Moving babel config to .babelrc from package.json

[crobinson42]

In a unique case with react-native projects where babel is customized and stripped for performance reasons - js-data's package.json babel config breaks the build.

Replicate this by creating a simple react-native project and including js-data:

react-native init DemoApp && cd DemoApp && npm i js-data@rc

Now, edit the index.ios.js or index.android.js file to include import { Container } from 'js-data' then save and run the simulater

react-native run-ios

You'll see an error babelHelpers.typeof is not a function this is because babel is stripped down and customized in react-native using preset "react-native". Now, to show how this can be fixed, remove or move the babel config in the node_modules/js-data/package.json file to .babelrc and restart the simulator with --reset-cache

react-native run-ios --reset-cache

And the error has gone away!

Any objections to moving these babel configs from package.json?

We probably can, but I'll have to verify
