ReactJS Architecture: Part 1

The Why

React is awesome. 11/10. In my opinion, the best UI library currently in the ecosystem. It streamlines UI componentization, reusability, UI state, and a ton of other client side headaches devs have been mitigating for years. React's greatest flaw, in my opinion, isn't even really a React flaw as much as a "new stuff hype" flaw, where the infrastructure surrounding React changes almost hourly and can be extremely difficult to keep up with. What libraries are required, which ones will make devs' lives easier, which will bring performance gains?
