Authors Luciano Mammino and Mario Casciaro offer a practical guide that unpacks the JavaScript runtime so you can write reliable, high-performance Node.js apps.Building on the highly rated third edition, this new edition adds fresh case studies and the latest Node.js developments: newer APIs and libraries, ESM improvements, practical security and production tips, and guidance on using Node.js with TypeScript. It also introduces a new chapter on testing that gives you a full introduction to testing philosophy and practical guidance on writing unit, integration, and end-to-end tests, giving you the confidence to write functional, stable, and reliable code.Real-world, end-to-end examples throughout the book show how to build microservices and distributed systems with Node.js, integrating production-proven technologies such as Redis, RabbitMQ, LevelDB, and ZeroMQ, the same components you’ll find in scalable deployments at companies of all sizes. End-of-chapter exercises consolidate your understanding.By the end of this Node.js book, you’ll have the design patterns, mindset, and hands-on skills every serious Node.js professional needs to confidently architect robust, efficient, and maintainable applications.What you will learnUnderstand Node.js basics and its async event-driven architectureWrite correct async code using callbacks, promises, and async/awaitHarness Node.js streams to create data-driven processing pipelinesImplement trusted software design patterns for production-grade applicationsWrite testable code and automated tests (unit, integration, E2E)Use advanced recipes: caching, batching, async init, offload CPU-bound workBuild and scale microservices and distributed systems powered by Node.jsWho this book is forThis book is for you if you’re a developer or software architect with basic knowledge of JavaScript and Node.js and want to get the most out of these technologies to maximize productivity, design quality, and scalability. It’ll help you level up from junior to senior roles.This book is a tried-and-tested reference guide for readers at all levels. Even those with more experience will find value in the more advanced patterns and techniques presented.You’re expected to have an intermediate understanding of web application development, databases, and software design principles.

Get the best out of Node.js by mastering its most powerful components and patterns to create modular and scalable applications with easeAbout This Book• Create reusable patterns and modules by leveraging the new features of Node.js .• Understand the asynchronous single thread design of node and grasp all its features and patterns to take advantage of various functions.• This unique guide will help you get the most out of Node.js and its ecosystem.Who This Book Is ForThe book is meant for developers and software architects with a basic working knowledge of JavaScript who are interested in acquiring a deeper understanding of how to design and develop enterprise-level Node.js applications.Basic knowledge of Node.js is also helpful to get the most out of this book.What You Will Learn• Design and implement a series of server-side JavaScript patterns so you understand why and when to apply them in different use case scenarios• Become comfortable with writing asynchronous code by leveraging constructs such as callbacks, promises, generators and the async-await syntax• Identify the most important concerns and apply unique tricks to achieve higher scalability and modularity in your Node.js application• Untangle your modules by organizing and connecting them coherently• Reuse well-known techniques to solve common design and coding issues• Explore the latest trends in Universal JavaScript, learn how to write code that runs on both Node.js and the browser and leverage React and its ecosystem to implement universal applicationsIn DetailNode.js is a massively popular software platform that lets you use JavaScript to easily create scalable server-side applications. It allows you to create efficient code, enabling a more sustainable way of writing software made of only one language across the full stack, along with extreme levels of reusability, pragmatism, simplicity, and collaboration. Node.js is revolutionizing the web and the way people and companies create their software.In this book, we will take you on a journey across various ideas and components, and the challenges you would commonly encounter while designing and developing software using the Node.js platform. You will also discover the "Node.js way" of dealing with design and coding decisions.The book kicks off by exploring the basics of Node.js describing it's asynchronous single-threaded architecture and the main design patterns. It then shows you how to master the asynchronous control flow patterns,and the stream component and it culminates into a detailed list of Node.js implementations of the most common design patterns as well as some specific design patterns that are exclusive to the Node.js world.Lastly, it dives into more advanced concepts such as Universal Javascript, and scalability' and it's meant to conclude the journey by giving the reader all the necessary concepts to be able to build an enterprise grade application using Node.js.Style and approachThis book takes its intended readers through a comprehensive explanation to create a scalable and efficient real-time server-side apps.
