Node.js Guidebook aims to introduce readers to the world of Node.js. Node.js is an open source JavaScript run-time environment that executes JavaScript on server-side. Earlier, JavaScript was used only for client-side scripting, but Node.js supports the creation of dynamic Web applications by using JavaScript for server-side scripting. Node.js has taken the world by a storm by simplifying Web application development thorough the use of readily available and pluggable modules, thus, reducing the overall development time. Whether you are a beginner or an experienced developer, you can learn to design and develop attractive and efficient Web applications using Node.js.
This book intends to familiarize the reader with the basic and advanced concepts of Node.js. The book begins with an introduction to the features and tools of Node.js and proceeds to explain the use of different modules in Node.js. It explains the concepts in a detailed but simple format along with codes and detailed steps of demonstrations. You will learn to implement different modules and manipulate databases with Node.js. The book concludes with an explanation of Express module which is a minimalist Web framework for Node.js.

Node.js is an evolving technology and gets upgraded regularly. Thereby, covering all updates is beyond the scope of this book. The book also assumes that the reader has basic knowledge of JavaScript and HTML technologies. It serves as a guide for beginners as well as experienced developers aspiring to begin development using Node.js. It has been written after extensive research and reference from different Node.js sites, blogs, books, articles, discussion forums, etc. Any shortcomings of the books are purely due to commercial and scope constraints.
