A sweet combination of Zustand and Valtio
npm install zustand zustand-valtio valtioimport { createWithProxy } from 'zustand-valtio';
const [useCounterState, counterState] = createWithProxy({ count: 0 });
const Counter = () => {
const count = useCounterState((state) => state.count);
const inc = () => ++counterState.count;
return (
<div>
{count} <button onClick={inc}>+1</button>
</div>
);
};Zustand has immer middleware to update state mutably.
Valtio has the same capability. Isn't the combination is sweet?
