faststore-state-management

To manage client-side state in a React ecommerce storefront, use FastStore SDK hooks like useCart, useSession, and useSearch to handle synchronized cart data, locale, currency, and faceted search interactions. This ensures consistent and validated state across your UI.

The best way to handle cart and session state is by using the @faststore/sdk hooks, which enforces session validation during updates. You should avoid creating custom states that bypass platform validation to maintain data integrity across the storefront.

Implement faceted search interactions and track analytics events by using the useSearch hook from the FastStore SDK. This approach integrates search state management directly with VTEX best practices for analytics event tracking.

Yes, the FastStore SDK supports locale and currency handling for interactive storefronts through the useSession hook. It manages session state to ensure synchronized locale and currency data across the client-side application.

You should avoid custom state implementations for cart data because they bypass platform validation, which leads to inconsistent ecommerce state. Using the useCart hook enforces strict validation and synchronizes cart data reliably across the UI.

You need to use FastStore SDK hooks when building interactive ecommerce storefronts that require synchronized cart data, session validation, locale and currency handling, or faceted search interactions with analytics tracking.
