=head1 NAME

Web::Simple::Deployment - various deployment options

=head1 DESCRIPTION

This file documents common deployment methods for Web::Simple. If you feel one
is missing, please ask in the IRC channel and we'll work with you to add it.

=head1 CGI

The most basic deployment option is as a CGI script loading and running your
Web::Simple-module:

  #!/usr/bin/env perl

  use Your::Web::Simple::App;
  Your::Web::Simple::App->run_if_script;

Save that as script.cgi and your web server will handle it correctly.

=head2 Self-contained CGI

Sometimes your app is so small that you have only one or two tiny classes that
you want to run as a CGI script. Web::Simple offers a helpful mechanism to
achieve that.

  #!/usr/bin/env perl

  use Web::Simple 'HelloWorld';   # enables strictures and warnings for the file
                                  # additionally, HelloWorld is upgraded to a
                                  # Web::Simple application
  {
    package HelloWorld;

    sub dispatch_request {
      sub (GET) {
        [
          200,
          [ 'Content-type', 'text/plain' ],
          [ 'Hello world! It is a fine ' . HelloWorld::Helper->day ]
        ]
      },
      sub () {
        [ 405, [ 'Content-type', 'text/plain' ], [ 'Method not allowed' ] ]
      }
    }
  }

  {
    package HelloWorld::Helper;

    use DateTime;

    sub day {
      return DateTime->now->day_name;
    }
  }

  HelloWorld->run_if_script;
