Backwards compatible shim for React's useSyncExternalStore. Works with any React that supports hooks.
The use-sync-external-store package provides a hook that allows React components to read from an external, synchronous data source and subscribe to updates from that source. It is designed to be a primitive hook for creating other hooks that need to subscribe to external data sources.
Subscribing to an external store
This feature allows you to create a custom hook that subscribes to an external store. The hook will re-render the component whenever the store updates.
import { useSyncExternalStore } from 'use-sync-external-store';
function useCustomHook(store) {
const state = useSyncExternalStore(
store.subscribe,
store.getSnapshot,
store.getServerSnapshot
);
return state;
}
React Redux provides a 'useSelector' hook that allows you to read data from a Redux store and subscribe to updates. It is similar to use-sync-external-store but is specifically tailored for Redux state management.
MobX React Lite offers 'useObserver' and other hooks to reactively work with MobX stores. It provides a way to connect React components to MobX observables, similar to how use-sync-external-store connects components to external stores.
Recoil provides a 'useRecoilValue' hook that subscribes to changes in an atom or selector, which is conceptually similar to use-sync-external-store's ability to subscribe to external data sources.
Zustand is a state management library that offers a hook-based API to subscribe to global state within React components. It is similar to use-sync-external-store in that it allows components to react to external state changes.
