docs/Reference.md) and [Guide](./docs/Guide.md). If you're interested in contributing, check out the [Contributing Guide](./docs/Contributing.md).

## Migrate from React Native core WebView to React Native WebView

Simply install React Native WebView and then use it in place of the core WebView. Their APIs are currently identical, except that this package defaults `useWebKit={true}` unlike the built-in WebView.

## Troubleshooting

- 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`.
