Members of the Node community develop new packages and projects every day. Because of Node's evented nature, callbacks permeate these codebases. We've considered several of the key ways in which events might be queued, dispatched, and handled through the use of callbacks. Let's spend a little time outlining the best practices, in particular, about conventions for designing callbacks and handling errors, and discuss some useful patterns when designing complex chains of events and callbacks. In particular, let's look at the new Promise, Generator, and async/await patterns that you will see in this book, and other examples of modern Node code.

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.
