Getting a node.js process to die?

I'm trying to find the most elegant way for my node.js app to die when something happens. In my particular case, I have a config file with certain require parameters that have to be met before the server can start and be properly configured.

One way I have found to do this is:

var die = function(msg){
    console.log(msg)
    process.exit(1);
} 

die('Test end');

Is there a better way to handle this kind of situation?
