React is not the best way to do MVC, as it's too opinionated. But the architecture looks promising.
Sorry, but is React "too" opinionated? I don't think so. In this example MVC is applied seamlessly and React just handles View part of MVC which makes it less opinionated than the others.
Thanks for the comment. React is actually not that opinionated, which makes it the best view library at the moment. Take a look at the project and I'm sure you'll find yourself at home if you are into MVC :)
MVC is still my favorite UI architecture, using it with React is so exciting. Will get my hands on!
It actually looks like MVVM, rather than MVC.
Technically you are right, more like MVVM, but MVC is an umbrella term nowadays.
