Error handling with Mongoose

I am an absolute NodeJS beginner and want to create a simple REST-Webservice with Express and Mongoose.

Whats the best practice to handle errors of Mongoose in one central place?

When anywhere an database error occurs I want to return a Http-500-Error-Page with an error message:

if(error) {
  res.writeHead(500, {'Content-Type': 'application/json'});
  res.write('{error: "' + error + '"}');
  res.end();
}

In the old tutorial http://blog-next-stage.learnboost.com/mongoose/ I read about an global error listener:

Mongoose.addListener('error',function(errObj,scope_of_error));

But this doesn't seem to work and I cannot find something in the official Mongoose documentation about this listener. Have I check for errors after every Mongo request?
