NAME

       Web::Simple::Deployment - various deployment options

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.

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.

Plack-Server
       This works in with exactly the same code as CGI deployment. However instead of letting your web server load script.cgi, you run this on the
       command line:

	 plackup script.cgi

   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;

NAME

       Plack::App::CGIBin - cgi-bin replacement for Plack servers

SYNOPSIS

	 use Plack::App::CGIBin;
	 use Plack::Builder;

	 my $app = Plack::App::CGIBin->new(root => "/path/to/cgi-bin")->to_app;
	 builder {
	     mount "/cgi-bin" => $app;
	 };

	 # Or from the command line
	 plackup -MPlack::App::CGIBin -e 'Plack::App::CGIBin->new(root => "/path/to/cgi-bin")->to_app'

DESCRIPTION

       Plack::App::CGIBin allows you to load CGI scripts from a directory and convert them into a PSGI application.

       This would give you the extreme easiness when you have bunch of old CGI scripts that is loaded using cgi-bin of Apache web server.

HOW IT WORKS

       This application checks if a given file path is a perl script and if so, uses CGI::Compile to compile a CGI script into a sub (like
       ModPerl::Registry) and then run it as a persistent application using CGI::Emulate::PSGI.

       If the given file is not a perl script, it executes the script just like a normal CGI script with fork & exec. This is like a normal web
       server mode and no performance benefit is achieved.

       The default mechanism to determine if a given file is a Perl script is as follows:

       o   Check if the filename ends with ".pl". If yes, it is a Perl script.

       o   Open the file and see if the shebang (first line of the file) contains the word "perl" (like "#!/usr/bin/perl"). If yes, it is a Perl
	   script.

       You can customize this behavior by passing "exec_cb" callback, which takes a file path to its first argument.

       For example, if your perl-based CGI script uses lots of global variables and such and are not ready to run on a persistent environment, you
       can do:

	 my $app = Plack::App::CGIBin->new(
	     root => "/path/to/cgi-bin",
	     exec_cb => sub { 1 },
	 )->to_app;

       to always force the execute option for any files.

       See also Plack::App::WrapCGI if you compile one CGI script into a PSGI application without serving CGI scripts from a directory, to remove
       overhead of filesystem lookups, etc.
