# @codebelt/classy-store

> Class-based reactive state management for React, Vue, Svelte, Solid, and Angular. Write
> plain TypeScript classes — get fine-grained reactivity, immutable snapshots, and
> zero-boilerplate hooks. ~2.3 KB gzipped. No Providers, no decorators, no reducers.

## Getting Started

- [Introduction & API Reference](https://codebelt.github.io/classy-store/docs/): Full API
  covering `createClassyStore`, `useStore`, `snapshot`, `subscribe`, `shallowEqual`,
  `reactiveMap`, `reactiveSet` (collections entry), and all patterns
- [Tutorial](https://codebelt.github.io/classy-store/docs/TUTORIAL): Step-by-step guide —
  store definition, React hook modes (selector/auto-tracked), collections, inheritance,
  async patterns, local stores

## Utilities

- [Persistence (`persist`)](https://codebelt.github.io/classy-store/docs/PERSIST_TUTORIAL):
  Save state to localStorage/sessionStorage/AsyncStorage with transforms, versioning,
  migration, debounce, cross-tab sync, TTL, and SSR support
- [DevTools (`devtools`)](https://codebelt.github.io/classy-store/docs/DEVTOOLS_TUTORIAL):
  Connect to Redux DevTools for state inspection and time-travel debugging
- [Property Subscriptions (`subscribeKey`)](https://codebelt.github.io/classy-store/docs/SUBSCRIBE_KEY_TUTORIAL):
  Watch a single property with previous/current values
- [Undo/Redo (`withHistory`)](https://codebelt.github.io/classy-store/docs/HISTORY_TUTORIAL):
  Snapshot-based undo/redo with pause/resume and configurable limits

## Architecture

- [Core Architecture](https://codebelt.github.io/classy-store/docs/ARCHITECTURE): Three-layer
  design (write proxy → snapshot → framework hook), computed memoization, structural sharing
- [Persist Architecture](https://codebelt.github.io/classy-store/docs/PERSIST_ARCHITECTURE):
  Save/restore flows, merge strategies, cross-tab sync, storage envelope format
