This looks really nice. I have a question about React Native though. I was under the impression that React Native meant that you could just take your components from your website and build an app out of it. I'v realized that's not the case. What is the benefit of React Native if you can't share the components?
You can share some components, especially more abstract ones. For example, react-redux creates higher-order components that work with both React DOM and React Native. There's also a project called react-native-web that implements React Native's View components using React DOM's primitive components (https://github.com/necolas/react-native-web).
Components aside, you can share your models and data stores, utilities like Immutable.js and lodash, and other environment-agnostic JavaScript. In addition to code, you can share a lot of knowledge like how to write components, structure an app, use npm, and even just write JavaScript.
