Ask HN: Any body know of simple live editable HTML pages?

I saw this post about slate.js [https://docs.slatejs.org/] a couple of days ago. A decent live editable web page/blog has been on my wishlist for years. Seeing slate.js in demo feels very close to it, but I don't know how I can make it just save the edited content onto a live HTML. Could anyone who knows JS and is aware of slatejs show me a bare-bones layman's example of how I can use it for my blog? I want to be able to go to a url, edit the content, and see it published right away, without going to command line at all.
