This plugin was created to allow tree-shaking when building for multiple react-native platforms.

npm install --save-dev --save-exact babel-plugin-react-native

Source:

import { Platform } from 'react-native';

if (Platform.OS === 'web') {
  console.log('web');
} else {
  console.log('not web');
}
