Laravel Debugbar

Installation

Require this package with composer:

composer require barryvdh/laravel-debugbar

After updating composer, add the ServiceProvider to the providers array in config/app.php

If you use a catch-all/fallback route, make sure you load the Debugbar ServiceProvider before your own App ServiceProviders.

Laravel 5.x:

Barryvdh\Debugbar\ServiceProvider::class,

If you want to use the facade to log messages, add this to your facades in app.php:

'Debugbar' => Barryvdh\Debugbar\Facade::class,

The profiler is enabled by default, if you have app.debug=true. You can override that in the config (debugbar.enabled). See more options in config/debugbar.php You can also set in your config if you want to include/exclude the vendor files also (FontAwesome, Highlight.js and jQuery). If you already use them in your site, set it to false. You can also only display the js or css vendors, by setting it to 'js' or 'css'. (Highlight.js requires both css + js, so set to true for syntax highlighting)

Copy the package config to your local config with the publish command:

php artisan vendor:publish --provider="Barryvdh\Debugbar\ServiceProvider"

Lumen:

For Lumen, register a different Provider in bootstrap/app.php:

if (env('APP_DEBUG')) {
 $app->register(Barryvdh\Debugbar\LumenServiceProvider::class);
}

To change the configuration, copy the file to your config folder and enable it:

$app->configure('debugbar');

Usage

You can now add messages using the Facade (when added), using the PSR-3 levels (debug, info, notice, warning, error, critical, alert, emergency):

Debugbar::info($object);
Debugbar::error('Error!');
Debugbar::warning('Watch out…');
Debugbar::addMessage('Another message', 'mylabel');

And start/stop timing:

Debugbar::startMeasure('render','Time for rendering');
Debugbar::stopMeasure('render');
Debugbar::addMeasure('now', LARAVEL_START, microtime(true));
Debugbar::measure('My long operation', function() {
    // Do something…
});

Or log exceptions:

try {
    throw new Exception('foobar');
} catch (Exception $e) {
    Debugbar::addException($e);
}

There are also helper functions available for the most common calls:

// All arguments will be dumped as a debug message
debug($var1, $someString, $intValue, $object);

start_measure('render','Time for rendering');
stop_measure('render');
add_measure('now', LARAVEL_START, microtime(true));
measure('My long operation', function() {
    // Do something…
});

If you want you can add your own DataCollectors, through the Container or the Facade:

Debugbar::addCollector(new DebugBar\DataCollector\MessagesCollector('my_messages'));
//Or via the App container:
$debugbar = App::make('debugbar');
$debugbar->addCollector(new DebugBar\DataCollector\MessagesCollector('my_messages'));

By default, the Debugbar is injected just before </body>. If you want to inject the Debugbar yourself, set the config option 'inject' to false and use the renderer yourself and follow http://phpdebugbar.com/docs/rendering.html

$renderer = Debugbar::getJavascriptRenderer();

Note: Not using the auto-inject, will disable the Request information, because that is added After the response. You can add the default_request datacollector in the config as alternative.

Enabling/Disabling on run time

You can enable or disable the debugbar during run time.

\Debugbar::enable();
\Debugbar::disable();

NB. Once enabled, the collectors are added (and could produce extra overhead), so if you want to use the debugbar in production, disable in the config and only enable when needed.

Twig Integration

Laravel Debugbar comes with two Twig Extensions. These are tested with rcrowe/TwigBridge 0.6.x

Add the following extensions to your TwigBridge config/extensions.php (or register the extensions manually)

'Barryvdh\Debugbar\Twig\Extension\Debug',
'Barryvdh\Debugbar\Twig\Extension\Dump',
'Barryvdh\Debugbar\Twig\Extension\Stopwatch',

The Dump extension will replace the dump function to output variables using the DataFormatter. The Debug extension adds adebug() function which passes variables to the Message Collector, instead of showing it directly in the template. It dumps the arguments, or when empty; all context variables.

{{ debug() }}
{{ debug(user, categories) }}

The Stopwatch extension adds a stopwatch tag similar to the one in Symfony/Silex Twigbridge.

{% stopwatch "foo" %}
    …some things that gets timed
{% endstopwatch %}
