Image normalizer

The normalizeImage function maps SAP Image into Unified SfImage.

Parameters

Name	Type	Default value	Description
`image`	`Image`		SAP image
`ctx`	`NormalizerContext`		Normalization context including an optional `transformImageUrl` which may transform the url

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 defineNormalizers function.

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

const normalizers = defineNormalizers<typeof normalizersSAP>()({
  ...normalizersSAP,
  normalizeImage: (image, context) => ({
    ...normalizersSAP.normalizeImage(image, context),
    format: image.format,
  }),
});

Source

image.ts

import { maybe } from "@shared/utils";
import { defineNormalizer } from "../defineNormalizer";

export const normalizeImage = defineNormalizer.normalizeImage((image, ctx) => {
  let url = image.url as string;
  if (ctx.transformImageUrl) {
    url = ctx.transformImageUrl(url);
  }

  return {
    alt: maybe(image.altText),
    url,
  };
});
