I actually just wrote a Node + Express + Backbone error handling system today. I've been staying sane through the use of the 'Q' promise package (https://github.com/kriskowal/q https://github.com/kriskowal/q). For example, in the below code chunk any errors thrown in makeEmailConfirmation or sendEmailConfirmation will land in the .fail() catch block. I believe using a promise system is the only way to avoid callback hell. var deferred = Q.defer(); ... Storage.CustomLinks.makeEmailConfirmationLink(user) .then(function(link) { return Email.sendEmailConfirmation(user, link); }) .then(function(result) { deferred.resolve(result); }) .fail(function(err) { deferred.reject(new ServerError(err)); }) .end(); ... return deferred.promise;
