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.

Serverless applications

The abstractions that emerge from the design of these distributed systems, largely built on microservices, suggest a natural next step. Why have servers in the traditional sense at all? Servers are big, powerful machines designed in the age of monoliths. If our thinking is in terms of small, resource sipping, independent actors indifferent to the world around them, shouldn't we be deploying microservices to "microservers"? This line of thought has led a revolutionary ideas: AWS Lamda.

AWS Lambda

The introduction of Amazon's AWS Lambda technology boostrapped the serverless movement we have today. Amazon describes Lambda like this:

"AWS Lambda lets you run code without provisioning...
