The Flux pattern contains too much boilerplate and indirection for small or quick one-of web apps. If Marty helps to abstract some of that out, it's more than welcome to me.
Frankly, for small apps, I think you can get 90% of the benefit of Flux by using the pubsub solution of your choice and taking care about only subscribing from top-level components and passing state change down to their children. Immutable cursors are also a nice solution for small apps.
I get that for large teams working on massive code bases, and possibly even for smaller apps, Flux is a big plus. But I'm glad that projects like Marty are working on abstracting out all the boilerplate. Less code for me to worry about.
I find that small apps tend to turn into big apps over time, and Flux lets us build with the confidence that, as new features are developed, our apps won't have to be deeply rewritten. New, unexpected features tend to fall into place with Flux, with a minimum of effort. I have seen this time and time again in working with Flux.
