The babel preset needs to be refined, but the configuration swap works perfectly.

package.json, line 18 at r1 (raw file):

    "react-on-rails": "12.2.0",
    "react-on-webpacker": "^0.0.1-beta.0",
    "style-loader": "^3.3.1",

should the style-loader be a dependency of react-on-webpacker

@Judahmeek @gscarv13 can you update this PR? I just updated https://github.com/rails/webpacker/pull/3224/files so we could have a demo of all the react stuff is in the package https://github.com/shakacode/react-on-webpacker

And we need some docs for that.

@Judahmeek can we get this updated ASAP.

@mrtnzlml @Judahmeek @tomdracz,

Is this PR still useful? Or should this:

1. Be within shakapacker
2. Be within documentation
