# SmartExit - Development Hints

## Logging System

The module uses consolidated logging with a `[smartexit]` prefix:

- **Default behavior**: Logs a single summary line on shutdown
- **Silent mode**: Pass `{ silent: true }` to constructor to disable all logging

### Example output
```
[smartexit] Shutdown complete: killed 3 child processes, ran 2 cleanup functions
```

### Usage
```typescript
// Default - logs summary
const smartExit = new SmartExit();

// Silent - no logging
const smartExit = new SmartExit({ silent: true });
```

## killAll() Return Value

The `killAll()` method returns stats about the cleanup:
```typescript
const { processesKilled, cleanupFunctionsRan } = await smartExit.killAll();
```
