Product normalizers

Product includes two normalizers:

normalizeProduct: This function is used to map Magento Product into SfProduct, which includes a full product details
normalizeProductCatalogItem: This function is used to map Magento Product into SfProductCatalogItem, which includes only basic product details, needed to display a product in a product catalog

Parameters

`normalizeProduct`

Name	Type	Default value	Description
`context`	`NormalizeProductContext`		Context needed for the normalizer. `sku` is added to specify a product variant
`product`	`ProductWithTypeName` ProductInterface with `__typename`		Magento Product

`normalizeProductCatalogItem`

Name	Type	Default value	Description
`context`	`NormalizerContext`		context needed for the normalizer
`product`	`ProductWithTypeName` ProductInterface with `__typename`		Magento Product

Extending

The SfProduct model is returned from GetProductDetails method. The SfProductCatalogItem model is returned from GetProducts method. If any of these models don't contain the information you need for your Storefront, you can extend its logic using the addCustomFields API. In the following example we extend the normalizeProduct and normalizeProductCatalogItem with countryOfManufacture field which is available on Magento Product.

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

export const unifiedApiExtension = createUnifiedExtension({
  normalizers: {
    addCustomFields: [
      {
        normalizeProduct: (context, product) => {
          const { quantityLimit } = normalizers.normalizeProduct(context, product);
          
          return {
            countryOfManufacture: product.country_of_manufacture,
            isSmallQuantityLimit: quantityLimit && quantityLimit <= 10,
          }
        },
        normalizeProductCatalogItem: (context, product) => ({
          countryOfManufacture: product.country_of_manufacture,
        }),
      },
    ],
  },
  config: {
    ...
  },
});

Source

The normalizeProduct and normalizeProductCatalogItem function consists of several smaller normalizers such as normalizeImage, normalizeRating normalizeDiscountablePrice, and more, which you can override as well.
