Valtio uses JavaScript Proxy to make state mutations feel natural (mutate directly, subscribe to changes). No Redux-style actions; just mutate. Used by React/Vue teams preferring mutable state patterns. Competency takes 1 week. Practitioners earn 5-10% premium for cleaner code and faster prototyping.

Apa iku Valtio Proxy State

Valtio is a state management library that uses JavaScript Proxy objects to make state mutations feel natural. Instead of Redux-style actions or Zustand-style setters, you mutate state directly: state.count += 1. Valtio's Proxy intercepts mutations, batches updates, and notifies subscribers (React components re-render). It's minimal (2KB), supports React/Vue, works with TypeScript, and feels more intuitive than immutable state management.

❓ FAQ

Should I use Valtio or Zustand?
Valtio: mutable style (feels imperative), Proxy-based. Zustand: immutable style (feels functional), object-based. Valtio: easier for imperative programmers, smaller bundle. Zustand: easier for functional programmers, more predictable. Both work; choose based on team preference.
How is Valtio different from MobX?
Both use Proxy/observable patterns. Valtio: minimal, 2KB gzipped, for React. MobX: heavier (60KB), broader JS ecosystem, more features. Valtio: simplicity. MobX: power. Use Valtio for React apps; MobX for large cross-framework projects.
Can I mutate state directly?
Yes! That's Valtio's strength. `state.count += 1` triggers re-renders. No dispatchers, no setters. Very intuitive. Proxy intercepts mutations, notifies subscribers.
Does Valtio work with TypeScript?
Yes. Define state shape as type, TypeScript infers mutations. Safe and ergonomic.
How do I debug Valtio state?
Valtio has DevTools. Inspect state snapshots, see mutation history. Browser extension also available. Less mature than Redux DevTools but sufficient.
