## What it is
SyncedStore is a TypeScript library providing an easy-to-use reactive API on top of Yjs CRDTs for building real-time collaborative web applications. It lets developers work with plain JavaScript objects that sync automatically across users and devices, with offline support and conflict resolution built in.

## Use cases
- build a multiplayer todo app that syncs across devices
- add real-time collaboration to a React app
- build an offline-first app that syncs when back online
- collaborative text editing with rich text
- sync shared state between multiple users without a backend conflict logic
- build a collaborative whiteboard or document editor

## When to choose
- you want CRDT-based collaboration with a simple object-oriented API instead of Yjs's lower-level types
- you use React, Vue, or Svelte and want reactive bindings
- you need offline-first sync with automatic conflict resolution
- you want to build local-first, decentralized apps

## When to avoid
- you need a mature, battle-tested solution with a large ecosystem and frequent updates
- you only need simple server-authoritative state sync without offline support
- you need non-JavaScript platforms
- your data model doesn't fit CRDT semantics like counters or strict transactional consistency

## Facets
- artifact type: library
- maturity: active
- function: state-management, serialization, websocket
- domain: web-development, frontend, microservices
- platform: browser, cross-platform
- tags: crdt, yjs, collaborative-editing, offline-first, local-first, reactive-programming, typescript, react, vue, svelte, real-time, nodejs
