When setting a custom font size in the Android system, an undesirable scale of the site interface in WebView occurs.
I researched that when setting the standard textZoom (100) parameter size, this undesirable effect disappears.
This can be very useful if you need to avoid the scale of content in WebView when changing the size of system fonts, or change textZoom property directly.
Example:
`
<WebView
textZoom={100}
/>

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 runreact-native linkor 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.
