Add react config

Note: existing "create-react-app" does not match these requirements. We should be able to create react library which exports hooks/components

I'm also curious if there's a plan to add a sensible default for react based libraries.

React isn't a runtime (next, docusaurus, gatsby are for example) so it's pretty unlikely - can you provide some examples of what you are thinking of?
