Learning Redux

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.

User Authentication

In the preceding chapter, we discussed how to interface with an API to do the following through a backend server:

Fetch posts
Fetch users
Create user accounts (registration)
Create posts

We got one step closer to a fully functional blog application. However, there is still an essential feature missing: login and authentication of users.

After creating a user account, there should be a way to login. Only after being logged in should the user be able to access the New post form. In this chapter, we will remove the username field from the form and instead use authentication to automatically use the currently loggedin user.

In this chapter, we will cover the following topics:

Learning what JSON Web Tokens (JWT) are and how they can be used
Implementing token authentication via JWT in our application
