2. **Configuration File** (`config/debugbar.php`)
3. **Environment Variables** (in `.env` file)
4. **JobCard Integration** (debug messages and performance timing)

## ⚙️ Configuration

### Environment Variables Added to `.env`:
```env
# Laravel Debugbar Settings
DEBUGBAR_ENABLED=true
DEBUGBAR_HIDE_EMPTY_TABS=true

The following debugging collectors are now active:

- ✅ **Messages** - Custom debug messages
- ✅ **Time** - Performance timing and measurements
- ✅ **Memory** - Memory usage tracking
- ✅ **Exceptions** - Exception and error tracking
- ✅ **Log** - Application log messages
- ✅ **Database** - SQL queries with bindings and timing
- ✅ **Views** - View rendering information
- ✅ **Route** - Current route information

## 🚀 JobCard System Integration

### Debug Features Added:

1. **Component Mount Logging**
   - Logs when JobCard Index component is mounted
   - Shows user information and permissions

2. **Statistics Performance Timing**
   - Measures how long statistics loading takes
   - Shows query execution times

3. **Custom Debug Messages**
   - Statistics data logging
   - Error tracking with context

### Example Debug Code Added:
```php
// In mount() method
if (app()->bound('debugbar')) {
    debugbar()->info('JobCard Index component mounted');
    debugbar()->addMessage('User: ' . auth()->user()->name, 'user');
    debugbar()->addMessage('User permissions checked for JobCard access', 'auth');
}

// In loadStatistics() method
if (app()->bound('debugbar')) {
    debugbar()->startMeasure('statistics', 'Loading JobCard Statistics');
    // ... statistics loading code ...
    debugbar()->stopMeasure('statistics');
    debugbar()->addMessage('Statistics loaded: ' . json_encode($this->statistics), 'statistics');
}
```

## 🌐 How to Use

### 1. Access the Application
```
http://0.0.0.0:8001/job-cards
```

### 2. View the Debugbar
- The debugbar appears at the **bottom of the page** in development mode
- Click on different tabs to see various debugging information
- The bar can be minimized/maximized by clicking the Laravel logo

### 3. Key Debugging Features

#### Database Queries Tab
- See all SQL queries executed
- View query execution times
- Check query bindings and parameters
- Identify slow or N+1 queries

#### Livewire Tab
- Monitor Livewire component lifecycle
- See component property changes
- Track AJAX requests and responses
- Debug component interactions

#### Messages Tab
- View custom debug messages
- See application logs
- Monitor error messages
- Track performance measurements

#### Time Tab
- View page load times
- See individual operation timings
- Identify performance bottlenecks
- Monitor memory usage

### 4. Custom Debug Messages

You can add your own debug messages anywhere in the application:

```php
// Add info message
debugbar()->info('Custom debug message');

// Add message with label
debugbar()->addMessage('Debug data here', 'custom-label');

// Measure performance
debugbar()->startMeasure('operation', 'Description');
// ... your code ...
debugbar()->stopMeasure('operation');

// Add error messages
debugbar()->error('Error occurred');

// Add warnings
debugbar()->warning('Warning message');
```

## 🔒 Security Notes

- Debugbar is **automatically disabled in production** (`APP_ENV=production`)
- Only shows when `APP_DEBUG=true`
- Should only be used in development environments
- Contains sensitive information (queries, session data, etc.)
