title: "What's HTTP::Engine?"

===
title: HTTP::Engine is
list:
 - WSGI on Perl, Rack on Perl
 - Simple
 - Poweful
 - no Pluggable ;-)
 - use Moose;
 - Catalyst::Engine + Cat::Req + Cat::Res
 - + WSGI Power + α

===
title: code
code: |
 use HTTP::Engine;
 my $e = HTTP::Engine->new(
  interface => {
    module => 'ServerSimple',
    args   => { port => 824242 },
    request_handler => \&handler,
  }
 );
 sub handler {
  my $c = shift;
  $c->res->body(Dumper($c->req);
 }

===
title: HTTP::Engine has not
list:
 - Plugin
 - Hook Point
 - WSGI like Middleware

===
title: but
list:
 - WSGI like Middleware layer is
 - HTTP::Engine::Middleware namespace
 - Middleware is uncool naming?
 - give me! cool name!

===
title: HTTP::Engine has
list:
 - HTTP Server Interfaces
 - Request Object Builder
 - Response Manager
 - "MiddleWare's Manager"
 - some moose roles

===
title: Layer
code: |
 +-------------------------------+
 |         Application           |
 +-------------------------------+
 | ↑        Middleware        ↓  |
 +-------------------------------+
 | ↑  Request   |  Response   ↓  |
 | ↑   Builder  |     Writer  ↓  |

===
title: Interface is HTTP Server Driver

===
title: Catalyst::Engine::FastCGI = HTTP::Engine::Interface::FCGI

===
title: Middleware
list:
 - App(Middle(Middle(HTTP::Engine)))
 - using add_around_method_modifier

===
title: code
code: |
 use HTTP::Engine middlewares => [qw(
  DebugScreen
  ModuleReload
 )];
 my $e = HTTP::Engine->new(
  interface => {
    module => 'ServerSimple',
    args   => { port => 824242 },
    request_handler => \&handler,
  }
 );
 sub handler { "snip" }

===
title: very simple

===
title: Middleware functions only by this. 

===
title: Middleware has two hook point
list:
 - wrap
 - wrap is around to request_handler
 - setup
 - setup is Middleware setup phase
 -  for create lazy attributes

===
title: Middleware wrap code 
code: |
 package
  HTTP::Engine::Middleware::ModuleReload;
 use Moose;
 use Module::Reload;
 sub wrap {
     my ($next, $rp, $c) = @_;
     Module::Reload->check;
     $next->($rp, $c);
 }
 1;

===
title: Middleware setup code 1/2
code: |
 package
  HTTP::Engine::Middleware::MobileAttribute;
 use Moose;
 use HTTP::MobileAttribute;
 use HTTP::Engine::Request;

 sub setup {
  my $meta = HTTP::Engine::Request->meta;
  $meta->make_mutable;

===
title: Middleware setup code 2/2
code: |
 #
  $meta->add_attribute(
   mobile_attribute => (
    is => 'ro', isa => 'Object', lazy => 1,
    default => sub {
     my $self = shift;
     $self->{mobile_attribute} =
      HTTP::MobileAttribute
       ->new($self->headers);
    },
  ));
  $meta->make_immutable;
 }1;

===
title: HTTP::Engine want

 - new Interfaces...
 - (Danga::Socket xmpp stomp smtp)
 - ''
 - more Practicable Interfaces
 - (POE Standalone)
 - ''
 - Practicable and Excellent Middlewares
 - ''
 - more Documentation and testing...

===
title: now status
list:

===
title: HTTP::Engine on the future
list:
 - some company use
 -  For instance, sponsor of YAPC::Asia :-)
 - ''
 - replaced from Sledge::Engine
 - replaced from Catalyst::Engine
 - ''
 - and import to Jifty
 -  it works on weekend hackathon, maybe
