Quick Start
Local Testing
# Initialize local database
npm run db:init:local
# Add test data
wrangler d1 execute telegram-conversations --local \
--command "INSERT INTO users (telegram_id, username) VALUES ('123', 'test')"
# Run migration
wrangler d1 execute telegram-conversations --local \
--file migrations/001_schema_enhancements.sql
# Verify constraints work
wrangler d1 execute telegram-conversations --local \
--command "INSERT INTO user_deposits (user_id, balance) VALUES (999, -1000)"
# Expected: CHECK constraint failed
Production Deployment
⚠️ MANDATORY: Read SCHEMA_MIGRATION_GUIDE.md first
# 1. Backup database
wrangler d1 execute telegram-conversations \
--command ".dump" > backup_$(date +%Y%m%d_%H%M%S).sql
# 2. Run migration
wrangler d1 execute telegram-conversations \
--file migrations/001_schema_enhancements.sql
# 3. Verify success
wrangler d1 execute telegram-conversations \
--command "SELECT 'Migration completed' as status, datetime('now') as timestamp"

Date: 2026-01-19
Changes
- user_deposits: Add
balance >= 0CHECK constraint - deposit_transactions: Add
depositor_namelength <= 50 CHECK constraint - audit_logs: Create new table for operation tracking
Benefits
- Prevent negative balances at database level
- Enforce depositor name length limit
- Track all critical operations for compliance and debugging
- Improved data integrity and auditability
Risk Level
- Low: No breaking changes to application code
- No downtime: Migration completes in < 1 second for typical datasets
- Reversible: Rollback script available
