You can get the same functionality by using an existing state manager, a socket library, and your own tree diffing algorithm. This is just a baked pie ready to eat, along with some syntax sugar :)
Here is a very simple example usage: https://github.com/mstdokumaci/stx-vue-example
I get the picture, looks really useful. Maybe the tagline "Batteries included data structure / state manager." Could be something more like "minimal web socket synchronized state manager" or something like that.
Since it helps most with keeping same content sync among multiple devices, I assume it's a good fit for any kind of content publishing. Want to compete with Medium or Netflix, here you start :)
