When I wrote "no build", I simply meant that we do not bundle the whole app into a single file.
Fresh is indeed very close to what I'm trying to explore here, yet if I understand correctly about Fresh, we still need a real build step: https://fresh.deno.dev/docs/concepts/server-configuration#-b...
Disclaimer: I have nothing against build steps, I just wish to explore an alternative approach where we completely do without them!
