My latest book about Node.js is ready (Jul, 2014)!
Practical Node.js was designed to be a one-stop source for going from hello-world examples to building apps in a professional manner. The libraries covered in Practical Node.js greatly enhance the quality of code and make developers more productive.
You can get it on Amazon, B&N and Apress directly. Also, Apress has the ebooks in all formats.
The book’s website is at practicalnodebook.com. And the examples’ code is freely available at github.com/azat-co/practicalnode.
