Node.js in Action, Second Edition

This book is the Chinese translation of the second edition of Node.js in Action, part of the Turing Programming Series, written jointly by several contributors to Node.js core frameworks and active community developers. The book is built around a single main thread—"building production-grade applications on the server side with JavaScript"—and is divided into three parts. Part One lays the foundation: it explains Node's non-blocking I/O and event-loop model, the relationship between Node and V8 and ES2015 versions, installation and the bundled npm, core modules, and the debugger, as well as the three main forms of Node programs—web applications, command-line tools and background daemons, and desktop applications; it then covers module organization and getting a project started, and HTTP services and the middleware-style structure of web applications. Part Two moves into hands-on web development: front-end build systems, comparison and selection of server-side frameworks, in-depth use of Connect and Express, server-side templates such as EJS, Mustache, and Jade, integration of databases and storage solutions, testing Node programs (including unit tests and functional tests), and deployment and operations (PaaS, servers, containers, Git deployment, saturating multiple cores with the cluster API, static files, and reverse proxies). Part Three goes beyond the web: writing and publishing command-line tools and pipeline scripts, and building cross-platform desktop applications with Electron. The appendices also provide guidance on installing Node, automated web scraping, and a quick reference to Connect's official middleware.
