});

  await sendWelcomeEmail({
    to: customer.email,
    name: customer.full_name
  });
}, 10);

Bootstrap Registration​

Register hooks during application bootstrap:

// extensions/notifications/bootstrap.ts
import { hookAfter } from '@evershop/evershop/lib/util/hookable';

export default function bootstrap() {
  hookAfter('insertCustomerData', sendWelcomeEmail, 10);
  hookAfter('createOrder', sendOrderConfirmation, 10);
  hookAfter('createProduct', syncToExternalCatalog, 15);
}

Async Operations​

Hooks support async operations:

import { hookAfter } from '@evershop/evershop/lib/util/hookable';

hookAfter('createOrder', async (order) => {
  // Multiple async operations
  await Promise.all([
    sendEmail(order),
    updateInventory(order),
    createInvoice(order)
  ]);
}, 10);

Notes​

  • Hooks must be registered during bootstrap
