Order normalizer

normalizeOrder: This function is used to map Commercetools Order into SfOrder, which includes order details data.
normalizeOrderListItem: This function maps Commercetools OrderHistory into Unified SfOrderListItem which includes only basic order details, used to display an data in an order list.

Parameters

`normalizeOrder`

Name	Type	Default value	Description
`context`	`NormalizerContext`		Context needed for the normalizer
`input`	`Order`		Commercetools Order

`normalizeOrderListItem`

Name	Type	Default value	Description
`context`	`NormalizerContext`		Context needed for the normalizer
`order`	`Order`		Commercetools Order

`normalizeOrderLineItem`

Name	Type	Default value	Description
`context`	`NormalizerContext`		Context needed for the normalizer
`lineItem`	`LineItem`		Commercetools Line Item

Extending

The SfOrder is returned from the GetOrders Method. If the SfOrder structure doesn't contain the information you need for your Storefront, you can extend its logic using the addCustomFields API. The following example demonstrates how to extend SfOrder with a cartRef field.

export const unifiedApiExtension = createUnifiedExtension({
  normalizers: {
    addCustomFields: [
      {
        normalizeOrder: (context, order) => ({
          cartRef: order.cartRef,
        }),
      },
    ],
  },
  config: {
    ...
  },
});

You can override the normalizeOrder, but it's also available to override the smaller normalizers such as normalizeAddress, normalizeShippingMethod.
