Learning Redux

By: 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.

Pulling data from an API into the Redux store

Now that we have covered how asynchronous action creators work, it will be easy to pull data from an API into the Redux store.

Extracting boilerplate code

You may have noticed that we are writing a lot of boilerplate code to dispatch the three different actions. We can write a function to be able to reuse this behavior. We will pass an action object, which looks as follows, to this function:

{
types: [ FETCH_POSTS_REQUEST, FETCH_POSTS_SUCCESS, FETCH_POSTS_FAILURE ],
promise: fetch('http://localhost:8080/api/posts')

}

We are now going to write a generic function that contains all the boilerplate code:
