What problem does it solve?

Managing complex nested state in SolidJS can lead to broken reactivity and hard-to-maintain code when mutating plain objects directly. This Skill provides a clear, scalable approach to using createStore with path-based updates, lazy signals, and safe utilities like produce, reconcile, unwrap, and createMutable to preserve fine-grained reactivity.

Core Features & Use Cases

• CreateStore for proxy-based nested state with per-property tracking.
• Path-based setters that update only targeted properties, preserving references elsewhere.
• Utilities: produce for transactional mutations, reconcile for API data sync, unwrap for serialization, and createMutable for MobX/Vue-style scenarios.
• Guidance and anti-patterns references to avoid destructive patterns like deep spreads and direct mutation.

Quick Start

Create a store with a nested object and update a path to observe reactive updates.
