Defyne is actually usable... Great stuff !

Can you add some test projects ?

It would make it easier to experiment and also for me and others to help. Maybe a "ProjectTests" folder in the repo for now ?

I got some various widgets working and understand how the system fundamentally works. Seems to maintain a json description and then gen the golang from that json. It would be nice if a basic docs folder explained this, again so that others can help.

I am curious that is the architectural plan to add logic. For example click a button and change some text.
