Container Middleware

You can easily integrate your middleware stacks with any PSR container using the Mw\Context\ContainerContext which will allow any middleware to be a container identifier and give you access to your container via the mw context.

<?php

use Krak\Mw;

$container['i'] = 5;
$container['inc_mw'] = function() {
    return function($i, $next) {
        return $next($i + 1);
    };
};

$compose = Mw\composer(Mw\Context\ContainerContext($container), Mw\Link\ContainerLink::class);

$handler = $compose([
    function($i) { return $i; },
    function($i, $next) {
        return $next($i + $next['i']);
    },
    'inc_mw'
]);

assert($handler(4) == 10);
