valtio

Valtio is a state management library designed for React applications, making it easy to manage state in a reactive manner. It leverages JavaScript Proxies to allow state objects to become reactive, meaning that changes to the state can automatically trigger updates in the UI without the need for explicit re-renders.

With Valtio, state changes can be triggered from anywhere in your application, which provides greater flexibility in how you manage and manipulate application state. The useSnapshot function creates a local snapshot of the state, ensuring that components only re-render when the specific parts of the state being accessed change, which optimizes rendering performance.

Valtio is compatible with React's Suspense and also offers utility methods for subscribing to state changes, effectively allowing your components to react to state updates easily. This makes it a powerful tool for building complex user interfaces that rely heavily on dynamic state changes.
