@torb So, I haven't got that far yet in the side-project that's driving this 🙂️
But, I'm inclined towards minimalistic solutions in general so I'm leaning towards Deno on the serverside using individual worker-friendly libraries for routing and rendering. Like uhtml/uhtml-ssr and itty-router. That sort of thing.
Or I might look at something like Deno and lume.land. I've used Lume on other projects. There's a lot of options now, thankfully. Which is a definite improvement over a few years ago.
