Node.js Web Development - Fourth Edition

Overview of this book

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. This book gives you an excellent starting point, bringing you straight to the heart of developing web applications with Node.js. You will progress from a rudimentary knowledge of JavaScript and server-side development to being able to create, maintain, deploy and test your own Node.js application.You will understand the importance of transitioning to functions that return Promise objects, and the difference between fs, fs/promises and fs-extra. With this book you'll learn how to use the HTTP Server and Client objects, data storage with both SQL and MongoDB databases, real-time applications with Socket.IO, mobile-first theming with Bootstrap, microservice deployment with Docker, authenticating against third-party services using OAuth, and use some well known tools to beef up security of Express 4.16 applications.

Node.js and the Twelve-Factor app model


Throughout this book, we'll call out aspects of the Twelve-Factor App model, and ways to implement those ideas in Node.js. This model is published on http://12factor.net, and is a set of guidelines for application deployment in the modern cloud computing era. It's not that the  Twelve-Factor App model is the be-all and end-all of application architecture paradigms. It's a set of useful ideas, clearly birthed after many late nights spent debugging complex applications, which offer useful ideas that could save us all a lot of effort by having easier-to-maintain and more reliable systems.

The guidelines are straightforward, and once you read them, they will seem like pure common sense. As a best practice, the Twelve-Factor App model is a compelling strategy for delivering the kind of fluid self-contained cloud-deployed applications called for by our current computing environment.
