What is the order item builder?

The order item builder is run whenever a cart item is transformed into an order item. It builds the order item data from the cart item.

For example, you can add a custom attribute to the order item:

\Aero\Cart\OrderItemBuilder::extend(function (\Aero\Cart\OrderItemBuilder $builder, \Closure $next) {
    $cartItem = $builder->item();

    $builder->setAttributes([
        'acme' => $cartItem->meta->get('acme'),
    ]);

    return $next($builder);
});
