I know a fella working on a Deno port of Ava (https://github.com/avajs/ava). When that and Koa are ported or compatible, I'll be giving Deno a legitimate go.

FYI https://github.com/oakserver/oak is a port of Koa for Deno.

Deno test has been fine. oak exists for koa like middleware oriented servers
