Express is a fast, unopinionated, minimalist web framework for Node.js. That's why I had to purchase yet another book to add to my huge collection of computer books.

I sawed through this book in a single day. While it may not be intended for super advanced developers, I found it a refreshing overview of express, node, npm and all those powerful tools and techniques any engineer worth his salt should know.

There's also a nice section covering testing with mocha and supertest, as well as chapters about mongodb, less, browserify and coffeescript.

Highly recommended by someone who is never too old to learn new stuff.
