Converting Shopify ID to Nacelle Entry ID

In the process of developing your site you may find that you only have access to a product's Shopify ID, but you'd like to find the product in Nacelle. In these instances you'll need to first convert the Shopify ID into a nacelleEntryId, and then query the Nacelle SDK or API using the nacelleEntryId. 

Here's a function that will convert a Shopify ID into a nacelleEntryID:

function shopifyIdToNacelleEntryId(shopifySubdomain, shopifyId) {
  const base64Encode = (x) =>
    typeof document !== "undefined"
      ? globalThis.btoa(x)
      : Buffer.from(x).toString("base64");

  const nacelleEntryId = base64Encode(
    `id://SHOPIFY/${shopifySubdomain}/default/PRODUCT/${shopifyId}/en-US`
  );

  console.log(nacelleEntryId);
}
