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
`context`	`NormalizerContext`		context needed for the normalizer.
`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 addCustomFields API.

import { normalizers } from "@vsf-enterprise/unified-api-sapcc";

export const unifiedApiExtension = createUnifiedExtension({
  normalizers: {
    addCustomFields: [
      {
        normalizeAttribute: (context, optionQualifier) => {
          const normalizedAttribute = normalizers.normalizeAttribute(context, optionQualifier);
          
          if (normalizedAttribute) {
            return {
              someNewField: "someValue",
            };
          }
          
          return null;
        },
      },
    ],
  },
  config: {
    ...
  },
});
