Extending

The SfMoney is returned as a part of multiple models, as for example SfProduct, SfProductCatalogItem, and SfCart. If you want to extend the SfMoney with custom fields, you should use the addCustomFields API.

export const unifiedApiExtension = createUnifiedExtension({
  normalizers: {
    addCustomFields: [
      {
        normalizeMoney: (context, money) => ({
          type: money.type,
        }),
      },
    ],
  },
  config: {
    ...
  },
});

Source

money.ts
import { defineNormalizer } from "../defineNormalizer";

export const normalizeMoney = defineNormalizer.normalizeMoney((context, money) => {
  // Invalid types for BaseMoney - fractionDigits are optional
  const fractionDigits = money.fractionDigits ?? 2;
  const divider = Math.pow(10, fractionDigits);
  const amount = money.centAmount / divider;

  return {
    currency: money.currencyCode,
    amount,
    precisionAmount: amount.toFixed(fractionDigits),
  };
});
