Loading UI with Next.js 13 and React Suspense

Next.js 13 introduces a new way to handle asynchronous data fetching and loading UI with the help of React Suspense. React Suspense allows you to show a loading UI while waiting for data to be fetched. This can greatly improve the user experience by providing immediate feedback to the user that the application is still working and not frozen.

Next.js 13 integrates React Suspense seamlessly, making it easy to implement loading UI for data fetching. With Next.js 13, you can use the new suspense mode to enable React Suspense for data fetching. This allows you to wrap your data fetching components with a Suspense component and show a loading UI while data is being fetched.

Here’s an example of how you can use React Suspense to show a loading UI with Next.js 13:

      
        import React, { Suspense } from 'react';

        function MyComponent() {
          return (
            <Suspense fallback={Loading...}>
              <MyDataFetchingComponent />
            </Suspense>
          );
        }
      
    

In this example, the Suspense component wraps the MyDataFetchingComponent and shows the Loading... message while data is being fetched. Once the data is fetched, the MyDataFetchingComponent will be displayed to the user.

With Next.js 13 and React Suspense, you can easily implement loading UI for data fetching, improving the user experience and providing immediate feedback to the user. This can help make your Next.js applications more responsive and user-friendly.
