Fix worker-only database architecture and Vue Proxy serialization

- Implement worker-only database access to eliminate double migrations
- Add parameter serialization in usePlatformService to prevent Capacitor "object could not be cloned" errors
- Fix infinite logging loop with circuit breaker in databaseUtil
- Use dynamic imports in WebPlatformService to prevent worker thread errors
- Add higher-level database methods (getContacts, getSettings) to composable
- Eliminate Vue Proxy objects through JSON serialization and Object.freeze protection

Resolves Proxy(Array) serialization failures and worker context conflicts across Web/Capacitor/Electron platforms.

# Worker-Only Database Implementation for Web Platform
## Overview
This implementation fixes the double migration issue in the TimeSafari web platform by implementing worker-only database access, similar to the Capacitor platform architecture.
## Problem Solved
**Before:** Web platform had dual database contexts:
- Worker thread: `registerSQLWorker.js``AbsurdSqlDatabaseService.initialize()` → migrations run
- Main thread: `WebPlatformService.dbQuery()``databaseService.query()` → migrations run **AGAIN**
**After:** Single database context:
- Worker thread: Handles ALL database operations and initializes once
- Main thread: Sends messages to worker, no direct database access
## Architecture Changes
### 1. Message-Based Communication
```typescript
// Main Thread (WebPlatformService)
await this.sendWorkerMessage<QueryResult>({
type: "query",
sql: "SELECT * FROM users",
params: []
});
// Worker Thread (registerSQLWorker.js)
onmessage = async (event) => {
const { id, type, sql, params } = event.data;
if (type === "query") {
const result = await databaseService.query(sql, params);
postMessage({ id, type: "success", data: { result } });
}
};
```
### 2. Type-Safe Worker Messages
```typescript
// src/interfaces/worker-messages.ts
export interface QueryRequest extends BaseWorkerMessage {
type: "query";
sql: string;
params?: unknown[];
}
export type WorkerRequest =
| QueryRequest
| ExecRequest
| GetOneRowRequest
| InitRequest
| PingRequest;
```
### 3. Circular Dependency Resolution
**🔥 Critical Fix: Stack Overflow Prevention**
**Problem**: Circular module dependency caused infinite recursion:
- `WebPlatformService` constructor → creates Worker
- Worker loads `registerSQLWorker.js` → imports `databaseService`
- Module resolution creates circular dependency → Stack Overflow
**Solution**: Lazy Loading in Worker
```javascript
// Before (caused stack overflow)
import databaseService from "./services/AbsurdSqlDatabaseService";
// After (fixed)
let databaseService = null;
async function getDatabaseService() {
if (!databaseService) {
// Dynamic import prevents circular dependency
const { default: service } = await import("./services/AbsurdSqlDatabaseService");
databaseService = service;
}
return databaseService;
}
```
**Key Changes for Stack Overflow Fix:**
- ✅ Removed top-level import of database service
- ✅ Added lazy loading with dynamic import
- ✅ Updated all handlers to use `await getDatabaseService()`
- ✅ Removed auto-initialization that triggered immediate loading
- ✅ Database service only loads when first database operation occurs
## Implementation Details
### 1. WebPlatformService Changes
- Removed direct database imports
- Added worker message handling
- Implemented timeout and error handling
- All database methods now proxy to worker
### 2. Worker Thread Changes
- Added message-based operation handling
- Implemented lazy loading for database service
- Added proper error handling and response formatting
- Fixed circular dependency with dynamic imports
### 3. Main Thread Changes
- Removed duplicate worker creation in `main.web.ts`
- WebPlatformService now manages single worker instance
- Added Safari compatibility with `initBackend()`
## Files Modified
1. **src/interfaces/worker-messages.ts** *(NEW)*
- Type definitions for worker communication
- Request and response message interfaces
2. **src/registerSQLWorker.js** *(MAJOR REWRITE)*
- Message-based operation handling
- **Fixed circular dependency with lazy loading**
- Proper error handling and response formatting
3. **src/services/platforms/WebPlatformService.ts** *(MAJOR REWRITE)*
- Worker-only database access
- Message sending and response handling
- Timeout and error management
4. **src/main.web.ts** *(SIMPLIFIED)*
- Removed duplicate worker creation
- Simplified initialization flow
5. **WORKER_ONLY_DATABASE_IMPLEMENTATION.md** *(NEW)*
- Complete documentation of changes
## Benefits
### ✅ Fixes Double Migration Issue
- Database migrations now run only once in worker thread
- No duplicate initialization between main thread and worker
### ✅ Prevents Stack Overflow
- Circular dependency resolved with lazy loading
- Worker loads immediately without triggering database import
- Database service loads on-demand when first operation occurs
### ✅ Improved Performance
- Single database connection
- No redundant operations
- Better resource utilization
### ✅ Better Error Handling
- Centralized error handling in worker
- Type-safe message communication
- Proper timeout handling
### ✅ Consistent Architecture
- Matches Capacitor platform pattern
- Single-threaded database access
- Clear separation of concerns
## Testing Verification
After implementation, you should see:
1. **Worker Loading**:
```
[SQLWorker] Worker loaded, ready to receive messages
```
2. **Database Initialization** (only on first operation):
```
[SQLWorker] Starting database initialization...
[SQLWorker] Database initialization completed successfully
```
3. **No Stack Overflow**: Application starts without infinite recursion
4. **Single Migration Run**: Database migrations execute only once
5. **Functional Database**: All queries, inserts, and updates work correctly
## Migration from Previous Implementation
If upgrading from the dual-context implementation:
1. **Remove Direct Database Imports**: No more `import databaseService` in main thread
2. **Update Database Calls**: Use platform service methods instead of direct database calls
3. **Handle Async Operations**: All database operations are now async message-based
4. **Error Handling**: Update error handling to work with worker responses
## Security Considerations
- Worker thread isolates database operations
- Message validation prevents malformed requests
- Timeout handling prevents hanging operations
- Type safety reduces runtime errors
## Performance Notes
- Initial worker creation has minimal overhead
- Database operations have message passing overhead (negligible)
- Single database connection is more efficient than dual connections
- Lazy loading reduces startup time
## Migration Execution Flow
### Before (Problematic)
```
┌────────────── ───┐ ┌─────────────────┐
│ Main Thread │ │ Worker Thread │
│ │ │ │
│ WebPlatformService│ │registerSQLWorker│
│ ↓ │ │ ↓ │
│ databaseService │ │ databaseService │
│ (Instance A) │ │ (Instance B) │
│ ↓ │ │ ↓ │
│ [Run Migrations] │ │[Run Migrations] │ ← DUPLICATE!
└─────────────── ──┘ └─────────────────┘
```
### After (Fixed)
```
┌─────────────── ──┐ ┌─────────────────┐
│ Main Thread │ │ Worker Thread │
│ │ │ │
│ WebPlatformService │───→│registerSQLWorker│
│ │ │ ↓ │
│ [Send Messages] │ │ databaseService │
│ │ │(Single Instance)│
│ │ │ ↓ │
│ │ │[Run Migrations] │ ← ONCE ONLY!
└─────────────── ──┘ └─────────────────┘
```
## Security Considerations
### 1. **Message Validation**
- All worker messages validated for required fields
- Unknown message types rejected with errors
- Proper error responses prevent information leakage
### 2. **Timeout Protection**
- 30-second timeout prevents hung operations
- Automatic cleanup of pending messages
- Worker health checks via ping/pong
### 3. **Error Sanitization**
- Error messages logged but not exposed raw to main thread
- Stack traces included only in development
- Graceful handling of worker failures
## Testing Considerations
### 1. **Unit Tests Needed**
- Worker message handling
- WebPlatformService worker communication
- Error handling and timeouts
- Migration execution (should run once only)
### 2. **Integration Tests**
- End-to-end database operations
- Worker lifecycle management
- Cross-browser compatibility (especially Safari)
### 3. **Performance Tests**
- Message passing overhead
- Database operation throughput
- Memory usage with worker communication
## Browser Compatibility
### 1. **Modern Browsers**
- Chrome/Edge: Full SharedArrayBuffer support
- Firefox: Full SharedArrayBuffer support (with headers)
- Safari: Uses IndexedDB fallback via `initBackend()`
### 2. **Required Headers**
```
Cross-Origin-Opener-Policy: same-origin
Cross-Origin-Embedder-Policy: require-corp
```
## Deployment Notes
### 1. **Development**
- Enhanced logging shows worker message flow
- Clear separation between worker and main thread logs
- Easy debugging via browser DevTools
### 2. **Production**
- Reduced logging overhead
- Optimized message passing
- Proper error reporting without sensitive data
## Future Enhancements
### 1. **Potential Optimizations**
- Message batching for bulk operations
- Connection pooling simulation
- Persistent worker state management
### 2. **Additional Features**
- Database backup/restore via worker
- Schema introspection commands
- Performance monitoring hooks
## Rollback Plan
If issues arise, rollback involves:
1. Restore original `WebPlatformService.ts`
2. Restore original `registerSQLWorker.js`
3. Restore original `main.web.ts`
4. Remove `worker-messages.ts` interface

* Platform Service Composable for TimeSafari
*
* Provides centralized access to platform-specific services across Vue components.
* This composable encapsulates the singleton pattern and provides a clean interface
* for components to access platform functionality without directly managing
* the PlatformServiceFactory.
*
* Benefits:
* - Centralized service access
* - Better testability with easy mocking
* - Cleaner component code
* - Type safety with TypeScript
* - Reactive capabilities if needed in the future
