Nice. I honestly have been looking for something like this for awhile. All the examples I found with slate were either insufficient or outdated (i.e. canner editor) -- and in a focus on speed (being a solo founder), I couldn't compromise. I'm going to try to implement this for my editor on my site. Would be cool to be able to publish content with custom components (closest I could find for CKEditor [which I'm using] is: https://ckeditor.com/docs/ckeditor5/latest/framework/guides/...) -- but the implementation for that is rather clunky (more so on the render side -- e.g. how do I save the data in my database such that I know which components to call? CSS classes? data attributes?) So the underlying structure of having JSON for the data structure with Slate (and now this) gives me more confidence as a dev.
