Image normalizer

The normalizeImage function maps SFCC Image into Unified SfImage.

Parameters

Name	Type	Default value	Description
`context`	`NormalizerContext`		Context needed for the normalizer.
`image`	`Image`		SFCC image

Extending

The SfImage is returned as a part of multiple models, as for example SfProduct, SfProductCatalogItem, and SfCart. If the SfImage structure doesn't contain the information you need for your Storefront, you can extend its logic using the addCustomFields API.

export const unifiedApiExtension = createUnifiedExtension({
  normalizers: {
    addCustomFields: [
      {
        normalizeImage: (context, image) => ({
          someNewField: "someValue",
        }),
      },
    ],
  },
  config: {
    ...
  },
});
