Set jsonpFunction by default

[sibiraj-s]

Hi,

jsonpFunction, is set by default to prevent conflicts within app when multiple webpack runtimes (from different compilation) are used on the same webpage.

For example, a widget built with webpack being loaded into a site which is too webpacked.

@ianschmitz any update on this.

@sibiraj-s, I'd love to help you get this through.

This seems to introduce a different issue, in two apps built in CRA would still conflict. Could we use the app name instead? It's available within the config as a variable.

Yeah. I didn't think of that. Will update.

Thanks, let me know when that's done @sibiraj-s - I think we can land this in 3.1 if you can get it done in the next few days.

Sorry, you're right!

Just require in the package.json as we do here: https://github.com/facebook/create-react-app/blob/47e9e2c7a07bfe60b52011cf71de5ca33bdeb6e3/packages/react-scripts/scripts/init.js#L88

Then you can use appPackage.name :)
