Webpack loaders are how you tell webpack to resolve your dependencies and you can use a loader built for the babel transpiler to easily enable ES6 code in your project. Full sourcemap support is also available using webpack's devtool property.

When adding Babel File Watcher in WebStorm, what should I add under 'Program'? Is the file under node modules?

Because you're doing this yourself (with webpack), I would recommend against adding the Babel File Watcher in WebStorm. It doesn't give you any benefit.

No worries. I neglected to change the JS version to ES6 :)

I'm having trouble configuring webpack to use ES6 modules like 'export default Foo'. Right now I have to use CommonJS module method 'module.exports = Foo'; Any one knows how to set this up in webpack?

Your trouble is likely because a new version of Babel was released. I recommend you install version 5 of Babel and get it working. Then use this guide to find how to upgrade to Babel 6.

Ended up installing babel-loader, babel-preset-es2015 and don't forget babel-core. To get this to work I had to add the following loader test string: {test: /.js$/, exclude: /node_modules/, loader: 'babel-loader?presets[]=es2015'}.

Now when you make the change to lame-dom-binding: "module.exports" to "export default {" it will throw an undefined unless you do this in index.js: var LameDomBinding = require('./lame-dom-binding').default;

This worked but why?
