Not a Fad! It is a solid workhorse! Configuring Node servers is hardly an issue - maybe 5 minutes work. Writing services to run on Node does require some JS experience and becoming comfortable with the asynchronous nature of the Node environment. But most efficient browser side code is written in the same style. Node shares the v8 JS engine with Chrome - so it is a high performance environment to write services for. Being able to use the one language, JavaScript aka ECMAScript, on both the server and browser is going to ensure longevity with lots of experienced programmers. Will something "better" come along? - given enough time, YES! Is it suitable for any task you may think of? - NO! It is unlikely that we'll ever see a truly capable Swiss Army Knife of software engineering - not that I'd try to fix my car with a SAK either!
