Architecting Angular Applications with Redux, RxJS, and NgRx

Overview of this book

Managing the state of large-scale web applications is a highly challenging task with the need to align different components, backends, and web workers harmoniously. When it comes to Angular, you can use NgRx, which combines the simplicity of Redux with the reactive programming power of RxJS to build your application architecture, making your code elegant and easy to reason about, debug, and test. In this book, we start by looking at the different ways of architecting Angular applications and some of the patterns that are involved in it. This will be followed by a discussion on one-way data flow, the Flux pattern, and the origin of Redux. The book introduces you to declarative programming or, more precisely, functional programming and talks about its advantages. We then move on to the reactive programming paradigm. Reactive programming is a concept heavily used in Angular and is at the core of NgRx. Later, we look at RxJS, as a library and master it. We thoroughly describe how Redux works and how to implement it from scratch. The two last chapters of the book cover everything NgRx has to offer in terms of core functionality and supporting libraries, including how to build a micro implementation of NgRx. This book will empower you to not only use Redux and NgRx to the fullest, but also feel confident in building your own version, should you need it.

Summary

We set out to learn more about basic operators. In doing so, we encountered the map() and filter() operators, which allowed us to control what was being emitted. Knowledge of the do() operator gave us a way to debug our streams. Furthermore, we learned about the existence of sandboxed environments, such as JS Bin and RxFiddle, and how they can help us to quickly get started with RxJS. AJAX was the next topic that we delved into, and we built an understanding of the different scenarios that might occur. Moving on deeper into RxJS, we looked at different operator categories. We barely scratched the surface on that one, but it offered us a way to approach how to learn which types of operators are in the library. Finally, we finished off this chapter by looking at how to change and develop our mindset to thinking about streams.

It is with all this acquired knowledge that...
