I liked what I saw for the most part. Towards the end there's a section on Mongoose in the persistence chapter that's really skimpy and the chapter after that talks about how to get Node to work with AngularJS, which I have not yet learned how to use. After this is some more advanced stuff about dealing with complications in developing Node applications, including a chapter on managing the complexities inherent in multiple callbacks and the alternative of using promises, which I skimmed. It seems fairly opaque to me now, but I might just be being dense. Anyway I can still solidly recommend the first half and then some. If I go further into Node, the latter half or so is something I may come to rely upon as reference material that makes sense for someone who has / needs increasing sophistication with the subject matter.
