How can I handle errors in Vue 3 with Suspense?

In Vue 3, you can handle errors in Suspense by using the ErrorBoundary component. This allows you to catch errors in your async components.

Can you show me a code example of using ErrorBoundary?

Sure! Here's a simple example:

<template>
  <Suspense>
    <template #default>
      <AsyncComponent />
    </template>
    <template #fallback>
      <LoadingSpinner />
    </template>
  </Suspense>
  <ErrorBoundary>
    <template #default>
      <AsyncComponent />
    </template>
    <template #error="error">
      <div>Error: {{ error.message }}</div>
    </template>
  </ErrorBoundary>
</template>

What happens if the async component fails?

If the async component fails, the ErrorBoundary will catch the error and render the fallback template you provided, allowing you to display an error message.

Is there a way to log these errors for debugging?

Yes, you can log errors in the error slot of the ErrorBoundary. You can use console.error(error) to log the error details.
