I've found a solution. I'm sure your answer helps someone with a different problem. On Fri, Jul 27, 2018 at 7:47 AM, Sridhar Ratnakumar < pervasiveproximity@gmail.com> wrote:

This doesn't directly answer your question, however in the case that all you want is to get started with a simple Reflex-DOM app, I'd suggest starting with obelisk: - https://github.com/obsidiansystems/obelisk - https://youtu.be/riJuXDIUMA0?t=30m15s

Then you can just run `ob repl` to get into the repl.
