addFinalProcessor

Register a processor that always runs last (priority 1000) for a given registry value. Only one final processor is allowed per registry key.

Import​

import { addFinalProcessor } from '@evershop/evershop/lib/util/registry';

Syntax​

addFinalProcessor<T>(name: string, callback: SyncProcessor<T> | AsyncProcessor<T>): void

Parameters​

name

Type: string

The name of the registry value to process.

callback

Type: SyncProcessor<T> | AsyncProcessor<T>

The processor function. Receives the current value and must return the transformed value.

Return Value​

Returns void.

Examples​

Override Email Service​

extensions/custom-email/src/bootstrap.ts
import { addFinalProcessor } from '@evershop/evershop/lib/util/registry';

export default function () {
  addFinalProcessor('emailService', (currentService) => {
    return {
      send: async (to, subject, html) => {
        await myCustomProvider.send({ to, subject, html });
      }
    };
  });
}

Notes​

  • Priority is fixed at 1000 (always runs after all other processors)
  • Only one final processor allowed per registry key — throws an error if one already exists
  • Must be registered during bootstrap (before registry is locked)
