DESCRIPTION In today’s digitally powered world, JavaScript lies at the heart of nearly every web application. From dynamic user interfaces to behind-the-scenes logic, JavaScript enables everything from online shopping to learning new skills and connecting with global communities. This book is your guide to mastering JavaScript through design patterns – proven solutions that make applications scalable, robust, and adaptable to ever-changing demands. This book guides you through the essential world of JavaScript design patterns, beginning by introducing the three main categories of design patterns – creational, structural, and behavioral. Further, readers will learn how to manage asynchronous behavior and integrate them with modern frameworks like React and Vue. Advanced concepts like MVC and MVVM are explained, along with their role in web architecture and scalability. You will learn how to use patterns to enhance unit testing, uncover the process of creating custom patterns, offer insights into common pitfalls and real-world applications used by companies like Google and Airbnb. Whether you are a seasoned developer or just starting your JavaScript journey, by the end of this book, you will be equipped to write cleaner, more efficient JavaScript code, and confidently apply design patterns to solve complex problems. You will have the knowledge to build better web architectures, and understand how to test your code more effectively, positioning you as a competent and skilled JavaScript developer. WHAT YOU WILL LEARN ● Apply core JavaScript design patterns to craft scalable applications. ● Enhance code maintainability with creational, structural, and behavioral patterns. ● Optimize asynchronous operations using throttling, debouncing, and promises. ● Integrate design patterns with modern front-end frameworks like React and Vue. ● Create custom design patterns tailored to unique project requirements. ● Identify and avoid common JavaScript and design pattern implementation pitfalls. ● Understand advanced architectural patterns like MVC, MVP, and MVVM. WHO THIS BOOK IS FOR This book is a perfect guide for JavaScript developers, web architects, and tech enthusiasts looking to optimize code, build scalable applications, and master design patterns. This book is also for testers aiming to improve unit test efficiency. TABLE OF CONTENTS 1. Introduction to JavaScript Design Patterns 2. Creational Design Patterns 3. Structural Design Patterns 4.

Mastering JavaScript Design Patterns
Write reliable code to create powerful applications by mastering advanced JavaScript design patterns About This Book Learn how to use tried and true software design methodologies to enhance your JavaScript code Discover robust JavaScript implementations of classic and advanced design patterns Packed with easy-to-follow examples that can be used to create reusable code and extensible designs Who This Book Is For This book is ideal for JavaScript developers who want to gain expertise in object-oriented programming with JavaScript and the new capabilities of ES-2015 to improve their web development skills and build professional-quality web applications. What You Will Learn Harness the power of patterns for tasks ranging from application building to code testing Rethink and revitalize your code with the use of functional patterns Improve the way you organize your code Build large-scale apps seamlessly with the help of reactive patterns Identify the best use cases for microservices Get to grips with creational, behavioral, and structural design patterns Explore advanced design patterns including dependency injection In Detail With the recent release of ES-2015, there are several new object-oriented features and functions introduced in JavaScript. These new features enhance the capabilities of JavaScript to utilize design patterns and software design methodologies to write powerful code. Through this book, you will explore how design patterns can help you improve and organize your JavaScript code. You'll get to grips with creational, structural and behavioral patterns as you discover how to put them to work in different scenarios. Then, you'll get a deeper look at patterns used in functional programming, as well as model view patterns and patterns to build web applications. This updated edition will also delve into reactive design patterns and microservices as they are a growing phenomenon in the world of web development. You will also find patterns to improve the testability of your code using mock objects, mocking frameworks, and monkey patching. We'll also show you some advanced patterns including dependency injection and live post processing. By the end of the book, you'll be saved of a lot of trial and error and developmental headaches, and you will be on the road to becoming a JavaScript expert. Style and approach Packed with several real-world use cases, this book shows you through step-by-step instructions how to implement the advanced object-oriented programming features to build sophisticated web applications that promote scalability and reusability.

Learn proven patterns, techniques, and tricks to take full advantage of the Node.js platform. Master well-known design principles to create applications that are readable, extensible, and that can grow big. Purchase of the print or Kindle book includes a free eBook in the PDF format. Key Features Learn how to create solid server-side applications by leveraging the full power of Node.js Understand how Node.js works and learn how to take full advantage of its core components as well as the solutions offered by its ecosystem Avoid common mistakes and use proven patterns to create production grade Node.js applications Book DescriptionIn this book, we will show you how to implement a series of best practices and design patterns to help you create efficient and robust Node.js applications with ease. We kick off by exploring the basics of Node.js, analyzing its asynchronous event driven architecture and its fundamental design patterns. We then show you how to build asynchronous control flow patterns with callbacks, promises and async/await. Next, we dive into Node.js streams, unveiling their power and showing you how to use them at their full capacity. Following streams is an analysis of different creational, structural, and behavioral design patterns that take full advantage of JavaScript and Node.js. Lastly, the book dives into more advanced concepts such as Universal JavaScript, scalability and messaging patterns to help you build enterprise-grade distributed applications. Throughout the book, you’ll see Node.js in action with the help of several real-life examples leveraging technologies such as LevelDB, Redis, RabbitMQ, ZeroMQ, and many others. They will be used to demonstrate a pattern or technique, but they will also give you a great introduction to the Node.js ecosystem and its set of solutions.What you will learn Become comfortable with writing asynchronous code by leveraging callbacks, promises, and the async/await syntax Leverage Node.js streams to create data-driven asynchronous processing pipelines Implement well-known software design patterns to create production grade applications Share code between Node.js and the browser and take advantage of full-stack JavaScript Build and scale microservices and distributed systems powered by Node.js Use Node.js in conjunction with other powerful technologies such as Redis, RabbitMQ, ZeroMQ, and LevelDB Who this book is for This book is for developers and software architects who have some prior basic knowledge of JavaScript and Node.js and now want to get the most out of these technologies in terms of productivity, design quality, and scalability. Software professionals with intermediate experience in Node.js and JavaScript will also find valuable the more advanced patterns and techniques presented in this book. This book assumes that you have an intermediate understanding of web application development, databases, and software design principles.
