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.

Using the Redux store middleware

After learning about middleware in general, let's focus more on a specific implementation of the middleware pattern: the Redux store middleware.

While using a similar concept of middleware, Redux middleware solves different problems than, for example, express middleware. It provides a third-party extension point between dispatching an action and the moment it reaches the reducer.

Redux middleware can be used for logging, crash reporting, asynchronous APIs, routing, and much more.

Implementing logging

Let's say we want to log every action that happens in our application together with the new state after the action. Right now, we have already subscribed to the store to log state changes...
