I get where you're coming from. Sometimes I just want to make the thing and for nothing to get in the way. Other times I want to try out a new language or framework to see if it does things in a more fun, less fussy way.

For the first kind, I'll make a single fullstack repo that hot-reloads both server (maybe F#, Kotlin, Go w/Generics?) and client (Vue/TS) locally on autosave, and deploys on commit/push. That's fairly frictionless to my expectations.

You could also solve the metaproblem, make things more fun, streamline out all the unfun things in your toolchain/process.
