Node.js technology is still young and at the same time has been around long enough for large corporations (LinkedIn, Yahoo! and Netflix) to adopt it. This book is about Node and the modules that make up the core functionality of Node. You'll start with the basics of creating a web server and basic functionality, and then move on to the module system, REPL, application development, security issues, child processes, new features introduced in ES6, end-to-end development (Express, MongoDB, Redis, AngularJS and Backbone.js), application development techniques, and finally using Node in other areas such as microcontrollers and the Internet of Things. 2nd edition, revised and expanded.
