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.

Implementing token authentication

After learning why JWT make sense, how tokens look and work, and how to use JWT to authenticate users, we will manually implement token authentication in our Redux application.

The backend server code is provided by this book. You can find the template code for this chapter in (this contains the server and our React/Redux application from the previous chapters).

Unpack the zip file, change into the directory, and run npm install to install the dependencies.

For the sake of simplicity, the JWT tokens that the server generates do not expire, and the secret is set to secret (so that we can use the debugger on to generate valid tokens for testing purposes).

You can change the secret by setting the JWT_SECRET environment variable when starting the server.
