Express error handling sample

Little project focused on Nodejs error handling through Express middlewares.

The goals are:

• handle errors that can crash the node process (in the "let is crash" way)
• define a set of standard lightweight erros that will be returned to the client (web app), hiding the complexity of the real error happened
• log operational and programmers errors with a logger so that it is possible to reconstruct what happened

Disclaimer

No attention is made to topics such as validation, code structuring, databases, etc. Only error handling!
