Can't get babel-polyfill working with this about webpack-library-starter

Hm ... why you need to add babel-polyfill to the webpack.config.js file. By importing it you are already including it in the bundle.

@krasimir Because of this documentation: https://babeljs.io/docs/usage/polyfill/ I've tried removing the import 'babel-polyfill'; from the beginning of "src/index.js" and it's still not working. Also tried using just the import 'babel-polyfill' instead of the entry inside webpack.config.js.

I see ... what if you not importing it. I mean using only the addition to webpack.config.js file.

I've tried every single combinations:

1. Have both the import and webpack entry: not working
2. Have only the import in index.js: not working
3. Have only the webpack entry: not working
4. Without the import and webpack entry: working (lol basically just your package so of course its working)

Thanks. I'll investigate.

Sorry about this, I shouldn't even be using babel-polyfill for a library. The reason why this doesn't work is because webpack build for the browsers but Mocha is running tests in node, so it wouldn't have the window object to store _babelPolyfill, therefore undefined. I will close this issue now.
