Attributes normalizer

Attributes are Unified Data Layer representation of SAP VariantOptionQualifiers. The normalizeAttribute function maps VariantOptionQualifier into a SfAttribute.

Parameters

Name	Type	Default value	Description
`optionQualifier`	`VariantOptionQualifiers`		SAP VariantOptionQualifiers

Extending

The SfAttribute is returned as a part of SfProduct, SfOrder and SfCart. If you want to extend the SfAttribute with custom fields, you should use the defineNormalizers utility.

import { normalizers as normalizersSAP, defineNormalizers } from "@vsf-enterprise/unified-api-sapcc";

const normalizers = defineNormalizers<typeof normalizersSAP>()({
  ...normalizersSAP,
  normalizeAttribute: (optionQualifier, ctx) => {
    const normalizedAttribute = normalizersSAP.normalizeAttribute(optionQualifier, ctx);

    if (normalizedAttribute) {
      return {
        ...normalizedAttribute,
        image: optionQualifier.image,
      };
    }

    return null;
  },
});
