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.

Organizing Your Work into Modules

"Complexity must be grown from simple systems that already work."
– Kevin Kelly, “Out of Control”

Node’s straightforward module management system encourages the development of code bases that grow and remain maintainable. The Node developer is blessed with a rich ecosystem of clearly defined packages with consistent interfaces that are easy to combine, delivered via npm. When developing solutions, the Node developer will find many pieces of the functionality they need ready-made, and can rapidly compose those open source modules into larger, but still consistent and predictable, systems. Node's simple and scalable module architecture has let the Node ecosystem grow rapidly.

In this chapter, we will cover the details of how Node understands modules and module paths, how modules are defined, how to use...
