export default function useLocalForge ( key, initialValue = null ) {
	const [storedValue, setStoredValue] = React.useState(initialValue);
	
	React.useEffect(() => {
		(async function () {
			try {
				const value = await localforage.getItem(key);

It seems that if storedValue is an object, this causes a render loop since storedValue is a dependency of the useEffect hook.

I will check it! Thanks!
