Implementing a Fallback Component

Let's focus on implementing a fallback component. This step is crucial for enhancing the user experience by providing visual feedback while specific web pages are loading.

React provides the Suspense component for this purpose. The Suspense component allows us to specify a fallback component that is shown while the main content is loading. Here's the syntax for implementing this feature:

  • Line 1: We import the Suspense component from the React library;
  • Lines 5 and 7: We wrap all the app routes with the Suspense component. This enables us to display a fallback component while any route is loaded;
  • Line 5: The Suspense component accepts a fallback prop. In this case, the fallback prop is set to <LoaderComponent />, which specifies the content to be displayed while the main content is loading.
Here is the code from the recording: GitHub

Example

Now, let's integrate a fallback mechanism into our app:

The provided code demonstrates the integration of a fallback mechanism within the App component. Using the Suspense component with a fallback specified as <Loader />, we ensure the visual feedback is displayed while the routes are loading.
