The author has created an Angular template for building Shopify stores using the Storefront API, which allows developers to build e-commerce sites with a single set of serverless functions. The template uses NgRx to manage the state of the cart and products list, and includes features such as product variants, taxes, and shipping calculations. The project is built on top of Netlify Functions, which provides a way to interact with Shopify via GraphQL, and allows developers to use one set of serverless functions across multiple frameworks. The template also includes a demo and is available for download, providing a starting point for building e-commerce sites.
