Debugging a Reactjs front end in Adobe Premiere panel context.

Is there an example setup that would allow debugging (stepping through) front-end code developed with ReactJS? I've got the UI building into a "dist" directory and copying over all other relevant bits (CSXS folder and a jsx folder for the ExtendScript side) but I'm not sure how to set things up to be able to step through my  reactjs source. I know how to do this for a "standard" web app by running "yarn build" but not sure how to do a similar thing in the context of the Adobe Premiere Pro panel.
