DESCRIPTION

Mojolicious::Plugin::PlackMiddleware allows you to enable Plack::Middleware inside Mojolicious by wrapping on_proccess so that the portability of your app covers pre/post process too.

It also aimed at those who used to Mojolicious bundle servers. Note that if you can run your application on a plack server, there is proper ways to use middlewares. See http://blog.kraih.com/mojolicious-and-plack.

OPTIONS

This plugin takes an argument in Array reference which contains some middlewares. Each middleware can be followed by callback function for conditional activation, and attributes for middleware.

    my $condition = sub {
        my $c = shift; # Mojolicious controller
        if (...) {
            return 1; # causes the middleware hooked
        }
    };
    plugin plack_middleware => [
        Plack::Middleware::MyMiddleware, $condition, {arg1 => 'some_vale'},
    ];
