The maximum number of individual items allowed in a single order. This option exists to prevent excessive resource usage when dealing with very large orders. For example, if an order contains a million items, then any operations on that order (modifying a quantity, adding or removing an item) will require Vendure to loop through all million items to perform price calculations against active promotions and taxes. This can have a significant performance impact for very large values.

Attempting to exceed this limit will cause Vendure to throw a {@link OrderItemsLimitError}.

The maximum number of items allowed per order line. This option is an addition on the orderItemsLimit for more granular control. Note orderItemsLimit is still important in order to prevent excessive resource usage.

Attempting to exceed this limit will cause Vendure to throw a {@link OrderItemsLimitError}.

Defines the logic used to calculate the unit price of an OrderItem when adding an item to an Order.

Allows the definition of custom states and transition logic for the order process state machine. Takes an array of objects implementing the CustomOrderProcess interface.

Determines the point of the order process at which stock gets allocated.

Defines the strategy used to merge a guest Order and an existing Order when signing in.

Defines the strategy used to merge a guest Order and an existing Order when signing in as part of the checkout flow.

Allows a user-defined function to create Order codes. This can be useful when integrating with existing systems. By default, Vendure will generate a 16-character alphanumeric string.

Note: when using a custom function for Order codes, bear in mind the database limit for string types (e.g. 255 chars for a varchar field in MySQL), and also the need for codes to be unique.

Defines the strategy used to check if and how an Order may be retrieved via the orderByCode query.

The default strategy permits permanent access to the Customer owning the Order and anyone within 2 hours after placing the Order.

Defines how we handle the situation where an OrderItem exists in an Order, and then later on another is added but in the mean time the price of the ProductVariant has changed.

By default, the latest price will be used. Any price changes resulting from using a newer price will be reflected in the GraphQL OrderLine.unitPrice[WithTax]ChangeSinceAdded field.

Defines the point of the order process at which the Order is set as “placed”.
