The common pattern is: a WooCommerce (or other ecommerce platform) backend stays the system of record for products, pricing, cart and orders; a separate frontend — typically built with Next.js and React — renders the storefront and calls the backend through its REST or GraphQL API; and the frontend is deployed to a CDN/edge host for fast page loads. The exact stack (which frontend framework, which APIs, which hosting) is scoped per project, not fixed.
