react-native-autoheight-webview

An auto height webview for React Native.

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 >= 0.47)

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)
