Hi Spatie-Team!

Thank you for the great packages and examples related to event-sourcing!

I assume the lines below does only work if the queue driver is set to sync or if you have a very fast or empty queue, otherwise the account isn't persisted and uuid() will return null. Isn't it?

https://github.com/spatie/larabank-projectors/blob/master/app/Account.php#L18-L34

Can you please show me your preferred way to create an instance.

$uuid will always contain a value, even if you have slow queues.

To know more about event sourcing, consider picking up our upcoming course: https://event-sourcing-laravel.com

How can that be?

If AccountsProjector::onAccountCreated(AccountCreated $event) hasn't handled the event, there we will not be an Account with the given UUID in the database table.

Thank you for the Link to the course. I'm already registered for the newsletter a while.

Ah, you're right, this example assumes that this is being performed in sync
