Debugbar

The October CMS Debugbar integrates Laravel Debugbar (opens new window) with October CMS. It displays a toolbar at the bottom of every page showing database queries, memory usage, request data, and more. Custom data collectors are included for backend controllers, CMS pages, components, and models.

# Installation

Install the package as a dev dependency using Composer.

composer require october/debugbar --dev

The debugbar is enabled automatically when APP_DEBUG=true in your .env file. You can override this with the DEBUGBAR_ENABLED environment variable.

DEBUGBAR_ENABLED=true

# What You'll See

Once installed, a dark toolbar appears at the bottom of every page (both frontend and backend). It includes tabs for the following.

# October CMS Collectors

In addition to the standard collectors, the following October-specific tabs are included.

# Logging Messages

You can send messages to the debugbar using the debug() helper anywhere in your code.

debug('Hello from the debugbar');
debug($myVariable);

For more control, resolve the debugbar instance directly.

debugbar()->info('Informational message');
debugbar()->warning('Something looks off');
debugbar()->error('Something went wrong');
debugbar()->addMeasure('my-operation', $startTime, $endTime);

In Twig templates, you can use the dump function to inspect variables.

# Configuration

Publish the configuration file to customize collector settings.

php artisan vendor:publish --provider="October\Debugbar\ServiceProvider" --tag=config

Or create config/debugbar.php manually. Common options include enabling or disabling specific collectors.

return [
    'collectors' => [
        'db' => true,       // Database queries
        'views' => false,   // Views with their data
        'events' => false,  // All events fired
        'cache' => false,   // Cache events
    ],

    'options' => [
        'db' => [
            'with_params' => true,  // Show query parameters
            'backtrace' => true,    // Show query origin in code
        ],
    ],
];

# AJAX Debugging

AJAX requests are captured by the debugbar automatically and displayed in the toolbar dropdown. To disable this, set capture_ajax to false in config/debugbar.php.

# Disabling the Debugbar

The debugbar is automatically disabled when APP_DEBUG=false. To explicitly disable it regardless of the debug setting, add the following to your .env file.

DEBUGBAR_ENABLED=false
