Features

• Only have one dependency use-sync-external-store which is the shim of react hooks of version v18 useSyncExternalStore.
• It can create multiple stores and is easy to manage stores.
• The shim of useSyncExternalStore support selector to avoid unnecessary rerendering. But it does not support when your react version >=18 and it will use built-in hooks called useSyncExternalStore to implement reactive updates.
