@jrwdunham What you have in the ‘datahike-frontend’ project is a Fulcro application connecting to a Datahike server through a REST API. In this setup Fulcro’s backend is not really used. But initially I tried a different configuration where we fully exploit Fulcro’s full stack nature, i.e., run Datahike as part of Fulcro’s backend. This worked very well as well. And it is worth mentioning that in both configurations you can use Pathom.
