Book Description

Building modern web applications that are responsive and resilient is essential in this rapidly evolving digital world. Imagine effortlessly managing complex data streams and creating seamless user experiences—this book helps you do just that by adopting RxJS to boost your development skills and transform your approach to reactive programming.

Written by a seasoned software engineer and consultant with a decade of industry experience, this book equips you to harness the power of RxJS techniques, patterns, and operators tailored for real-world scenarios. Each chapter is filled with practical recipes designed to tackle a variety of challenges, from managing side effects and ensuring error resiliency in client applications to developing real-time chat applications and event-driven microservices. You’ll learn how to integrate RxJS with popular frameworks, such as Angular and NestJS, gaining insights into modern web development practices that enhance performance and interactivity.

By the end of this book, you’ll have mastered reactive programming principles, the RxJS library, and working with Observables, while crafting code that reacts to changes in data and events in a declarative and asynchronous way.

Review

“This is a great guide if you want to get comfortable with reactive concepts using RxJS. I really like how the state management topic is covered. NgRx is a widely adopted solution for state management, but it’s important to understand how we can do it using RxJS, and this book covers that part really well.

Toward the end, the book covers real-time communication using RxJS, where RxJS really shines. It also demonstrates how to effectively use RxJS with NestJS by building microservices.”

Santosh Yadav, Staff Engineer at Celonis, Google Developer Expert for Angular

“RxJS Cookbook is a no-fluff guide for building real-time, responsive web apps. It has over 50 practical recipes which are crucial for understanding RxJS. The book walks you through everything from handling errors and managing state to building PWAs.

The author brings real-world experience to every chapter, offering clear, useful examples that plug right into Angular and NestJS projects. Whether you’re just getting comfortable with RxJS or looking to sharpen your reactive skills, this book will help you write cleaner, more resilient code in less time.”
