Instead of running clj -M:dev dev, you can call the -main function from the repl: https://github.com/jacobobryant/biff/blob/146f2b1c8e0563bd288795851beae8b985cacac7/starter/src/com/example.clj#L86 to stop, see the first part of the refresh function: https://github.com/jacobobryant/biff/blob/146f2b1c8e0563bd288795851beae8b985cacac7/starter/src/com/example.clj#L90. you could extract that (the doseq) into a stop function. The clj -M:dev dev command also handles project init (e.g. creating a config.env file if there isn't already one) and starting up the tailwind watcher. For init you can just run clj -M:dev dev at least once when creating/cloning a project, and for the latter you can run clj -M:dev css --watch in a separate terminal. (see https://github.com/jacobobryant/biff/blob/146f2b1c8e0563bd288795851beae8b985cacac7/libs/tasks/src/com/biffweb/tasks.clj#L262)

actually you'll want to call start, not -main -- only difference is that -main starts up an nrepl server which you'll already have. also if it's helpful, you can run clj -M:dev nrepl to get an nrepl server without also doing the other stuff that clj -M:dev dev does.

Yeah I've generated the initial files by running clj -M:dev dev , then I'm simply starting a repl in calva from the polylith root and I try to run start but it just immediately kills my nrepl. No worries though, I can work around it for now. By the way, the Biff framework is awesome! I really appreciate the work you've put into it!

huh that's weird; not sure why it'd be killing nrepl. FWIW I just tried starting up the example project with clj -M:dev nrepl and then calling (start) and it worked as expected. glad to hear Biff's been helpful!

Ah yes, that method does work for me as well. That's a good compromise. Thanks so much!
