Who this book is for

This book is for developers who want to build high-capacity network applications, such as social networks, collaborative document editing environments, real-time data-driven web interfaces, networked games, and other I/O-heavy software. If you're a client-side JavaScript developer, reading this book will teach you how to become a server-side programmer using a language you already know. If you're a C++ hacker, Node is an open source project built using that language, offering you an excellent opportunity to make a real impact within a large and growing community, even gaining fame, by helping to develop this exciting new technology.

This book is also for technical managers and others seeking an explanation of the capabilities and design philosophy of Node. The book is filled with examples of how Node solves the problems modern software companies are facing in terms of high-concurrency, real-time applications pushing enormous volumes of data through growing networks. Node has already been embraced by the enterprise, and you should consider it for your next project.

We are using the bleeding-edge version of Node (9.x at the time of writing). This is the only book you need to be ready for in the next few years as Node continues its march through the enterprise.
