How to Create a Loading Spinner in React: A Step-by-Step Guide

As a beginner in React, you might find yourself wondering how to enhance user experience within your applications. One common feature that can significantly improve how your app interacts with users is a loading spinner. It provides a visual indication that something is happening in the background, making your application feel more responsive and seamless. In this post, we'll walk through the process of creating a loading spinner in React, step by step.

The Problem: Adding a Loading Spinner

When navigating through pages or fetching data, users can sometimes stare at a blank screen. This can be frustrating, making it unclear whether the application is still working or has crashed. By implementing a loading spinner, you can keep users informed of the progress, thereby improving the overall user experience.

Solution: Creating a Loading Spinner in React

Step 1: Create a Loader Component

The first step is to create a separate component for the loading spinner. This allows you to keep your code modular and clean.

Create a new file called Loader.js in your project directory.

Add the following code to define the Loader component:

Step 2: Use the Loader in Your App Component

Next, you will import this loader into your main application component and manage its state.

Open your main App component file.

Import the Loader component you just created:

Set up your component state to manage loading status. Here’s how you can do it:

Step 3: Control the Loading State

In the above example, the loading state is initialized to true, which means when the app first renders, the loader will be displayed. You would typically want to set this to false once your data has loaded or after navigating to a new page.

For example, if you are fetching data from a database, you could set loading to true before the fetch and to false after it completes.
