Hey HN,
I've been wanting to move away from from JavaScript frameworks and use equally powerful libraries with a fraction of the bandwidth cost, and recently did so with my game engine's GitHub Pages site.
I wanted routing still, and markdown to HTML conversion, since I'm pulling from .md files on our GitHub wiki section.
Here's what the website looks like now:
http://planimeter.github.io/grid-sdk/
And here are the libraries I wrote to make the transition:

https://github.com/andrewmcwatters/route.js
