Node.js web development

Description

Node.js is a server-side JavaScript platform using an event driven, non-blocking I/O model allowing users to build fast and scalable data-intensive applications running in real time. 'Node.js Web Development' shows JavaScript is not just for browser-side applications. It can be used for server-side web application development, real-time applications, microservices, and much more.;Cover; Copyright; Credits; About the Author; About the Reviewer; www.PacktPub.com; Table of Contents; Preface; Chapter 1: About Node.js; The capabilities of Node.js; Server-side JavaScript; Why should you use Node.js?; Popularity; JavaScript at all levels of the stack; Leveraging Google's investment in V8; Leaner asynchronous event-driven model; Microservice architecture; The Node.js is stronger for having survived a major schism and hostile fork; Performance and utilization; Is Node.js a cancerous scalability disaster?; Server utilization, the bottom line, and green web hosting.
