Node.js in Action

Node.js in Action is a tutorial in the Turing Programming Series · Web Development that gives equal weight to the basics and to hands-on practice with Node.js. The original English edition, Node.js in Action, was co-authored by Mike Cantelon, Marc Harter, T.J. Holowaychuk, and Nathan Rajlich, core contributors to the Node.js community, and translated into Chinese by Wu Haixing. The book is organized around a single question—how to build production-grade server-side applications with JavaScript—and is divided into three parts. Part 1 covers the foundations of Node: it begins with installation and configuration, uses a multi-room chat application to give readers an intuitive feel for event-driven, non-blocking I/O, and then systematically lays out the Node programming basics: the module system, callbacks, event emitters, and more. Part 2 focuses on developing web applications with Node: building HTTP servers and REST interfaces, data storage options (files, relational databases, and document databases), Connect and its bundled middleware, the Express framework and advanced usage, application testing, and template rendering. Part 3 goes further: it covers deployment and keeping services up and running, application forms beyond the web server such as TCP/IP servers and command-line tools, and the Node ecosystem and common community modules, and includes three appendices on installation, debugging, and Express configuration. The book is characterized by clear conceptual explanation, examples close to real projects, and coverage of the full path from setting up an environment to deploying to production; it is suited to readers who already know JavaScript and want to make a systematic move into server-side development.
