Solid NodeJS book that teaches you how to use NodeJS strong points.
Part 1 is definitely a must-read and really well explains NodeJs buffers and streams. No bullshit, only quality stuff. Probably my most favourite NodeJS book part/section I've read.
I really like the "problem, discussion, solution" approach of the book. It makes reading and understanding the contents much better.
Part 2 is the standard nodejs webapp bullshit that you can skip.
Part 3 is relatively short - only one chapter on writing node modules, but it covers interesting topics such as benchmarking, sem versioning (finally people will learn how to use/understand it).
I would recommend this book for anyone wanting to learn how to properly utilize Node's strong points.
