How can I handle errors in Vue 3 when using IndexedDB?

In Vue 3, you can handle errors with IndexedDB by using try-catch blocks around your database operations. This allows you to catch any exceptions that occur during transactions.

Can you give me an example of how to implement that?

Sure! Here's a simple example:

try {
  const db = await openDB('my-database', 1);
  await db.put('my-store', data);
} catch (error) {
  console.error('Error occurred:', error);
}

What if I want to show a user-friendly message instead of logging the error?

You can set a state variable to display an error message in your template. For example:

catch (error) {
  this.errorMessage = 'Failed to save data. Please try again.';
}

Is there a way to handle specific error types?

Yes, you can check the error type using instanceof. For example:

if (error instanceof SomeSpecificError) {
  // Handle specific error
}
