Utilities
useLocalStorage, useMediaQuery, useEventCallback, useForkRef, useEventListener and the small helpers the Piplup packages are built on, published on their own.
Nothing here is novel — these are the few functions that kept getting rewritten across the other packages: merging refs, a callback that stays stable without going stale, an effect that doesn't warn during server rendering. They are published separately so you can use them without pulling in anything else.
Package
Worth knowing
useEventCallback keeps a stable function identity while always seeing the latest props and state,
which is what you want for a handler passed into a memoised child or a dependency array.
useLocalStorage is reactive: writing through its helpers updates every hook reading the same key,
including in other tabs, rather than only the component that wrote it.
Two older packages, @piplup/use-event-listener and @piplup/use-local-storage, are deprecated —
both hooks live here now.
