The Framework is new but has what it takes to take your apps to the next level, right now rails 5 is beta with ActionCable to make real time but I must say ruby isn't the right tool for doing real time but Elixir is really fast and has great concurrency and other erlang features.
I found mean.io just smooth, fun, orginized and just work out-of-the-box.
MongoDB is a solid NoSQL store. Angular.js is being vetted as a potential front-end framework for the website (though it may ultimately not be used for the non-app site). Everything is running on node.js and hosted via an Express.js web server (though we are looking into Koa.js as it is the official successor to Express.js)
FULL STACK ( preferred if;at all possible! ). Any "NEW" project (all me) I am tasked with I try to sketch it out with MEAN in mind first and then will tweak or stray from the 'plan' when necessary
