FAQPage Schema

How do I implement a shopping cart and checkout flow for a product catalog?▼

Shopping cart and checkout flow is implemented by applying cart UI patterns, persistence for item quantities, and checkout orchestration to catalog collections flagged with @catalog. This provides drawer or modal carts with item listings, totals, and checkout call-to-actions.

What's the best way to format currency and manage pricing across cart pages?▼

Currency formatting and pricing across cart pages are managed using the useCurrency and formatPrice utilities. This ensures consistent price presentation and state management for item counts throughout the ecommerce experience.

How does a buy now flow integrate with an existing checkout process?▼

Buy now flow integrates with checkout via the buyNow API, enabling direct purchase transitions. This orchestrates a seamless path from product selection to payment, bypassing the standard cart for immediate transactions.

Do I need an @catalog flag to enable cart functionality in my ecommerce project?▼

Yes, the @catalog flag is required to enable cart functionality. Applicable catalog collections allow items to be added to the cart, with checkout completed using consistent currency handling and loading states.

Can I use drawer and modal UI patterns for shopping cart displays?▼

Drawer and modal UI patterns are supported for shopping cart displays. These patterns include item listing, totals calculation, and checkout CTA presentation, creating a seamless cart experience for catalog-driven projects.
