So far, we have had a look at some operators that will let you create streams or change streams with the map() and filter() operators, we have learned how to manage different AJAX scenarios, and so on. The basics are there, but we haven't really approached the topic of operators in a structured way. What do we mean by that? Well, operators can be thought of as belonging to different categories. The number of operators at our disposal is a staggering 60 plus. It's going to take us time to learn all that, if we ever do. Here is the thing though: we just need to know which different types of operators exist so that we can apply them where appropriate. This reduces our cognitive load and our memory. Once we know which categories we have, we just have to drill down, and most likely we will end up knowing 10-15 operators in total and the rest we can just look...
Architecting Angular Applications with Redux, RxJS, and NgRx
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.
