Plack::Runner.3pm

NAME

Plack::Runner - plackup core

SYNOPSIS

   # Your bootstrap script
   use Plack::Runner;
   my $app = sub { ... };
 
   my $runner = Plack::Runner->new;
   $runner->parse_options(@ARGV);
   $runner->run($app);
 
 

DESCRIPTION

Plack::Runner is the core of plackup runner script. You can create your own frontend to run your application or framework, munge command line options and pass that to "run" method of this class.

"run" method does exactly the same thing as the plackup script does, but one notable addition is that you can pass a PSGI application code reference directly with "--app" option, rather than via ".psgi" file path or with "-e" switch. This would be useful if you want to make an installable PSGI application.

Also, when "-h" or "--help" switch is passed, the usage text is automatically extracted from your own script using Pod::Usage.

NOTES

Do not directly call this module from your ".psgi", since that makes your PSGI application unnecessarily depend on plackup and won't run other backends like Plack::Handler::Apache2 or mod_psgi.

If you really want to make your ".psgi" runnable as a standalone script, you can do this:

   # foo.psgi
   if (__FILE__ eq $0) {
       require Plack::Runner;
       Plack::Runner->run(@ARGV, $0);
   }
 
   # This should always come last
   my $app = sub { ... };
