Displaying loading spinners provides visual feedback during async operations, improving perceived performance in React applications. As the creator of CoreUI with over 11 years of React development experience since 2014, I’ve implemented loading states in countless data-fetching scenarios. The most effective solution is to use state to track loading status and conditionally render spinner components. This approach provides clear feedback and improves user experience during data loading.

Displaying loading states is crucial for providing visual feedback to users during asynchronous operations like API calls or data fetching in React applications. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented loading states in countless production components over 25 years of development. From my expertise, the most effective approach is using useState to track loading status combined with conditional rendering to display appropriate UI. This creates a smooth user experience that keeps users informed about ongoing operations.
