Reactive Patterns with RxJS for Angular

Chapter 1: The Power of the Reactive Paradigm

This book is based entirely on useful reactive patterns in Angular applications. Reactive patterns are reusable solutions to a commonly occurring problem using reactive programming. Behind all of these patterns, there is a new way of thinking, new architecture, new coding styles, and new tools.

I know you are impatient to write your first reactive pattern in Angular, but before doing that, and to help you take full advantage of all the RxJS patterns and leverage the reactive paradigm, we will start by explaining, in detail, all the fundamentals. Additionally, we will prepare the groundwork for the following chapters. First, let's start with a basic understanding of the reactive paradigm, its advantages, and the problems it solves. And best of all, let's get into the reactive mindset and start thinking reactively.

We will begin by highlighting the pillars and the advantages of the reactive paradigm. Then, we will describe the relationship between Angular and RxJS. Finally, we will explain the Marble diagram and why it is useful.

Giving an insight into the fundamentals of the reactive paradigm is incredibly important. This will ensure you get the basics right, help you understand the usefulness of the reactive approach, and consequently, help you determine which situation it is best to use it in.

In this chapter, we're going to cover the following topics:

  • Exploring the pillars of reactive programming
  • Using RxJS in Angular and its advantages
  • Learning about the marble diagram – our secret weapon

Key benefits

  • Learn how to write clean, maintainable, performant, and optimized Angular web applications using reactive patterns
  • Explore various RxJS operators and techniques in detail to improve the testing and performance of your code
  • Switch from an imperative mindset to reactive by comparing both

Description

RxJS is a fast, reliable, and compact library for handling asynchronous and event-based programs. It is a first-class citizen in Angular and enables web developers to enhance application performance, code quality, and user experience, so using reactive patterns in your Angular web development projects can improve user interaction on your apps, which will significantly improve the ROI of your applications. This book is a step-by-step guide to learning everything about RxJS and reactivity. You'll begin by understanding the importance of the reactive paradigm and the new features of RxJS 7. Next, you'll discover various reactive patterns, based on real-world use cases, for managing your application’s data efficiently and implementing common features using the fewest lines of code. As you build a complete application progressively throughout the book, you'll learn how to handle your app data reactively and explore different patterns that enhance the user experience and code quality, while also improving the maintainability of Angular apps and the developer's productivity. Finally, you'll test your asynchronous streams and enhance the performance and quality of your applications by following best practices. By the end of this RxJS Angular book, you'll be able to develop Angular applications by implementing reactive patterns.

Who is this book for?

If you're an Angular developer who wants to leverage RxJS for building reactive web applications, this is the book for you. Beginner-level experience with Angular and TypeScript and knowledge of functional programming concepts is assumed.

What you will learn

  • Understand how to use the marble diagram and read it for designing reactive applications
  • Work with the latest features of RxJS 7
  • Build a complete Angular app reactively, from requirement gathering to deploying it

Learning Reactive Patterns is challenging at times. The book is a good read and it goes step by step introducing operators, their syntax, purpose, usage and examples. Then in the later chapters it takes that knowledge and builds on how they can be used in real world scenarios. After going through the examples and use cases, I immediately found some instances in my project at work where I could make improvements. Marble testing was also introduced in a clear and concise way.Must read. Highly recommended.

Im a professional Angular developer with 5 yrs Angular experience and 18 yrs programming. I dont usually buy programming books teaching frameworks or languages anymore. And I already use NG reactive patterns... but this book would have made my journey to understanding them A LOT faster...I feel this is written for the pro. It doesnt waste time. Advanced topics are well explained and sufficiently thorough.
