Valtio Proxy State
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.
Valtio Proxy Stateとは
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.
