🎈 partykit-em (TreeCRDT 🌳)

A proof-of-concept implementation of a tree-based CRDT algorithm with local SQLite database and PartyKit-based backend. Each thoughtspace gets its own room and Turso SQLite database. Real-time collaboration is powered by WebSocket connections through PartyKit, with full history synchronization via HTTP streaming.

Features

• Tree-based CRDT algorithm for conflict-free collaborative editing
• Local SQLite database for offline-first capabilities
• Real-time collaboration via PartyKit WebSocket connections
• Full history synchronization through HTTP streaming
• Separate room and Turso SQLite DB for each thoughtspace
• Foreground sync with all capabilities until local client is fully hydrated

Getting Started

Development

To start the development environment:

yarn dev

This will open two terminal tabs:

• Client development server
• PartyKit development server

You can also run them separately:

# Run the client development server
yarn client:dev

# Run the PartyKit server
yarn server:dev

Other Commands

# Build the client
yarn client:build

# Deploy to PartyKit
yarn deploy

# Seed the database
yarn seed

Project Structure

• src/shared - Shared code between client and server
• src/party/server.ts - PartyKit server implementation
• src/app - Client-side React application
• src/app/worker - Web Workers for database operations
