Yeah works nicely on my side! I didn’t do anything to the RN code, and now when I look back, I didn’t do anything special in my webpack.config.js or my babel.config.js, but yeah most importantly I didn’t change the application code.

Here’s my webpack and babel files – something in here made it work but I cant explicitly remember what anymore 😃

I think it could have been using the appropriate resolves and including the react-native-modalize and babel-polyfill module in the compileNodeModules?

const compileNodeModules = ['react-native-modalize', 'babel-polyfill']

resolve: {
    extensions: ['.web.js', '.web.ts', '.web.tsx', '.web.jsx', '.js', '.ios.js', 'native.js', '.jsx', '.ts'],

I actually got it working quite easily - at least it builds ok – haven’t tested the UI just yet. Will post what I did to get it to build at least a bit later today.
