node.js, catching errors so script doesn't break?

Question

I have a node.js script and anytime an error happens node.js stops running with the error that happened.

What is the proper way of checking errors in node.js so it w

Answer 1

Catching uncaughtException is no longer recommended.

Using domains are preferred. Using either "uncaughtException" or Domain, restarting the process is highly recommended after handling the exception.

To auto-restart the process, NodeJS provides another library called Cluster which assists in managing the worker threads.

Answer 2

You can catch otherwise uncaught errors by setting the following:

process.on('uncaughtException', function (exception) {
   // handle or ignore error
  });

Of course, if you run your script in something like forever or node-supervisor, when your script "stops" it will start back up, which might solve your problem.
