VERSION

version 0.08

SYNOPSIS

use Plack::App::Path::Router::PSGI;
use Path::Router;

my $router = Path::Router->new;
$router->add_route('/' =>
    target => sub {
        my $env  = shift;
        [
          200,
          [ 'Content-Type' => 'text/html' ],
          [ '<html><body>Home</body></html>' ]
        ]
    }
);
$router->add_route('/:action/?:id' =>
    validations => {
        id => 'Int'
    },
    target => sub {
        my $env = shift;
        # matches are passed through the $env
        my ($action, $id) = @{ $env->{'plack.router.match.args'} };
        [
          200,
          [ 'Content-Type' => 'text/html' ],
          [ '<html><body>', $action, $id, '</body></html>' ]
        ]
    }
);
$router->add_route('admin/:action/?:id' =>
    validations => {
        id => 'Int'
    },
    # targets are just PSGI apps, so you can
    # wrap with middleware as needed ...
    target => Plack::Middleware::Auth::Basic->wrap(
        sub {
            my $env = shift;
            # matches are passed through the $env
            my ($action, $id) = @{ $env->{'plack.router.match.args'} };
            [
              200,
              [ 'Content-Type' => 'text/html' ],
              [ '<html><body>', $action, $id, '</body></html>' ]
            ]
        },
        authenticator => sub {
            my ($username, $password) = @_;
            return $username eq 'admin' && $password eq 's3cr3t';
        }
    )
);

# now create the Plack app
my $app = Plack::App::Path::Router::PSGI->new( router => $router );

DESCRIPTION

This is a Plack::Component subclass which creates an endpoint to dispatch using Path::Router.

This module is similar to Plack::App::Path::Router except that it expects all the route targets to be pure PSGI apps, nothing more, nothing less. Which means that they will accept a single $env argument and return a valid PSGI formatted response.

This will place, into the $env the router instance into 'plack.router', any valid match in 'plack.router.match' and the collected URL match args in 'plack.router.match.args'.

This thing is dead simple, if my docs don't make sense, then just read the source (all ~45 lines of it).
