process-uncaughtException.js

var sys = require('sys'),
    http = require('http');

process.on('uncaughtException', function (err) {
  sys.puts('Caught exception: ' + err);
});
    
// Simple Example
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.write('Throwing exception')
  res.end();
  throw new Error();
}).listen(8080);

// Type Error
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.write('Throwing exception')
  res.end();
  
  var myObj = {};
  myObj.doesntExist();
  
}).listen(8081);

Yes, but this leaves the client hanging..

Hmmm.... you're right. But the uncaughtException event is all about your request / response then why not just:

http.createServer(function (req, res) {
  try {
    // Entry point for all your server logic
  } 
  catch (err) {
    // Respond to client based on error
  }
});
