Nathan,
It appears to me that Node.js is more suited for "simple" "applets".
I'm too new to node to argue against this claim. But I do know that node is being used by companies like Walmart, LinkedIn, PayPal, NetFlix, Dow Jones, and more. Walmart released node on Black Friday of 2013 to handle their mobile traffic (about half of all www.walmart.com traffic). LinkedIn is using node for all of their mobile. Are the companies just listed using node for "simple applets," as you are conceiving simple applets?
Thanks,

A developer can also create "sub-apps" or modules within a "node app"
using ExpressJS router and module.exports. "Sub-apps" do not have
their own port numbers.
Here's a little bit of trivia; when I click on the link to "expand" this conversation in Gmail, it leads to a 1.8 Megabyte download. Maybe someone should start a new thread ;-)
Kelly,
It appears to me that the idea of "sub-apps" in Express.js is a "router"
within a "router". A "sub-app" is NOT an otherwise functional application, if I understand correctly.
Given the already obscure interface exposed by Express.js, their idea of "routers" within "routers" or "apps" within "apps" becomes even less clear.
They use regular expressions including wild-card characters to compare "routes" to URL "paths" which is another difficult concept. There is quite a bit of "overhead" in matching URLs with regular expressions.
After more thought, I'm still hung-up on the "necessity" of restarting a Node.js service every time a routing configuration changes, which occurs with every new "functional application" that is added to the service (every new URL which is defined). We're adding new applications to our Web portal daily during "sprints".
The need for an external router which includes fail-over support would be an absolute requirement. When you combine "applications" with "routing" and "HTTP services" in a single process, developers come up with all kinds of unforeseen ways to bring down the entire lot. Maybe it's as simple as a condition that results in a continuous loop. And it's unclear what may have caused it.
It appears to me that Node.js is more suited for "simple" "applets".
