Migration Readiness Summary

✅ READY TO START: 2-Day Migration Sprint

Date: $(date) Status: All systems ready for migration Target: Complete PlatformServiceMixin + migrate 52 files

---

🎯 Migration Overview

Goal

Complete the TimeSafari database migration from Dexie to SQLite by:

1. Day 1: Finish PlatformServiceMixin implementation (4-6 hours)
2. Day 2: Migrate all 52 files to PlatformServiceMixin (6-8 hours)

Current Status

• ✅ PlatformServiceMixin: 95% complete (1,301 lines)
• ✅ Migration Tools: Ready and tested
• ✅ Documentation: Complete and cross-machine accessible
• ✅ Tracking System: Automated progress monitoring
• ⚠️ Remaining: 52 files need migration

📊 File Breakdown

Views (42 files) - Priority 1

User-facing components that need immediate attention:

• 25 files from original list
• 17 additional files identified by migration helper

Components (9 files) - Priority 2

Reusable UI components:

• FeedFilters.vue, GiftedDialog.vue, GiftedPrompts.vue
• ImageMethodDialog.vue, OfferDialog.vue, OnboardingDialog.vue
• PhotoDialog.vue, PushNotificationPermission.vue, UserNameDialog.vue

Services (1 file) - Priority 3

Business logic:

• deepLinks.ts

Utils (3 files) - Priority 4

Utility functions:

• util.ts, test/index.ts, PlatformServiceMixin.ts (circular dependency fix)

🛠️ Available Tools

Migration Helper Script

./scripts/migration-helper.sh [command]

Commands: progress, files, patterns, template, validate, next, all

Progress Tracking

• Main Tracker: doc/migration-progress-tracker.md

🔄 Migration Pattern

Standard Template

// 1. Add import
import { PlatformServiceMixin } from "@/utils/PlatformServiceMixin";

// 2. Add to component
export default class ComponentName extends Vue {
  mixins = [PlatformServiceMixin];
  
  // 3. Replace method calls
  async someMethod() {
    // Before: generateInsertStatement(contact, 'contacts')
    // After:  this.$generateInsertStatement(contact, 'contacts')
  }
}

Common Replacements

Old	New
generateInsertStatement	this.$generateInsertStatement
generateUpdateStatement	this.$generateUpdateStatement
parseJsonField	this._parseJsonField
mapColumnsToValues	this._mapColumnsToValues
logToDb	this.$log
logConsoleAndDb	this.$logAndConsole
memoryLogs	this.$memoryLogs

---

🎯 Day 1 Plan: PlatformServiceMixin Completion

Phase 1: Remove Circular Dependency (30 min)

• Remove memoryLogs import from PlatformServiceMixin
• Add self-contained memoryLogs implementation
• Update logger.ts

Phase 2: Add Missing Functions (1 hour)

• Add generateInsertStatement and generateUpdateStatement
• Test both utility functions

Phase 3: Update Types (30 min)

• Add new methods to TypeScript interfaces
• Verify compilation

Phase 4: Testing (1 hour)

• Comprehensive testing and validation
• Ensure no circular dependencies

---

🎯 Day 2 Plan: File Migration

Strategy

1. Views First (42 files) - High impact, user-facing
2. Components (9 files) - Reusable UI elements
3. Services (1 file) - Business logic
4. Utils (3 files) - Utility functions

Batch Processing

• Process similar files together
• Use automated scripts for common patterns
• Validate after each batch

Success Criteria

• 0 files importing databaseUtil
• All tests passing
• No runtime errors
• Performance maintained

---

🚀 Expected Benefits

Immediate Benefits

• 80% reduction in database boilerplate code
• Eliminated circular dependencies
• Centralized caching for performance
• Type-safe database operations

Long-term Benefits

• Simplified testing with mockable mixin
• Consistent error handling across components
• Ready for SQLite-only mode
• Improved maintainability
