Loading Spinners in React with Redux Hooks

When working with React applications, especially those that connect to external APIs, it’s common to encounter the need for loading indicators or spinners. These elements provide a visual cue to users that data is being fetched, improving the user experience significantly. But how do you effectively implement a loading spinner using React Redux Hooks? Let's explore this by addressing a common scenario—showing a spinner while data is being refreshed.

The Problem

Imagine you have a React component that displays event logs. When you click a refresh button, you want to show a loading spinner while the new data is being fetched in the background. This can be achieved using useSelector and useDispatch hooks from react-redux, along with custom actions for showing and hiding the spinner. However, it’s not always straightforward, especially if embracing functional components rather than class-based ones.

Solution: Implementing Spinners with Redux Hooks

To successfully implement a loading spinner, we need to break down the solution into manageable parts. Here’s how to do it:

Step 1: Define Action Creators

We start by defining action creators for showing and hiding the loading spinner in the Redux store.

Step 2: Update the Reducer

Next, we need to adjust the reducer to manage the loading state.

Step 3: Create the React Component

Now we will create a functional component that uses these actions. This component will manage the display of the spinner based on the loading state.

Step 4: Spinner Component

Define a simple spinner component that will be displayed when the loading state is true.

Summary

By using React Redux Hooks, we can effectively manage loading states with a clean, organized approach. We’ve implemented action creators, updated the reducer, and finally created a React component to incorporate everything. This design not only enhances the user experience but also maintains the functional programming paradigm in React.

With this guide, you should be well-equipped to implement loading spinners in your React and Redux applications comfortably. Happy coding!
