Polaris
Polaris is a single UI framework that makes it simple to integrate with all Shopify surfaces, including Shopify Admin, Checkout, and Customer accounts. Built on web platform standards and web components with consistent and familiar APIs and props, Polaris lets you write highly-performant, HTML-like code that works with any framework. Read more about the new unified Polaris experience on the Shopify developer blog.
