# react-native-autoheight-webview An auto height webview for React Native, or even auto width for inline html. The Current version do not support Android API version 18 and below and the native module has been removed. Cause of javascript execution in webview is not working for Android API version 21 and below (https://github.com/facebook/react-native/issues/14754#issuecomment-361841219), auto width for inline html will not work on Android with API version 22 and below. Cause of changes to lifecycle methods in React 16.3.0 (https://reactjs.org/blog/2018/03/27/update-on-async-rendering.html), please install react-native-autoheight-webview 0.6.1 for the project with 0.47 <= rn < 0.55 Cause of removing unused createJSModules calls in React Naitve 0.47 (https://github.com/facebook/react-native/releases/tag/v0.47.2), please install react-native-autoheight-webview 0.3.1 for the project with 0.44 <= rn < 0.47. Cause of moving View.propTypes to ViewPropTypes in React Naitve 0.44 (https://github.com/facebook/react-native/releases/tag/v0.44.3) and PropTypes has been moved to a separate package in React 16 (https://facebook.github.io/react/blog/2017/04/07/react-v15.5.0.html#migrating-from-react.proptypes), please install react-native-autoheight-webview 0.2.3 for the project with rn < 0.44. `npm install react-native-autoheight-webview --save` (rn >= 0.56) `npm install react-native-autoheight-webview@0.6.1 --save` (0.47 <= rn < 0.56) `npm install react-native-autoheight-webview@0.3.1 --save` (0.44 <= rn < 0.47) `npm install react-native-autoheight-webview@0.2.3 --save` (rn < 0.44) ## Android `react-native link react-native-autoheight-webview` (version 0.10.6 and below) `import AutoHeightWebView from 'react-native-autoheight-webview';` ## iOS `import AutoHeightWebView from 'react-native-autoheight-webview';` ## showcase ![react-native-autoheight-webview iOS](https://media.giphy.com/media/eehXhFjneVqEUCzYip/giphy.gif) ![react-native-autoheight-webview Android](https://media.giphy.com/media/1yTcqipIfHbgNNfcEU/giphy.gif) ## usage ```javascript customStyle={` * { font-family: 'Times New Roman'; } p { font-size: 16px; } `} // animation enabled by default enableAnimation={false}, // only works on enable animation animationDuration={255}, // offset of rn webview margin heightOffset={5} onMessage={e => console.log(e)}, // either height or width updated will trigger this // no support auto width and height will triggered by source changing only on android 5.1 or below version onSizeUpdated={({size => console.log(size.height)})}, // 'file:///android_asset/web/' by default on android, // web/' by default on iOS baseUrl: 'webAssets/', /* use local or remote files to add local files: add baseUrl/files... to android/app/src/assets/ on android add baseUrl/files... to project root on iOS */ files={[{ href: 'cssfileaddress', type: 'text/css', rel: 'stylesheet' }]} // if set to true may cause some layout issues (smaller font size) on iOS // if set to false may cause some layout issues (width of container will be than width of screen) on android scalesPageToFit={Platform.OS === 'Android' ? true : false} // or uri source={{ html: `

Tags are great for describing the essence of your story in a single word or phrase, but stories are rarely about a single thing. If I pen a story about moving across the country to start a new job in a car with my husband, two cats, a dog, and a tarantula, I wouldn’t only tag the piece with “moving”. I’d also use the tags “pets”, “marriage”, “career change”, and “travel tips”.
