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).

Versioning
This project follows semantic versioning. We do not hesitate to release breaking changes but they will be in a major version.
Breaking History:
- 2.0.0 - First release this is a replica of the core webview component
- 3.0.0 - WKWebview: Add shared process pool so cookies and localStorage are shared across webviews in iOS (enabled by default).
- 4.0.0 - Added cache (enabled by default).
- 5.0.1 - 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:
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 runreact-native link
or there was some error with the linking process - There's a problem 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
.
