How to Show a Loading Spinner for a Minimum Time in React with Axios

When developing a web application, user experience is crucial, and one way to enhance it is by displaying a loading spinner during data fetching operations. However, what happens when your loading spinner disappears almost instantly because your API responds too quickly? In this guide, we will explore how to ensure that a loading spinner is shown for a minimum duration of 2 seconds or even features a nice fade-in effect in your React application using Axios.

The Problem: Quick API Responses

You’ve implemented a loading spinner for your API requests using Axios, but it only shows for a very short time, which may feel abrupt or unprofessional for users. This short display time can create confusion, as users may not even notice that the content is loading.

The initial code snippet looks like this:

In this code, the loading state is set to false as soon as data is fetched from the server. However, this does not consider ensuring a minimum display time for the loader.

The Solution: Implementing Minimum Display Time for the Loader

To tackle the issue of the loading spinner disappearing too quickly, you’ll want to implement a simple yet effective timing mechanism. Here’s how you can achieve it step by step:

Step 1: Introduce a Timer

You need to set a minimum loading time, say x milliseconds (e.g., 2000 milliseconds for 2 seconds). You can use the setTimeout function to delay the loading state from closing.

Step 2: Modify the Loading Logic

You’ll modify the componentDidMount method to include timing logic that displays the loader for a minimum duration.

Here’s an updated version of the Dashboard component:

Step 3: Adjust User Experience

With this code, you ensure that the loading spinner is displayed for at least 2 seconds. The key parts of the logic include:

Capturing the current time when the API request starts.

Calculating the elapsed time after the API responds.

If the time taken by the API is less than the minimum required, you use setTimeout to extend the loading period.

Step 4: Add a Fade-in Effect (Optional)

For additional elegance, you might want to add a fade-in effect to your loader. This can be done using CSS transitions. Add the following CSS to your loader's class:

Then, in your render method, you can toggle the show class based on the loading state, further enhancing the user experience.

Conclusion

Displaying a loading spinner effectively is not just about showing or hiding it; it involves providing a seamless experience for your users. By ensuring that your loading spinner is visible for a minimum duration, you reduce frustration and enhance clarity. Implementing a timer can straightforwardly resolve issues related to fast API responses, ensuring your application feels responsive yet polished.

In summary, remember these key takeaways:

Use setTimeout to ensure your loading spinner is visible for at least a minimum duration.

Calculate elapsed time to dynamically adjust the display duration.

Consider styling for added effects like fading in.

Now, you have the knowledge to implement an effective loading indicator in your React app. Happy coding!
