Debugging Silex applications just got fun

What is the difference between a full-stack framework and a micro framework? To me, this is not about the amount of code, but more about how you build an application and how you structure it. Symfony and Silex share a lot of code (Silex specific code being quite minimal), but developing an application with one or the other is a totally different experience. And choosing between the two really depends on your needs, the application you want to create, the skills of your team, etc...

One of the big advantages of both Symfony and Silex is that they are based on the Symfony HttpKernel component. Why is it an advantage? One of the reasons is the standardization of the HTTP dialog between the client and the application server and the standardization of the HTTP messages via the HttpFoundation component; that makes all applications using it easily interoperable (like Drupal, eZPublish, Laravel, and many others).

But handling HTTP requests with the Symfony HttpKernel also gives you a lot of free and optional features like a built-in reverse proxy written in PHP, easy handling of ESI and Hincludes (via the Fragment sub-framework), or the gorgeous Symfony web profiler:

The timeline panel in the Symfony Web Profiler

I've just published a Silex provider that integrates the Symfony web profiler into Silex.

To get started faster, create a new application via my Silex Skeleton, where the profiler is already integrated and available when in the development environment:

composer create-project fabpot/silex-skeleton somewhere/ 1.0.x-dev
 

Igor recently wrote about HttpKernel and HttpFoundation on his blog... interesting read.

Nice improvement:)

This is really great!

That´s why I love Symfony: Almost all feature can be used everywhere, in a Framework, CMS, CMF, micro-framework, ect.

Oh-My-God, this is just really awesome Fabien, thanks much. As a silex-lover I couldn't expect a greater feature

Awesome

Great addition but unusable for now because of the "minimum-stability": "dev" composer restriction :-/

I currently use components like the HttpFoundation, Event Dispatcher, Dependency Injection Container, ClassLoader in my project. Is it possible to intergrate the web profiler into my project just like the other components?. Thanks for the great work Fabien.

nice, good news, silex is almost like an excuse to read inner code more in depth

coolio

Looks like a great feature! I unfortunately can't get it to work...
I'm getting Twig errors for all Web Profiler templates:

Twig_Error_Loader: Template "@WebProfiler/Profiler/toolbar_js.html.twig" is not defined ().
Twig_Error_Loader: Template "@WebProfiler/Profiler/results.html.twig" is not defined ().

I'm not exactly sure how Twig is supposed to resolve these @WebProfiler templates. I tried fiddling around with Twig settings and installing different dev versions through composer, but that doesn't make any difference. The files are correctly in place at symfony/web-profiler-bundle/... etc.

Do any of you guys have an idea how to solve this?

Kevin Levie, I've got the same error. I have no idea why it's giving me errors.

@Dan, in the end I managed to get the profiler bar to work (for now) by adding this to my Twig initialisation (and making sure the cache was empty):

$webProfilerPath = $dir . '/vendor/symfony/web-profiler-bundle/Symfony/Bundle/WebProfilerBundle/Resources/views';
$app['twig.loader.filesystem']->addPath($webProfilerPath, 'WebProfiler');
