deepLinks.ts Pre-Migration Audit

Service Overview

• File: src/services/deepLinks.ts
• Purpose: Deep link handler service for processing and routing deep links in TimeSafari app
• Complexity: Medium (260 lines)
• Migration Priority: High (Services category)

Current State Analysis

Phase 1: Database Migration Assessment

• Status: ⏳ NEEDS MIGRATION
• Issues Found:
  • Uses logConsoleAndDb from ../db/databaseUtil (line 52)
  • 3 instances of logConsoleAndDb usage (lines 175, 237, 246)

Phase 2: SQL Abstraction Assessment

• Status: ✅ NOT NEEDED
• Evidence: No SQL operations found
• Actions Required: None

Phase 3: Notification Migration Assessment

• Status: ✅ NOT NEEDED
• Evidence: No notification usage found
• Actions Required: None

Phase 4: Template Streamlining Assessment

• Status: ✅ NOT NEEDED
• Evidence: No template code found (service file)
• Actions Required: None

Technical Analysis

Database Operations

// Legacy databaseUtil usage
import { logConsoleAndDb } from "../db/databaseUtil";
logConsoleAndDb(`[DeepLink] Invalid route path: ${path}`, true);
logConsoleAndDb("[DeepLink] Processing URL: " + url, false);
logConsoleAndDb("[DeepLink] Error processing deep link:", error);

Code Complexity

• Lines: 260 lines
• Functions: 1 main class (DeepLinkHandler)
• Imports: 4 imports including legacy patterns
• Database Operations: 3 logging calls
• Notification Usage: None

Key Functions Requiring Migration

1. validateAndRoute (line 175): Database migration needed
2. handleDeepLink (line 237, 246): Database migration needed

Migration Plan

Phase 1: Database Migration

1. Replace Legacy Imports

   • Remove logConsoleAndDb import
   • Replace with logger utilities

2. Update Logging Operations

   • Replace logConsoleAndDb calls with logger.error or logger.info
   • Maintain proper tagging: [DeepLink]

Phase 2: SQL Abstraction

1. No Action Required
   • No SQL operations found

Phase 3: Notification Migration

1. No Action Required
   • No notification usage found

Phase 4: Template Streamlining

1. No Action Required
   • No template code found

Estimated Migration Time

• Phase 1: 5-10 minutes
• Phase 2: 0 minutes (not needed)
• Phase 3: 0 minutes (not needed)
• Phase 4: 0 minutes (not needed)
• Total Time: 5-10 minutes

Risk Assessment

• Low Risk: Simple service file with only logging operations
• Breaking Changes: None (logging modernization only)
• Performance Impact: Minimal (enhanced logging)

Success Criteria

• Legacy databaseUtil imports removed
• logConsoleAndDb calls replaced with logger utilities
• Proper logging tags maintained
• Linting passes with no errors
• Service functionality preserved

Migration Notes

• Simple service file requiring minimal migration
• Only logging operations need updating
• No complex database or notification patterns
• Service is critical for deep link handling
