I am new to Node.js and am currently questioning its reliability.
Based on what I\'ve seen so far, there seems to be a major flaw: any uncaught error/exceptions crashes
Exceptions don't crash the server, they raise exceptions.
Errors in node.js that bring down the entire process are a different story.
Your best bet (which you should do with any technology), is just test it out with your application as soon as possible to see if it fits.
