Builder for stack middlewares based on HttpKernelInterface.
Stack/Builder is a small library that helps you construct a nested HttpKernelInterface decorator tree. It models it as a stack of middlewares.
If you want to decorate a silex app with session and cache middlewares, you'll have to do something like this:
use Symfony\Component\HttpKernel\HttpCache\Store;
$app = new Silex\Application();
$app->get('/', function () {
return 'Hello World!';
});
$app = new Stack\Session(
new Symfony\Component\HttpKernel\HttpCache\HttpCache(
$app,
new Store(__DIR__.'/cache')
)
);
This can get quite annoying indeed. Stack/Builder simplifies that:
$stack = (new Stack\Builder())
->push('Stack\Session')
->push('Symfony\Component\HttpKernel\HttpCache\HttpCache', new Store(__DIR__.'/cache'));
$app = $stack->resolve($app);
As you can see, by arranging the layers as a stack, they become a lot easier to work with.
In the front controller, you need to serve the request:
use Symfony\Component\HttpFoundation\Request;
$request = Request::createFromGlobals();
$response = $app->handle($request)->send();
$app->terminate($request, $response);
