Last Updated: 2025-07-07 13:27 UTC
Migration Phase: Active Migration (35% complete)

Overview

This document provides detailed checklists for migrating different types of Vue components to use the PlatformServiceMixin pattern. Each checklist ensures the triple migration pattern is properly applied.

🔄 Pre-Migration Checklist

📋 Component Analysis

• Identify component type (View, Component, Dialog)
• List all database operations used
• Identify all notification calls
• Check for raw SQL queries
• Document component dependencies
• Review error handling patterns

🛠️ Preparation

• Backup original component file
• Review similar component migrations for patterns
• Check notification constants availability
• Verify PlatformServiceMixin imports
• Plan migration strategy

📱 View Component Migration Checklist

✅ Database Migration

• Remove databaseUtil imports
• Add PlatformServiceMixin to component mixins
• Replace PlatformServiceFactory.getInstance() with mixin methods
• Update all database operation calls
• Remove unused database-related imports

✅ SQL Abstraction

• Replace raw SQL SELECT with $getContact(), $getAccount(), etc.
• Replace raw SQL INSERT with $addContact(), $addAccount(), etc.
• Replace raw SQL UPDATE with $updateContact(), $updateAccount(), etc.
• Replace raw SQL DELETE with $deleteContact(), $deleteAccount(), etc.
• Remove all raw SQL strings from component
• Verify all database operations use service methods

✅ Notification Migration

• Import createNotifyHelpers from constants
• Replace direct $notify calls with helper methods
• Use notification constants instead of literal strings
• Add missing constants to src/constants/notifications.ts
• Test all notification scenarios
• Remove unused notification imports

✅ Code Quality

• Remove unused imports
• Fix TypeScript errors
• Update component documentation
• Add migration comments where needed
• Run linting and fix issues
• Verify component functionality

🧩 Component Migration Checklist

• Update parent component communication
• Handle component-specific error scenarios

✅ Component-Specific

• Update prop validation
• Review event emissions

• Handle dialog-specific database operations
• Consider modal state management
• Update dialog lifecycle methods

✅ SQL Abstraction

• Apply same SQL abstraction steps as Views
• Handle dialog-specific data operations
• Consider user input validation
• Update dialog result handling

✅ Notification Migration

• Apply same notification migration steps as Views
• Consider dialog context in notifications
• Handle dialog-specific error scenarios
• Update dialog state management

✅ Dialog-Specific

• Update dialog props and events

• Proper memory management
• Acceptable load times

🧪 Testing Checklist

✅ Manual Testing

• Test all component features

• Validate integration points

📊 Migration Documentation Checklist

✅ Update Migration Status

• Update CURRENT_MIGRATION_STATUS.md
• Update migration-time-tracker.md
• Add component to testing tracker
• Update progress percentages
• Document any issues found

✅ Create Testing Guide
