NAME

Plack::App::Path::Router - A Plack component for dispatching with Path::Router

VERSION

version 0.06

SYNOPSIS

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

my $router = Path::Router->new;
$router->add_route('/' =>
    target => sub {
        my ($request) = @_;
        # use the Plack::Request to
        # create a Plack::Response ...
        my $response = $request->new_response( 200 );
        $response->content_type('text/html');
        $response->body('<html><body>HELLO WORLD</body></html>');
    }
);
$router->add_route('/:action/?:id' =>
    validations => {
        id => 'Int'
    },
    target => sub {
        # matches are passed to the target sub ...
        my ($request, $action, $id) = @_;
        # return a PSGI response ...
        [
          200,
          [ 'Content-Type' => 'text/html' ],
          [ '<html><body>', $action, $id, '</body></html>' ]
        ]
    }
);
$router->add_route('/:action/edit/:id' =>
    validations => {
        id => 'Int'
    },
    target => sub {
        my ($r, $action, $id) = @_;
        # return a string (we will wrap
        # it in a PSGI response for you)
        "This is my action($action), and I am editing this id($id)";
    }
);
$router->add_route('/foo' =>
    # target objects are also supported
    # as long as the object responds to
    # the ->execute method
    target => MyApp::Action->new( type => 'FOO' )
);

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

DESCRIPTION

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

This module expects an instance of Path::Router whose routes all have a target that is a CODE ref or an object which responds to the execute method. The CODE ref or execute method will be called when a match is found and passed a Plack::Request instance followed by any path captures that were found. It is expected that the target return one of the following; an object which responds to the finalize method (like Plack::Response), a properly formed PSGI response or a plain string (which we will wrap inside a PSGI response with a status of 200 and a content type of "text/html").

This thing is dead simple, if my docs don't make sense, then just read the source (all ~75 lines of it).

ATTRIBUTES

router

This is a required attribute and must be an instance of Path::Router.

request_class

This is a class name used to create the request object. It defaults to Plack::Request but anything that will accept a PSGI-style $env in the constructor and respond correctly to path_info will work.
