The Shopify Storefront API has been enhanced, allowing store owners to access and manage their entire store and inventory via APIs. This unlocks new use cases for store owners, such as building a Shopify-powered e-commerce site without having a Shopify site, or selling products from any application. The author of the article created a Shopify Gridsome Starter Template using the Storefront API, which can be used as a starting point for building an e-commerce site. The template includes examples of how to retrieve data from the store, manage the shopping cart, and remove items from the cart. The article also discusses thoughts on working with Gridsome and the benefits of using a Shopify-powered backend system.
