Can't you just use node-mysql or something like that? They broke my heart when they dropped custom runtime (and ML-like syntax) in favor of Node and JS, but it should allow Opa users use Node libraries directly, no?

I like the idea of such a "framework" - it's time to abstract away all the cruft web developers need to write and focus on actual logic. I didn't use Opa or anything similar yet, but I'm keeping an eye on them and will try them at some point.
