Wow this looks awesome! I've been using Alpaca.js [1] at FormAPI [2], which is also a JSON Schema form builder. This looks much better, and much easier to customize, since I already use React / Redux / React DnD for other parts of the application. I was also looking at react-jsonschema-form, but agree with all the downsides they mentioned in the talk (hard to customize, requires Bootstrap, hard to use with Redux, etc.)
So I think I will definitely switch to ShapeForm in the future, and I was actually planning to build something like this myself. I'm definitely looking forward to the TypeScript support.
