This is really awesome! How are you finding Funscript? Last I tried to look at it following the tutorials to get started was not a smooth process due to being out of date. It's also, unfortunately, not a terrible active project :|
But i still like it and managed to create fancy stuff with it - Ionide, React.js + Material UI applications etc. Wouldn't recommend using it on production ( unless You want to commit really hard into FunScript project and probably fix lot of this stuff) - WebSharper is providing more complete, richer solution and commercial support if needed
Intellifactory's Websharper projects are well supported and regularly updated, you could try Websharper.Warp[2] in lieu of FunScript.
