I'm the author of Structor, it's really handy tool for creating UI for Web application with React components. In this article I made some introduction for Structor https://medium.com/@alex_pustovalov/structor-as-a-playground-for-react-applications-49accf4544b8#.n75e4q571
Also, I created something like a market for React components, it is convenient service which is integrated with Structor. Through this market developer can install any component into his project in form of source code generator - just like a big repository for components.
Till that time no one has tried to publish even the simplest component.
I'm really wondering, it so needless for developers to exchange with components quickly?
