v1.0

Initial stable release of FrostState.

FrostState provides small reactive state primitives for values, effects, and keyed stores, with zero runtime dependencies and support for Node, bundlers, and a browser UMD bundle.

Highlights

• Added useState(value) for callable reactive state accessors
• Added useEffect(callback, options) for dependency-tracked reactive effects
• Added StateStore for proxy-backed keyed state
• Added StateStore.wrap(...) and StateStore.merge(...) for object-to-store workflows
• Added browser UMD builds in dist/ exposed as globalThis.State
• Added JSDoc-powered IntelliSense across the public API

Runtime behavior

• useEffect() runs immediately and schedules normal re-runs in a microtask
• effect.sync() is available for immediate re-execution
• StateStore property reads return existing keys and property assignment writes keys
• Missing StateStore property reads return undefined
• Missing keys read during effect tracking subscribe to later assignment without becoming visible keys
• store.set(...) is shallow by default
• Nested reactive stores are available through StateStore.wrap(..., { deep: true }) and StateStore.merge(..., { deep: true })
• API keys such as use, set, has, and keys are reserved

Quality

• Added test coverage for state access, effects, keyed stores, nested store behavior, reserved keys, and effect error handling
• Added CI for lint, test, build, and package validation
• Added npm publish workflow with provenance support

Notes

• The package is ESM-only
• Weak effects rely on WeakRef
