What are some effective error handling techniques in Svelte?

In Svelte, you can handle errors using try-catch blocks, error stores, and the on:error event. Would you like to know more about any specific technique?

Can you explain how to use try-catch blocks in Svelte?

Sure! You can wrap your code in a try-catch block to catch errors during execution. For example:

try {
  // code that may throw an error
} catch (error) {
  console.error('Error occurred:', error);
}

This helps you manage errors gracefully.

What are error stores and how do they work?

Error stores in Svelte are writable stores that can hold error states. You can create an error store to manage errors across your application, allowing components to reactively respond to errors.

How can I use the on:error event in Svelte?

The on:error event can be used to handle errors in components. For example:

<script>
  let error;
  function handleError(e) {
    error = e;
  }
</script>

<SomeComponent on:error={handleError} />
{#if error}
  <p>Error: {error.message}</p>
{/if}

This allows you to display error messages directly in your UI.
