What's the difference between Relay and other Flux inspired libraries like Redux?
There is no difference, Relay is just another Flux option.
Relay is meant for React Native apps, you should stick with Redux for web apps.
Relay helps scale your Flux architecture by allowing data dependency declarations and hiding all of the server communication complexity.
How does Relay simplify the data requirements of React components?
By collocating the data dependency queries, you can see exactly what data your components use without having to sift through code that does the fetching.
By fetching all of the application data upfront, Relay can then query locally for data that each of your components need.
