In the latest version of react-jss (2017-06-28) that yarn installs, there are breaking changes:
- Removed `createInjectSheet`. Use JssProvider to pass a `jss` instead instead.
- Renamed `SheetsRegistryProvider` to `JssProvider`See changelog.md inside node_modules. It doesn't show up in the github repo README for some reason.
Let me know if you want me to submit PR for the JS-Stack-Boilerplate repo. Thanks for all the hard work on this. Learned a lot!
