Stimulus: A modest JavaScript framework for the HTML you already have
I don't mean to knock the effort they've put in here, but this looks like all of the hand-rolled "frameworks" I saw my friends in the agency / consulting space made when they said angular 1 was "too heavy"... right down to the 'data-controller' attribute binding that everyone seemed to independently come up with.<p>Is there anything actually novel here? These types of things always seemed to run into composition issues (controllers inside of controllers) in terms of communication and what not.  The net result was invariably far less appealing than, say, angular 1 or vue or non-SPA React.
