    },
    description: 'Discount every item by { discount }%',
});
Signature
class PromotionItemAction<T extends ConfigArgs = ConfigArgs, U extends Array<PromotionCondition<any>> = []> extends PromotionAction<T, U> {

ExecutePromotionItemActionFn​

@vendure/corepromotion-action.ts

Signature
type ExecutePromotionItemActionFn<T extends ConfigArgs, U extends Array<PromotionCondition<any>>> = (
    ctx: RequestContext,
    orderLine: OrderLine,
    args: ConfigArgValues<T>,
    state: ConditionState<U>,
    promotion: Promotion,
) => number | Promise<number>

ExecutePromotionOrderActionFn​

@vendure/corepromotion-action.ts

The function which is used by a PromotionOrderAction to calculate the discount on the Order.

Signature
type ExecutePromotionOrderActionFn<T extends ConfigArgs, U extends Array<PromotionCondition<any>>> = (
    ctx: RequestContext,
    order: Order,
    args: ConfigArgValues<T>,
    state: ConditionState<U>,
    promotion: Promotion,
) => number | Promise<number>

ExecutePromotionShippingActionFn​

@vendure/corepromotion-action.ts

The function which is used by a PromotionOrderAction to calculate the discount on the Order.

Signature
type ExecutePromotionShippingActionFn<T extends ConfigArgs, U extends Array<PromotionCondition<any>>> = (
    ctx: RequestContext,
    shippingLine: ShippingLine,
    order: Order,

PromotionActionSideEffectFn​

@vendure/corepromotion-action.ts
v1.8.0
experimental

The signature of a PromotionAction's side-effect functions onActivate and onDeactivate.

Signature
type PromotionActionSideEffectFn<T extends ConfigArgs> = (
    ctx: RequestContext,
    order: Order,
    args: ConfigArgValues<T>,
    promotion: Promotion,
) => void | Promise<void>

PromotionActionConfig​

@vendure/corepromotion-action.ts

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>;
}

priorityValue​

property
number
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​

property
U 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:

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

onActivate​

property
v1.8.0
experimental
PromotionActionSideEffectFn<T>

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​

property
v1.8.0
experimental
PromotionActionSideEffectFn<T>

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

PromotionItemActionConfig​

Configuration for a PromotionItemAction

Signature
interface PromotionItemActionConfig<T extends ConfigArgs, U extends PromotionCondition[]> extends PromotionActionConfig<T, U> {
    execute: ExecutePromotionItemActionFn<T, U>;
}

execute​

property
ExecutePromotionItemActionFn<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/corepromotion-action.ts
Signature
interface PromotionOrderActionConfig<T extends ConfigArgs, U extends PromotionCondition[]> extends PromotionActionConfig<T, U> {
    execute: ExecutePromotionOrderActionFn<T, U>;
}

execute​

property
ExecutePromotionOrderActionFn<T, U>

    execute: ExecutePromotionShippingActionFn<T, U>;
}

execute​

property
ExecutePromotionShippingActionFn<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.
