PromotionActionConfig

@vendure/core Source

Configuration for all types of PromotionAction.

Signature

interface PromotionActionConfig<T extends ConfigArgs, U extends Array<PromotionCondition<any>> | undefined> extends ConfigurableOperationDefOptions<T> {    priorityValue?: number;    conditions?: U extends undefined ? undefined : ConditionTuple<Exclude<U, undefined>>;    onActivate?: PromotionActionSideEffectFn<T>;    onDeactivate?: PromotionActionSideEffectFn<T>;}

Extends: ConfigurableOperationDefOptions<T>

priorityValue

propertynumber

Default:0

Used to determine the order of application of multiple Promotions on the same Order. See the Promotion priorityScore field for more information.

conditions

propertyU extends undefined ? undefined : ConditionTuple<Exclude<U, undefined>>

Allows PromotionActions to define one or more PromotionConditions as dependencies. Having a PromotionCondition as a dependency has the following consequences:

A Promotion using this PromotionAction is only valid if it also contains all PromotionConditions on which it depends.
The execute() function will receive a statically-typed state argument which will contain the return values of the PromotionConditions' check() function.

onActivate

propertyPromotionActionSideEffectFn<T>v1.8.0Experimental

An optional side effect function which is invoked when the promotion becomes active. It can be used for things like adding a free gift to the order or other side effects that are unrelated to price calculations.

If used, make sure to use the corresponding onDeactivate function to clean up or reverse any side effects as needed.

onDeactivate

propertyPromotionActionSideEffectFn<T>v1.8.0Experimental

Used to reverse or clean up any side effects executed as part of the onActivate function.

PromotionItemActionConfig

@vendure/core Source

Configuration for a PromotionItemAction

Extends: PromotionActionConfig<T, U>

execute

propertyExecutePromotionItemActionFn<T, U>

The function which contains the promotion calculation logic. Should resolve to a number which represents the amount by which to discount the OrderLine, i.e. the number should be negative.

PromotionLineActionConfig

@vendure/core Source

Configuration for a PromotionLineAction

Signature

interface PromotionLineActionConfig<T extends ConfigArgs, U extends PromotionCondition[]> extends PromotionActionConfig<T, U> {    execute: ExecutePromotionLineActionFn<T, U>;}

Extends: PromotionActionConfig<T, U>

execute

propertyExecutePromotionLineActionFn<T, U>

The function which contains the promotion calculation logic. Should resolve to a number which represents the amount by which to discount the OrderLine, i.e. the number should be negative.

PromotionOrderActionConfig

@vendure/core Source

Signature

interface PromotionOrderActionConfig<T extends ConfigArgs, U extends PromotionCondition[]> extends PromotionActionConfig<T, U> {    execute: ExecutePromotionOrderActionFn<T, U>;}

Extends: PromotionActionConfig<T, U>

execute

propertyExecutePromotionOrderActionFn<T, U>

The function which contains the promotion calculation logic. Should resolve to a number which represents the amount by which to discount the Order, i.e. the number should be negative.

PromotionShippingActionConfig

@vendure/core Source

Signature

interface PromotionShippingActionConfig<T extends ConfigArgs, U extends PromotionCondition[]> extends PromotionActionConfig<T, U> {    execute: ExecutePromotionShippingActionFn<T, U>;}

Extends: PromotionActionConfig<T, U>

execute

propertyExecutePromotionShippingActionFn<T, U>

The function which contains the promotion calculation logic. Should resolve to a number which represents the amount by which to discount the Shipping, i.e. the number should be negative.

PromotionLineAction

@vendure/core Source

Represents a PromotionAction which applies to individual OrderLines. The difference from PromotionItemAction is that it applies regardless of the Quantity of the OrderLine.

Example

// Applies a percentage discount to each OrderLineconst linePercentageDiscount = new PromotionLineAction({    code: 'line_percentage_discount',    args: { discount: 'percentage' },    execute(ctx, orderLine, args) {        return -orderLine.linePrice * (args.discount / 100);    },    description: 'Discount every line by { discount }%',});
