I usually minify any frontend files(Angular or Ember) there is a reason behind minifying frontend files(In order to load files at lowest time and performance really does matters on browsers).
But I wonder does the Node.js code require Minification? If yes please do mention the reasoning behind it.
It is like minifying your php file. It could help load faster (let's say you have a thousand line in your file), but it just does not make sense.
Your Node JS related files (let's say, gulpfile.js for Gulp) are used for development. They are not for your website visitors to load in their browsers.

NodeJS is a platform, I can't think of a reason why would you want to minify that code. NodeJS does not have anything to do with front end development.
Minifying and concatenating scripts and styles is mainly a process for the front end.
