I don't know enough to answer your question - I'm just embarking down the cljsrn rabbit hole myself - but I did spot a template using Krell+Storybook that might have some hints https://github.com/joshuamiller/react-native-template-cljs-krell-storybook

As far as I understand, in this example, the Storybook components are not written in CLJS. So I wondered if Krell could build the CLJS stories for the Storybook.

I have been able to integrate CLJS components with components developed with Storybook. The Storybook components are integrated with CLJS by requires, so they didn’t interfere with anything else I was working on.
