How to upgrade a React project built with create-r

问题:

I have a React project built with create-react-app 1.5. I would like to get the features of create-react-app 2.0 for my React project.

Specifically I would like to use this: https://github.com/facebook/create-react-app/pull/3909

Basically, to upgrade a create-react-app project, all you need to do is update the react-scripts module to the latest version and update your app to be compatible with any breaking changes in react-scripts.

Run yarn upgrade --latest react-scripts, rebuild your app, and everything should more-or-less work, barring any breaking changes.
