Skill 文档
Valtio makes proxy-state simple for React and vanilla JavaScript. It provides a minimal, flexible, and unopinionated API that turns objects into self-aware proxies, enabling fine-grained subscription and reactivity. Valtio shines at render optimization in React and is compatible with Suspense and React 18+.
The skill is based on Valtio v2.3.0, generated at 2026-01-29.
