PSR-7 middleware for Prophiler

v0.6.0 2017-10-08 11:19 UTC


This package provides a slim PSR-7 middleware implementation based on the zendframework/zend-stratigility package. The middleware is responsible for "adding" the Prophiler Toolbar output to the Response object.

The preferred way of installing bitexpert/prophiler-psr7-middleware is through Composer. Simply add bitexpert/prophiler-psr7-middleware as a dependency:

composer.phar require bitexpert/prophiler-psr7-middleware

How to use the Prophiler PSR7 Middleware

Create the Prophiler toolbar:

    $prophiler = new \Fabfuel\Prophiler\Profiler();
    $toolbar = new \Fabfuel\Prophiler\Toolbar($prophiler);

Set-up your PSR-7 middleware, e.g. by using zendframework/zend-stratigility:

    $request = \Zend\Diactoros\ServerRequestFactory::fromGlobals();
    $response = \Zend\Diactoros\Response();

    $app = new \Zend\Stratigility\MiddlewarePipe();

Add the ProphilerMiddleware to the Middleware pipe:

    $app->pipe(new \bitExpert\Http\Middleware\Psr7\Prophiler\ProphilerMiddleware($toolbar));

"Execute" the Middleware pipe:

    $response = $app($request, $response);

How to add the Prophiler PSR7 Middleware to an Expressive app

Expressive 1.x

Register a pre_routing middleware in config/autoload/middleware-pipeline.local.php:

return [
    'middleware_pipeline' => [[
        'middleware' => bitExpert\Http\Middleware\Psr7\
        'priority' => 11000,

Add a factory definition to config/autoload/

return [
    'dependencies' => [
        'factories' => [
                ProphilerMiddleware::class =>

The \App\Middleware\ProphilerFactory implementation looks like this:

namespace App\Middleware;

use Interop\Container\ContainerInterface;
use Fabfuel\Prophiler\Profiler;
use Fabfuel\Prophiler\Toolbar;
use bitExpert\Http\Middleware\Psr7\Prophiler\ProphilerMiddleware;

class ProphilerFactory
    public function __invoke(ContainerInterface $container)
        $prophiler = new Profiler();
        $toolbar = new Toolbar($prophiler);
        return new ProphilerMiddleware($toolbar);

Expressive 2.x (Programmatic Pipelines)

Adding the following code snippet to the config/pipeline.php file:


$debug = $app->getContainer()->get('config')['debug'] ?? false;
if ($debug) {
   $prophiler  = new \Fabfuel\Prophiler\Profiler();
   $toolbar    = new \Fabfuel\Prophiler\Toolbar($prophiler);
   $middleware = new \bitExpert\Http\Middleware\Psr7\Prophiler\ProphilerMiddleware($toolbar);


Configure Prophiler

By default Prophiler will not log or profile anything. You can add custom benchmarks by adding the following code snippet to the code you want to profile:

$profiler->start('\My\Class::doSomeOtherThing', ['additional' => 'information'], 'My Component');

// here be your custom code


In addition to that Prophiler offers a lot of adapters and decorators for 3rd party tools and libraries.
