Learning Redux

By: Daniel Bugl

Overview of this book

The book starts with a short introduction to the principles and the ecosystem of Redux, then moves on to show how to implement the basic elements of Redux and put them together. Afterward, you are going to learn how to integrate Redux with other frameworks, such as React and Angular. Along the way, you are going to develop a blog application. To practice developing growing applications with Redux, we are going to start from nothing and keep adding features to our application throughout the book. You are going to learn how to integrate and use Redux DevTools to debug applications, and access external APIs with Redux. You are also going to get acquainted with writing tests for all elements of a Redux application. Furthermore, we are going to cover important concepts in web development, such as routing, user authentication, and communication with a backend server After explaining how to use Redux and how powerful its ecosystem can be, the book teaches you how to make your own abstractions on top of Redux, such as higher-order reducers and middleware. By the end of the book, you are going to be able to develop and maintain Redux applications with ease. In addition to learning about Redux, you are going be familiar with its ecosystem, and learn a lot about JavaScript itself, including best practices and patterns.

Debugging a Redux Application

In the preceding chapter, we discussed how to combine Redux with Angular. Before that, we focused on how to combine Redux with React.

As you learned, in order to develop a full application, it is not enough to learn Redux, as Redux only deals with the application state. We need to use a separate library/framework to render the user interface and handle interaction with the user. User actions then dispatch actions through action creators, which get processed by reducers. Afterward, the new state is reflected in the user interface by passing it to React or Angular. React and Angular complete the cycle by allowing the user to interact with our Redux application.

Previously, we built a small blog application with React and Redux. In subsequent chapters, we will add more advanced functionalities to our blog application. Before we get to that, however,...
