  - Simpler response handling

- Reduced verbose console logging in CloudflareAdapter
  - Removed debug logs for send/receive operations
  - Kept essential error logging

- Disabled Drawfast tool pending debugging (task-059)

Automerge Integration for TLdraw

This directory contains the Automerge-based sync implementation that replaces the TLdraw sync system.

Files

  • AutomergeToTLStore.ts - Converts Automerge patches to TLdraw store updates
  • TLStoreToAutomerge.ts - Converts TLdraw store changes to Automerge document updates
  • useAutomergeStoreV2.ts - Core React hook for managing Automerge document state with TLdraw
  • useAutomergeSync.ts - Main sync hook that replaces useSync from TLdraw (uses V2 internally)
  • CloudflareAdapter.ts - Adapter for Cloudflare Durable Objects and R2 storage
  • default_store.ts - Default TLdraw store structure for new documents
  • index.ts - Main exports

Benefits over TLdraw Sync

  1. Better Conflict Resolution: Automerge's CRDT nature handles concurrent edits more elegantly
  2. Offline-First: Works seamlessly offline and syncs when reconnected
  3. Smaller Sync Payloads: Only sends changes (patches) rather than full state
  4. Cross-Session Persistence: Better handling of data across different devices/sessions
  5. Automatic Merging: No manual conflict resolution needed

Usage

Replace the TLdraw sync import:

// Old
import { useSync } from "@tldraw/sync"

// New
import { useAutomergeSync } from "@/automerge/useAutomergeSync"

The API is identical, so no other changes are needed in your components.

Cloudflare Integration

The system uses:

  • Durable Objects: For real-time WebSocket connections and document state management
  • R2 Storage: For persistent document storage
  • Automerge Network Adapter: Custom adapter for Cloudflare's infrastructure

Migration

To switch from TLdraw sync to Automerge sync:

  1. Update the Board component to use useAutomergeSync
  2. Deploy the new worker with Automerge Durable Object
  3. The CloudflareAdapter will automatically connect to /connect/{roomId} via WebSocket

The migration is backward compatible - the system will handle both legacy and new document formats.
