# 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 |
|||

|||
|
|||
### 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()` |
|||
|
|||

## 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 |

* - Centralized service access |

* - Cleaner component code |
|||
* - Type safety with TypeScript |
|||
* - Reactive capabilities if needed in the future |
