# Circular Dependency Analysis
|
|
|
|
## Overview
|
|
|
|
This document analyzes the current state of circular dependencies in the TimeSafari codebase, particularly focusing on the migration from Dexie to SQLite and the PlatformServiceMixin implementation.
|
|
|
|
## Current Circular Dependency Status
|
|
|
|
### ✅ **EXCELLENT NEWS: All Circular Dependencies RESOLVED**
|
|
|
|
The codebase currently has **no active circular dependencies** that are causing runtime or compilation errors. All circular dependency issues have been successfully resolved.
|
|
|
|
### 🔍 **Resolved Dependency Patterns**
|
|
|
|
#### 1. **Logger → PlatformServiceFactory → Logger** (RESOLVED)
|
|
|
|
- **Status**: ✅ **RESOLVED**
|
|
- **Previous Issue**: Logger imported `logToDb` from databaseUtil, which imported logger
|
|
- **Solution**: Logger now uses direct database access via PlatformServiceFactory
|
|
- **Implementation**: Self-contained `logToDatabase()` function in logger.ts
|
|
|
|
#### 2. **PlatformServiceMixin → databaseUtil → logger → PlatformServiceMixin** (RESOLVED)
|
|
|
|
- **Status**: ✅ **RESOLVED**
|
|
- **Previous Issue**: PlatformServiceMixin imported `memoryLogs` from databaseUtil
|
|
- **Solution**: Created self-contained `_memoryLogs` array in PlatformServiceMixin
|
|
- **Implementation**: Self-contained memory logs implementation
|
|
|
|
#### 3. **databaseUtil → logger → PlatformServiceFactory → databaseUtil** (RESOLVED)
|
|
|
|
- **Status**: ✅ **RESOLVED**
|
|
- **Previous Issue**: databaseUtil imported logger, which could create loops
|
|
- **Solution**: Logger is now self-contained and doesn't import from databaseUtil
|
|
|
|
#### 4. **Utility Files → databaseUtil → PlatformServiceMixin** (RESOLVED)
|
|
|
|
- **Status**: ✅ **RESOLVED**
|
|
- **Previous Issue**: `src/libs/util.ts` and `src/services/deepLinks.ts` imported from databaseUtil
|
|
- **Solution**: Replaced with self-contained implementations and PlatformServiceFactory usage
|
|
- **Implementation**:
|
|
- Self-contained `parseJsonField()` and `mapQueryResultToValues()` functions
|
|
- Direct PlatformServiceFactory usage for database operations
|
|
- Console logging instead of databaseUtil logging functions
|
|
|
|
## Detailed Dependency Analysis
|
|
|
|
### ✅ **All Critical Dependencies Resolved**
|
|
|
|
#### PlatformServiceMixin Independence
|
|
|
|
- **Status**: ✅ **COMPLETE**
|
|
- **Achievement**: PlatformServiceMixin has no external dependencies on databaseUtil
|
|
- **Implementation**: Self-contained memory logs and utility functions
|
|
- **Impact**: Enables complete migration of databaseUtil functions to PlatformServiceMixin
|
|
|
|
#### Logger Independence
|
|
|
|
- **Status**: ✅ **COMPLETE**
|
|
- **Achievement**: Logger is completely self-contained
|
|
- **Implementation**: Direct database access via PlatformServiceFactory
|
|
- **Impact**: Eliminates all circular dependency risks
|
|
|
|
#### Utility Files Independence
|
|
|
|
- **Status**: ✅ **COMPLETE**
|
|
- **Achievement**: All utility files no longer depend on databaseUtil
|
|
- **Implementation**: Self-contained functions and direct platform service access
|
|
- **Impact**: Enables complete databaseUtil migration
|
|
|
|
### 🎯 **Migration Readiness Status**

### 🟢 **Healthy Dependencies**
|
|
|
|
#### Logger Usage (80+ files)
