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.

Summary

In this chapter, we discussed why server-rendering makes sense and what benefits we get from using this technique. Then we learned how to implement server-side rendering in our Redux/React application. We did this by using react-router on the server to figure out which page to render. Furthermore, we used ReactDOMServer to render React components to a string. Finally, we discussed how to inject a preloaded Redux store state into our application.

In the upcoming chapters, we will start diving deeper into how Redux works, and cover how to extend Redux. In the next chapter, we will cover how to solve generic problems with higher-order reducers. We will focus on how to make our own abstractions on top of Redux to generalize behavior such as undo/redo. This means that you do not have to re-implement this kind of behavior every time. You can even package these abstractions into...
