Interesting project! I recently created something similar[1] because I wanted a simple, easy to use, bloat-free micro framework to create single page applications. I also wanted it to be somewhat "battery-included" and provide things like routing and state management out of the box.

I think skruv comes with even bigger batteries (SVG support, Shadow Dom integration and additional vdom related apis), and I am curious to see how they all play together. The one thing that does seem a bit weird is the html helper functions... like Mithril, I went straight for hyperscript: I think it is very underrated right now but it is actually a good way to write a dom tree -- and you also get JSX support (nearly) for free.

Anyhow, keep up the good work, I think the world needs more micro frameworks like these: powerful but simple enough to be understood and extended easily if needed.
