NAME

Plack::Client::Backend - turns a Plack::Request into a PSGI app

VERSION

version 0.06

SYNOPSIS

package My::Backend;
use base 'Plack::Client::Backend';

sub app_from_request {
    my $self = shift;
    my ($req) = @_;
    return sub { ... }
}

DESCRIPTION

This is a base class for Plack::Client backends. These backends are handlers for a particular URL scheme, and translate a Plack::Request instance into a PSGI application coderef.

METHODS

new

Creates a new backend instance. Takes no parameters by default, but may be overridden in subclasses.

app_from_request

This method is called with an argument of a Plack::Request object, and should return a PSGI application coderef. The Plack::Request object it receives contains the actual env hash that will be passed to the application, so backends can modify that too, if they need to.

as_code

Returns a coderef which will call "app_from_request" as a method.
