title: How can I get express.js to catch and report runtime exceptions in AJAX calls
body: <p>I've found that when I have runtime errors (for example, reading an undefined property from an object) in a GET handler in express.js, Express is great at giving me feedback in the browser as to what the problem is and with a full stack trace. </p>
  
  <p>However, when I have runtime errors as a result of an Ajax POST call, I don't get the same level of feedback and the Node console is sadly silent on the matter. </p>
  
  <p>Is this an Express configuration issue? </p>
