This is a really great intro. I like how it expands on the basic flux diagram that I see everywhere. One thing missing from many flux tutorials and sample applications that I would love to see included is error handling. How do you manage errors in your flux applications? Do you keep them in the store? If using something like react-router, how do you ensure you flush errors from the store as your routes change and they are no longer applicable to the data in view?
