Valtio is a small TypeScript state management library that wraps objects in JavaScript proxies, letting you mutate state directly while React components re-render only when accessed properties change. It works with React via useSnapshot and also in vanilla JavaScript applications.

Use cases

• manage react app state with mutable updates
• avoid boilerplate reducers and actions in state management
• optimize react re-renders with fine-grained state subscriptions
• share a global store across react components
• use the same state store in vanilla javascript and react
• build a todo app with simple proxy state

When to choose

• you prefer mutating state directly instead of immutable update patterns
• you want minimal, unopinionated state management with render optimization
• you need shared state in both React and vanilla JS contexts

When to avoid

• you need a batteries-included framework with devtools, middleware, and time travel
• your team relies on strict immutable state conventions
• you need state management outside the JS/React ecosystem
