LWR versus Aura store templates and components
Key Takeaway
New B2B stores run on LWR, which supports only Lightning web components. You brand those components with --dxp styling hooks, not your own CSS classes. An Aura store must migrate to LWR before it can use Commerce Subscriptions.
B2B stores are designed in Experience Builder. Each store is built from a template that runs on one of two platforms: the newer Lightning Web Runtime (LWR) or the older Aura platform. The platform decides which components a store can use, how you customize and brand its pages, and which features are available.
Aura and LWR store templates
Starting with Summer '23, all new B2B stores are built on the LWR platform. Some older B2B stores still use the Aura platform. Because of those stores, the Commerce App UI still refers to Aura features and components in some places. If you work in a new LWR store, you can ignore the Aura information.
Salesforce recommends migrating any B2B store built on an older Aura template to an LWR template. When every store runs on LWR, all B2B stores are built with the same technology and the same components.
