[keeeeeeeem]

David Nolen gave a relevant talk[0] about the workflow they use to integrate Clojure and React Native for mobile and web development at the company vouch.io. You say "I'd like to reuse the frontend part of the web app", their methodology involves using Storybook.js to ensure their React components are truly stateless and may be re-used across environments.

As I understand it they have released some of their mobile dev REPL tooling under an open-source license (Krell).

Good luck!
