Node.js + Express+ SocketIO on the server side with Angular on the front end.

For my apps I have a loose framework that I built over the years with pub-sub model between client and server and similar within the server side code itself.

Node was an easy choice since I love JS and having only one language reduces cognitive load a lot.

Express is a well known mature framework, similar with SocketIO even though it has some warts.

Angular is similarly a mature framework which I use in s quite simple manner to tie pieces of code together so i haven't had any performance problems. And since I work in enterprise it is still very a very popular choice and none of the issues with strange licensing or complicated transpiling build systems.
