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)
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 run react-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.
