Quick Start

// Define your aggregate
class BankAccount extends AggregateRoot
{
    private Money $balance;

    public function deposit(Money $amount): void
    {
        $this->recordThat(new MoneyDeposited($amount));
    }

    protected function applyMoneyDeposited(MoneyDeposited $event): void
    {
        $this->balance = $this->balance->add($event->amount);
    }
}

// Use the event store
$eventStore->save($account);
$history = $eventStore->load($accountId);
