Middleware to insert PHP DebugBar automatically in html responses.



This package is installable and autoloadable via Composer as middlewares/debugbar.

composer require middlewares/debugbar


$dispatcher = new Dispatcher([
	new Middlewares\Debugbar()

$response = $dispatcher->dispatch(new ServerRequest());


You can provide a DebugBar\DebugBar instance to the constructor or an instance of DebugBar\StandardDebugBar will be created automatically. Optionally, you can provide a Psr\Http\Message\ResponseFactoryInterface and Psr\Http\Message\StreamFactoryInterface to create the new responses. If it's not defined, Middleware\Utils\Factory will be used to detect it automatically.

//Create a StandardDebugBar automatically
$debugbar = new Middlewares\Debugbar();

//Use other Debugbar instance
$debugbar = new Middlewares\Debugbar($myDebugbar);

//Use other Debugbar instance and PSR-17 factories
$debugbar = new Middlewares\Debugbar($myDebugbar, $myResponseFactory, $myStreamFactory);


Use this option to capture ajax requests and send the data in the headers. More info about AJAX and Stacked data. By default it's disabled.

$debugbar = (new Middlewares\Debugbar())->captureAjax();


Set true to dump the js/css code inline in the html. This fixes (or mitigate) some issues related with loading the debugbar assets.

$debugbar = (new Middlewares\Debugbar())->inline();


Use this option to pass render options to the debugbar as an array. A list of available options can be found at https://github.com/maximebf/php-debugbar/blob/master/src/DebugBar/JavascriptRenderer.php#L132

An example usage would be to pass a new location for the base_url so that you can rewrite the location of the files needed to render the debug bar. This can be used with symlinks, .htaccess or routes to the files to ensure the debugbar files are accessible.

$debugbar = (new Middlewares\Debugbar())->renderOptions(array('base_url' => "/MyProjectsSubDirectory/maximebf/debugbar/"));
