What are some tips for using Suspense in Vue 3?

When using Suspense in Vue 3, consider these tips: 1. Use it for async components to improve loading states. 2. Combine it with defineAsyncComponent for better code splitting. 3. Handle fallback content gracefully to enhance user experience.

Can you explain how to implement a fallback component?

Sure! To implement a fallback component, you can use the fallback prop in the <Suspense> component. For example:

<Suspense fallback={<LoadingSpinner />}> 
  <AsyncComponent /> 
</Suspense>

This will show the LoadingSpinner while the AsyncComponent is loading.

What happens if the async component fails to load?

If the async component fails to load, you can catch the error using the onErrorCaptured lifecycle hook or by providing an error component in the Suspense fallback. This way, you can display a user-friendly error message.

Are there any performance considerations I should keep in mind?

Yes, when using Suspense, be mindful of the number of async components you load simultaneously, as it can impact performance. Also, consider using lazy loading for components that are not immediately needed.
