wishlist-save-for-later

Persist a guest wishlist by implementing a client-side store in localStorage that tracks items with deduplication and addedAt timestamps. This ensures saved items remain reliably accessible across different browsing sessions.

Guest wishlists merge on login by using a utility that POSTs locally stored items to a server endpoint. Following the successful server synchronization, the local storage is cleaned up to prevent data duplication.

Yes, the wishlist system supports sharing named lists with friends and includes optional back-in-stock alerts. It also allows managing multiple named wishlists per user and setting optional expirations for stale entries.

The best way to handle duplicate items in a persistent wishlist is to implement deduplication logic within the client-side guest store. This prevents identical products from being saved multiple times when shoppers add items for later.

Relying on localStorage for wishlist management limits data to a single browser and risks loss if the user clears their cache. You must implement a server endpoint and merge utility to permanently sync guest data upon login.
