Promotion Condition

PromotionCondition

PromotionConditions are used to create Promotions. The purpose of a PromotionCondition is to check the order against a particular predicate function (the check function) and to return true if the Order satisfies the condition, or false if it does not.

Signature

class PromotionCondition<T extends ConfigArgs = ConfigArgs, C extends string = string, R extends CheckPromotionConditionResult = any> extends ConfigurableOperationDef<T> {    readonly priorityValue: number;    code: C    constructor(config: PromotionConditionConfig<T, C, R>)    check(ctx: RequestContext, order: Order, args: ConfigArg[], promotion: Promotion) => Promise<R>;}

Extends: ConfigurableOperationDef<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.

code

propertyC

check

method(ctx: RequestContext, order: Order, args: ConfigArg[], promotion: Promotion) => Promise<R>

This is the function which contains the conditional logic to decide whether a Promotion should apply to an Order. See CheckPromotionConditionFn.

CheckPromotionConditionFn

@vendure/core Source

A function which checks whether or not a given Order satisfies the PromotionCondition.

The function should return either a boolean or and plain object type:

false: The condition is not satisfied - do not apply PromotionActions
true: The condition is satisfied, apply PromotionActions
{ [key: string]: any; }: The condition is satisfied, apply PromotionActions and pass this object into the PromotionAction's state argument.

Signature

type CheckPromotionConditionFn<T extends ConfigArgs, R extends CheckPromotionConditionResult> = (    ctx: RequestContext,    order: Order,    args: ConfigArgValues<T>,    promotion: Promotion,) => R | Promise<R>
