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.

demo
You may have to use yarn to install the dependencies of the demo and remove demo folder from demo/node_modules/react-native-autoheight-webview, cause of installing a local package with npm will create symlink, but there is no supporting of React Native to symlink (https://github.com/facebook/watchman/issues/105).
