1. Getting Started

In this section we will learn what Redux is, why it is useful, and most importantly when it is useful. We will also learn how to set up a basic react-redux application.

When to use Redux?

Setting up a React-Redux Application

2. Fundamental Concepts

In this section we will go through the fundamental concepts of Redux that are necessary to understand the workings of a Redux application. We will use code examples to understand the concepts and in the following section we will use them practically.

Store Dispatch Method

Redux Data Flow

3. Redux in Practice

In the previous section we looked at the basic concepts. In this section we use those basic concepts to understand some more complicated concepts and the structure of a Redux application. In the end we will also look at the Counter application to put together all the pieces of our knowledge together.

Redux Application Structure

Modifying the Template for Use

Creating the Redux Store

Creating a Slice

Understanding Slice

Using Selectors to access State

Modifying State by Dispatching Actions

Thunk Functions

Rules for Reducers

Understanding the Counter Application

4. Creating a React-Redux Application

This chapter is focused on practice hence we will utilize the knowledge we acquired in previous sections to create a practical application using Redux along with React.

The Application

Setting Up the Application

Creating the UI Skeleton

Creating the Profile Slice

Creating the Posts Slice

Completing the Posts feature

Displaying Number of Posts and Users

Adding CSS Styling

Creating the UI Skeleton

First, we would want to create a skeleton UI of the application, and then we can create a store, connect the UI to the store, make the app more functional, and add CSS styling. The Main component will create two components, namely, DetailsSection and PostsSection.

In our final product, the DetailsSection and PostsSection will be as follows:

We will create very basic versions of DetailsSection and PostsSection, which we will improve later. The code should be something like this.

With the above code, our app should look like this:

We need the DetailsSection and PostsSection shown in the form of two columns, for that, we will create a grid using CSS. Create a new index.css file in the src folder and write the code for creating a grid inside the #main element.

We can import the CSS files using the JS import statements in index.js:

Now the app should be looking something like this:

Everything was clear?
