內容簡介
Node.js是一個由JavaScript書寫而成的強大的web開發框架，它讓開發強壯的、伸縮性良好的服務端web套用變得更加簡單，容易。本書向你展示了什麼是Node以及如何讓你在項目中使用它。本書包含大量實際套用中的示例程式，證明了為什麼Node.js會快速成為web開發首選工具的原因。
本書是一本經典的 Learning by Doing的書籍。它由 Node社區著名的 Socket IO作者Guillermo Rauch，通過大量的實踐案例撰寫，並由 Node社區非常活躍的開發者 GoddyZhao翻譯而成。
本書內容主要由對五大部分的介紹組成： Node核心設計理念、 Node核心模組API、Web開發、資料庫以及測試。從前到後、由表及里地對使用 Node進行Web開發的每一個環節都進行了深入的講解，並且最大的特點就是通過大量的實際案例、代碼展示來剖析技術點，講解最佳實踐。
