# Logger Migration Summary

All console.log/error/warn statements in the backend have been successfully replaced with Winston logger calls.

## Files Updated (7 total)

### 1. `src/server.ts` (1 occurrence removed)
- Removed unused logger import that was added during initial work

### 2. `src/index.ts` (15 occurrences)
- Component: 'Main'
- Replaced all startup, shutdown, and security warning logs
- Improved structured logging with data objects

### 3. `src/websocket.ts` (8 occurrences)
- Component: 'WebSocket'
- Replaced connection, disconnection, error, and message handling logs
- Added correlation IDs for request tracking

### 4. `src/routes/code-review.routes.ts` (8 occurrences)
- Component: 'CodeReview'
- Replaced file verification and job building logs
- Improved debug logging for file operations

### 5. `src/services/analytics.service.ts` (1 occurrence)
- Component: 'Analytics'
- Replaced error logging for KB analytics reading

### 6. `src/services/orchestrator.service.ts` (35 occurrences)
- Component: Inherited from wsLogger ('WebSocket')
- Replaced all chat session, job execution, and client management logs
- Security path validation logs converted to structured format
- Job lifecycle logs with proper context data
- Subtask execution logs with indexes and status

### 7. `src/routes/logging.routes.ts` (5 occurrences)
- Component: 'Logging'
- Replaced frontend log writing, batch, read, and clear operation logs
- Changed frontend log echo from console.log to logger.debug

## Replacement Patterns

| Original | Replacement |
|----------|-------------|
| `console.log()` | `logger.info()` or `logger.debug()` |
| `console.error()` | `logger.error()` with `{ error }` |
| `console.warn()` | `logger.warn()` |

## Logger Components Used

- **Main** - Server startup and lifecycle (`index.ts`)
- **WebSocket** - WebSocket connections and messaging (`websocket.ts`, `orchestrator.service.ts`)
- **CodeReview** - Code review operations (`code-review.routes.ts`)
- **Analytics** - Analytics data operations (`analytics.service.ts`)
- **Logging** - Frontend log handling (`logging.routes.ts`)

## Structured Logging Examples

### Before
```typescript
console.log('[Orchestrator] Job starting:', job.id, job.title);
```

### After
```typescript
wsLogger.info('Job starting', { jobId: job.id, title: job.title });
```

### Before
```typescript
console.error('[Orchestrator] Chat error:', err.message);
```

### After
```typescript
wsLogger.error('Chat error', { error: err });
```

## Benefits

1. **Structured Data** - All logs now include contextual data as objects
2. **File Rotation** - Logs automatically rotate daily (max 14 days, 20MB per file)
3. **Sensitive Data Redaction** - Automatic redaction of passwords, tokens, etc.
4. **Correlation IDs** - Request tracking across log entries
5. **Multiple Transports** - Console (colorized) + file (JSON) + error file
6. **Performance Timing** - Built-in timing utilities for operations
7. **Cross-platform** - Log directory works on Windows/Linux/macOS

## Log Files Location

- **Windows**: `%APPDATA%/@dev-suite/dashboard/logs/`
- **Linux/macOS**: `~/.dev-suite/dashboard/logs/`

Files:
- `combined-YYYY-MM-DD.log` - All log levels
- `error-YYYY-MM-DD.log` - Errors only
- `exceptions-YYYY-MM-DD.log` - Uncaught exceptions
- `rejections-YYYY-MM-DD.log` - Unhandled promise rejections

## Verification

Build successful with no TypeScript errors:
```bash
npm run build
```

No remaining console statements in source code (except documentation/examples):
```bash
grep -r "console\.(log|error|warn)" src/ --include="*.ts" | grep -v logger
```

## Total Console Statements Replaced: 73
