Thanks! It used to be a smaller version of Vue aiming to be a small subset of it. For the v1 beta (what the current documentation is for) I decided to change up the API to be something more simple that can still scale well for larger projects.
A keyed implementation, single-file components (multi-file components exist with Moon CLI but I've started to like single-file components), custom DOM events, component inserts, and an official router are on my todo list. Hopefully you'll get to use the library this time :)
