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.

Summary

Node provides a set of tools that help in the design and maintenance of large-scale network applications facing the C10K problem. In this chapter, we've taken our first steps into creating network applications with many simultaneous clients, tracking their session information and their credentials. This exploration into concurrency has demonstrated some techniques for routing, tracking, and responding to clients. We've touched on some simple techniques to use when scaling, such as the implementation of intra-process messaging via a publish/subscribe system built using a Redis database. We also touched on various authentication mechanisms, from basic authentication to token-based authentication with JSON Web Tokens.

We are now ready to go deeper into the design of real-time software—the logical next step after achieving high concurrency and low latency...
