Event reference - MercurJS Documentation

The Attribute domain emits events as attributes and their values change. Subscribe to them to run side effects, such as reindexing storefront filters, syncing an external PIM, or kicking off follow-up workflows, instead of polling.

src/subscribers/attribute-created.ts

import type { SubscriberArgs, SubscriberConfig } from "@medusajs/framework"

export default async function attributeCreatedHandler({
  event,
  container,
}: SubscriberArgs<{ id: string }>) {
  const attributeId = event.data.id
  // ...reindex filters, sync to an external system, etc.
}

export const config: SubscriberConfig = {
  event: "product-attribute.created",
}
