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.

Core concepts overview

At the core of the Flux pattern is a unidirectional data flow. It uses some core concepts to achieve this flow. The main idea is when an event is created on a UI, through the interaction of a user, an action is created. This action consists of an intent and a payload. The intent is what your are trying to achieve. Think of the intent as a verb. Add an item, remove an item, and so on. The payload is the data change that needs to happen to achieve our intent. If we are trying to add an item, then the payload is the newly created item. The action is then propagated in the flow with the help of a dispatcher. The action and its data eventually end up in a store.

The concepts that make up the Flux pattern are:

  • Action and action creators, where we set up an intention and a payload of data
  • The dispatcher, our spider in the web that is able to send messages left...
