1. Durable Objects Implementation

Architecture

One Durable Object per ChittyID managing multiple sessions with:

  • Persistent storage (automatic by Cloudflare)
  • WebSocket support for real-time updates
  • Automatic hibernation after 60s inactivity
  • Scheduled cleanup via alarms (hourly)
  • Graceful fallback to KV storage

Key Features

// Session creation
const sessionService = new SessionStateService(env);
const session = await sessionService.createSession(
  chittyId,
  sessionId,
  { metadata: 'value' }
);

// Real-time updates via WebSocket
const ws = await sessionService.connectWebSocket(chittyId, sessionId);
ws.addEventListener('message', (event) => {
  const update = JSON.parse(event.data);
  console.log('Session updated:', update);
});

// Decision tracking
await sessionService.addDecision(chittyId, {
  type: 'contextual_analysis',
  reasoning: 'User requested...',
  confidence: 0.95
});

// Context management
await sessionService.setContext(chittyId, 'theme', 'dark');
const theme = await sessionService.getContext(chittyId, 'theme');

wrangler.toml Configuration

Add to your existing wrangler.toml:

# Durable Objects Configuration
[durable_objects]
classes = [
  { binding = "SESSION_STATE", class_name = "SessionStateDO" }
]

[[durable_objects.bindings]]
name = "SESSION_STATE"
class_name = "SessionStateDO"
script_name = "chittyconnect"

# Migration
[[migrations]]
tag = "v1"
new_classes = ["SessionStateDO"]

# Staging environment
[[env.staging.durable_objects.bindings]]
name = "SESSION_STATE"
class_name = "SessionStateDO"
script_name = "chittyconnect-staging"

# Production environment
[[env.production.durable_objects.bindings]]
name = "SESSION_STATE"
class_name = "SessionStateDO"
script_name = "chittyconnect-production"

Update Worker Entry Point

In src/index.js, export the Durable Object class:

// Import Durable Object
import { SessionStateDO } from './durable-objects/SessionStateDO.js';

// Export for Cloudflare Workers runtime
export { SessionStateDO };

// Your existing exports
export default {
  async fetch(request, env, ctx) {
    // Your existing handler
  }
};

Testing Checklist

  • Session creation successful
  • Session updates persist across requests
  • WebSocket connections establish
  • Hibernation triggers after 60s
  • Alarm cleanup executes hourly
  • KV fallback works when DO unavailable
  • Memory usage < 128MB per DO
  • Concurrent requests handled correctly

Cost Estimate

Free Tier: 1M requests/month, 1GB storage per DO Your Usage: ~500K requests/month Monthly Cost: $0

Specific Q&A

Q: One DO per session or per ChittyID? A: One DO per ChittyID. Benefits:

  • Consistent routing for user's sessions
  • Shared context across sessions
  • Better resource utilization
  • Simpler state management

Q: How to handle global DO location selection? A: Cloudflare automatically selects optimal location based on first request. For optimization:

  • Use location_hint = "enam" for US-based users
  • DOs automatically migrate closer to active users
  • No manual intervention needed

Q: Backup/recovery strategy for DO state? A: Multi-layered:

  • DOs persist automatically to Cloudflare storage
  • Optional hourly backup to D1 via alarm
  • KV fallback for critical operations
  • Export functionality for manual backups
  • Recommended: Daily R2 snapshots

2. R2 Document Storage Implementation

Architecture

Hierarchical R2 storage with D1 metadata indexing:

/chittyid/{chittyId}/evidence/{documentId}
/chittyid/{chittyId}/cases/{documentId}
/chittyid/{chittyId}/attachments/{documentId}
/shared/templates/{documentId}

Key Features

// Document upload
const docService = new DocumentStorageService(env);
const document = await docService.uploadDocument({
  data: fileBuffer,
  chittyId: '01-C-PROD-0001-P-2501-A-X',
  type: 'evidence',
  fileName: 'contract.pdf',
  mimeType: 'application/pdf',
  metadata: { caseId: 'case-123' }
});

// Presigned URL generation
const url = await docService.getPresignedUrl(documentId, chittyId, 3600);
// Returns: https://connect.chitty.cc/api/v1/documents/{id}/download?token=...

// Document search
const results = await docService.searchDocuments(chittyId, 'contract');

// Storage stats
const stats = await docService.getStorageStats(chittyId);
// {totalDocuments: 42, totalSize: 125000000, evidenceCount: 10, ...}

// Multipart upload (>5MB files)
const upload = await docService.createMultipartUpload({
  chittyId, type: 'evidence', fileName: 'large-file.mp4', mimeType: 'video/mp4'
});
await docService.uploadPart(upload.uploadId, 1, chunk1);
await docService.uploadPart(upload.uploadId, 2, chunk2);
await docService.completeMultipartUpload(upload.uploadId, [part1, part2]);

D1 Schema

The migration creates 7 tables:

  1. documents - Core metadata (documentId, chittyId, size, path, etc.)
  2. document_versions - Version history tracking
  3. document_permissions - Sharing and access control
  4. document_tags - Categorization and tagging
  5. document_relationships - Inter-document links
  6. document_access_log - Complete audit trail
  7. storage_quotas - Per-ChittyID usage tracking

Deployment Steps

# 1. Create R2 buckets
wrangler r2 bucket create chittyconnect-documents
wrangler r2 bucket create chittyconnect-documents-staging

# 2. Update wrangler.toml
cat >> wrangler.toml << 'EOF'
[[r2_buckets]]
binding = "DOCUMENT_STORAGE"
bucket_name = "chittyconnect-documents"

[[env.staging.r2_buckets]]
binding = "DOCUMENT_STORAGE"
bucket_name = "chittyconnect-documents-staging"

[[env.production.r2_buckets]]
binding = "DOCUMENT_STORAGE"
bucket_name = "chittyconnect-documents"
EOF

# 3. Run D1 migration
wrangler d1 execute chittyconnect --env staging \
  --file=./migrations/003_document_storage.sql

# Verify tables created
wrangler d1 execute chittyconnect --env staging \
  --command="SELECT name FROM sqlite_master WHERE type='table'"

# 4. Deploy worker
wrangler deploy --env staging

# 5. Test upload
curl -X POST https://connect-staging.chitty.cc/api/v1/documents/upload \
  -H "Authorization: Bearer $TOKEN" \
  -H "X-ChittyID: 01-C-PROD-0001-P-2501-A-X" \
  -F "file=@test-document.pdf" \
  -F "type=evidence"

Testing Checklist

  • Small file upload (<5MB) works
  • Large file multipart upload (>5MB) works
  • Document download succeeds
  • Presigned URLs generate correctly
  • Presigned URLs expire after TTL
  • Document search returns results
  • Storage quotas tracked accurately
  • Document deletion removes from R2 and D1
  • CORS headers present
  • Access logging works

Cost Estimate

Free Tier: 10GB storage, 1M Class A ops, 10M Class B ops Your Usage: ~5GB, 50K uploads/month, 200K downloads/month Monthly Cost: $0

Specific Q&A

Q: How to organize R2 bucket structure? A: Hierarchical by ChittyID:

  • /chittyid/{chittyId}/{type}/{documentId}
  • Enables efficient per-owner listing
  • Supports per-ChittyID quotas
  • Simplifies access control
  • Allows future sharding by ChittyID prefix

Q: Use R2 conditional requests for optimistic locking? A: Yes, for critical documents:

  • Use ETag matching for updates
  • Prevents concurrent modification
  • Store ETags in D1 for validation
  • Example: If-Match: "{etag}" header

Q: Handle large file uploads (multipart)? A: Implemented multipart flow:

  1. createMultipartUpload() - Initialize
  2. uploadPart() - Upload 5MB chunks
  3. completeMultipartUpload() - Finalize
  • Supports files up to 5TB
  • Resume capability via session ID
  • Minimum part size: 5MB (except last)

3. Cloudflare Tunnel + chittysecrets Connect

Cost Estimate

Cloudflare Tunnel: FREE chittysecrets Connect: $8/month (Business plan) Infrastructure Server:

  • Hetzner VPS (2GB): €4.51/month (~$5/month) ✅ Recommended
  • DigitalOcean Droplet (2GB): $12/month
  • AWS t3.small: ~$15/month

Total: $13/month

Specific Q&A

Q: Should chittysecrets Connect run on same server as other infrastructure? A: Separate server recommended for:

  • Security isolation (credentials separate)
  • Independent scaling
  • Failure isolation
  • However, can share if:
    • Cost constraints require it
    • Docker network isolation enforced
    • Regular backups configured

Q: Handle tunnel certificate rotation? A: Automatic by Cloudflare:

  • Tunnel tokens don't expire (unless manually rotated)
  • TLS certificates auto-renew every 90 days
  • No manual intervention needed
  • Recommended: Rotate tunnel token annually for security
    1. Create new tunnel
    2. Update .env
    3. Restart docker-compose
    4. Delete old tunnel

Q: Recommended tunnel replica strategy? A: Single tunnel, multiple cloudflared replicas:

docker-compose up -d --scale cloudflare-tunnel=3

Benefits:

  • Same tunnel token, automatic load balancing
  • Simple configuration
  • Cost-effective For high availability:
  • Create backup tunnel
  • Configure DNS failover
  • Use Cloudflare Load Balancer
