Zustand Computed State Middleware

Zustand Computed State is a lightweight, TypeScript-friendly middleware designed for the Zustand state management library. It allows developers to define derived or 'computed' state values that automatically update whenever their base dependencies in the Zustand store change. This eliminates the need for manual re-computation of derived values, simplifying state logic and improving performance by only re-calculating when necessary. The current stable version is 0.2.0, indicating it's in an early but active development phase, with releases likely occurring as features stabilize. Its key differentiator is its straightforward integration into Zustand's middleware chain, providing a clear pattern for computed properties without introducing significant overhead or complex APIs, making it a good choice for applications already leveraging Zustand that require derived state.
