Which one?
The one with webpack? 1? 2? Now 3?
What about react? And redux. And react HMR. Oh and you probably need immutable.js if you want to use react the 'proper' way not like those fools last year. Your starter script was configured with react-router? That's a shame, because it's no longer the latest and greatest, and everyone knows you should have moved on to React Mini Router. Or is it React Universal Router now? Wait is the particular configuration of webpack in this starter script even compatible with the latest and greatest babel-loader? Hang on, you wanted to use promises? Yeah, that's another plugin for polyfill and more config that interacts with most of the above. Don't worry though, there's plenty of tutorials to get it working with webpack... Oh wait, they're all for webpack v1 and you're on v2.
