Mastering the React Cache API
summary
React cache API provides a request-scoped singleton that turns repeated database queries into one cached result — demo shows getHunterProfile called by three components triggering three DB queries but after adding cache it runs once and returns to all three. Uses a cache created outside components, requires primitive keys because of reference equality, stores thrown errors as cached responses, and is server-only. Examples include where to export the cache and common pitfalls.
