I would do pretty much exactly what OP suggests. I might just go for React+Redux instead of MobX, but that's not too important. What I'd like to hear is arguments as to why I might want to consider other options. Why Elixir, compared to the above solution? Why Phoenix, or for that matter Django? Or for the front-end-ish side: why MobX instead of what seems to be a more industry-standard Redux? Why Node.js and Express instead of the alternatives (Django, Rails, but also Hapi and Sails)?
