Real-Time is not possible on Node.JS

[minecrawler]

Because Node.JS is a garbage-collected language with a work-queue. That means there are no guarantees for runtimes, hence no real-time guarantees. Maybe you wanted to use a different meaning here, but the word is just wrong.

See for example the definition on Wikipedia, which quotes Ben-Ari, M., "Principles of Concurrent and Distributed Programming", Prentice Hall, 1990. ISBN 0-13-711821-X. Ch16, Page 164.

This heavily depends on how you define "real-time" in your system. In programming sense of the word node may not make real-time possible but node based systems can be "real-time" from more business oriented perspective. The very article you quoted mentions that

in process control and enterprise systems to mean "without significant delay"

If you are fine with business definition of real-time then node can give you a real-time web application.
