We have defined the Product struct in the shared/models/product.go source file to model product data:

package models

type Product struct {
  SKU string
  Name string
  Description string
  ThumbnailPreviewURI string
  ImagePreviewURI string
  Price float64
  Route string
  SummaryDetail string
  Quantity int
}

The SKU field represents the product's stock keeping unit (SKU), a unique id that represents the product. In the sample data set provided, we use incrementing integer values, however, this field is of the string type to accommodate alphanumeric SKUs in the future for extensibility. The Name field represents the name of the product. The Description field represents the short description that will be included in the products listing page. The ThumbnailPreviewURI field provides the path to the thumbnail image of the product. The Price field represents the price of the product and is of the float64 type. The Route field is the server relative path to the product detail page for the given product. The SummaryDetail field represents the long description for the product that will be displayed in the product detail page. Finally, the Quantity field, which is of the int type, is the quantity of the particular product item that is presently in the shopping cart. We will be making use of this field in the next chapter, when we implement the shopping cart functionality.
