Mastering Node.js - Second Edition

By: Sandro Pasquali, Kevin Faaborg

Overview of this book

Node.js, a modern development environment that enables developers to write server- and client-side code with JavaScript, thus becoming a popular choice among developers. This book covers the features of Node that are especially helpful to developers creating highly concurrent real-time applications. It takes you on a tour of Node's innovative event non-blocking design, showing you how to build professional applications. This edition has been updated to cover the latest features of Node 9 and ES6. All code examples and demo applications have been completely rewritten using the latest techniques, introducing Promises, functional programming, async/await, and other cutting-edge patterns for writing JavaScript code. Learn how to use microservices to simplify the design and composition of distributed systems. From building serverless cloud functions to native C++ plugins, from chatbots to massively scalable SMS-driven applications, you'll be prepared for building the next generation of distributed software. By the end of this book, you'll be building better Node applications more quickly, with less code and more power, and know how to run them at scale in production environments.

Understanding Asynchronous Event-Driven Programming

"The best way to predict the future is to invent it."
– Alan Kay

Eliminating blocking processes through the use of event-driven, asynchronous I/O is Node's primary organizational principle. We've learned how this design helps developers in shaping information and adding capacity. Node lets you build and organize lightweight, independent, and share-nothing processes that communicate through callbacks and synchronize with a predictable event loop.

Accompanying the growth in the popularity of Node is a growth in the number of well-designed event-driven systems and applications. For a new technology to be successful, it must eliminate the existing problems, and/or offer to consumers a better solution at a lower cost in terms of time, effort, or price. In its young and fertile lifespan, the Node community...
