LWR versus Aura templates for B2B stores
Key Takeaway
New B2B stores are built on LWR, which supports only Lightning web components. You brand an LWR store with --dxp styling hooks in the Theme panel. Before launch, Salesforce recommends a custom URL on a custom domain served by the Salesforce CDN.
A B2B Commerce store runs on one of two site templates: the newer Lightning Web Runtime (LWR) template or the older Aura template. Aura stores are older stores that are still running. The template decides which components you can use, how you style the store, how you set up its URL and how some checkout settings work.
Which template a store uses
Starting with Summer '23, all new B2B stores are built on the LWR platform. Starting with Winter '24, all new stores are built on enhanced LWR sites. Stores built on LWR before Winter '24 may be on nonenhanced LWR sites.
Some existing B2B stores still use the Aura platform. Parts of the Commerce App UI still refer to Aura features and components. If you work in a new LWR store, you can ignore that Aura information.
Salesforce recommends migrating a B2B store built on an older Aura template to an LWR template. With every store on LWR, you build all your B2B stores with the same technology and components.
