What problem does it solve?

Production-grade shopping cart functionality that ensures session-based persistence, guest support, pre-orders, bundle handling, and automatic cart expiration, reducing checkout friction and lost carts across devices.

• Guest-to-user cart transfer on login, along with pre-order and bundle support to handle complex shopping scenarios.
• Inventory reservation and expiration management to prevent stockouts and stale carts, with robust metadata support for discount codes and notes.
• GraphQL API integration with mutations for add, update, remove, transfer, and metadata updates, enabling flexible frontend integrations.
• Use Case: A user browses as a guest, adds items, later signs in and their guest cart merges into their user cart for a continuous shopping experience.
