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.

Closing thoughts

Being able to easily link C++ modules with your Node program is a powerful new paradigm. It may be tempting, then, to exuberantly begin writing C++ add-ons for every identifiable segment of your programs. While this might be a productive way to learn, it is not necessarily the best idea in the long run. While it is certainly true that, in general, compiled C++ will run more quickly than JavaScript code, remember that V8 is ultimately using another type of compilation on the JavaScript code it is running. JavaScript running within V8 runs very efficiently.

As well, we don’t want to lose the simplicity of organization and predictable single-threaded runtime of JavaScript when designing complex interactions within a high-concurrency environment. Remember that Node came into being partly as an attempt to save the developer from working with threads and related...
