What framework does SFRA utilize for building storefronts?

Salesforce Reference Architecture (SFRA) is designed specifically for building modern online storefronts using a JavaScript-based framework. This framework leverages the flexibility and capabilities of JavaScript, allowing developers to create dynamic and responsive user experiences.

By utilizing a JavaScript-based approach, SFRA can take advantage of contemporary web development practices, such as component-based architecture and asynchronous programming, which improve performance and user interaction. This makes it easier for developers to implement rich user interfaces, integrate with APIs, and manage client-side logic efficiently.

The other options do not apply to SFRA. An HTML-only structure would lack the interactivity and functionality required for a sophisticated storefront, rendering it inadequate for modern web applications. A PHP-based framework is not relevant as SFRA is not built on PHP, which is typically used in server-side scripting. Similarly, the ASP.NET framework is associated with a different technology stack and platform that does not align with the architecture of SFRA. Therefore, the use of a JavaScript-based framework is essential for leveraging the full capabilities of SFRA in developing scalable and feature-rich ecommerce sites.
