CGI::Application::PSGI

An app using the CGI::Application::PSGI framework needs an app.psgi and requirements.txt file.

In the requirements.txt file, list any module requirements, with at least:

CGI::Application::PSGI
Plack::Builder

In the app.psgi file, the basic code will be something like:

#perl

use lib "lib";

use strict;
use Plack::Builder;
use CGI::Application::PSGI;
use AppCore;

my $handler = sub {
  my $env = shift;
  my $app = AppCore->new({ QUERY => CGI::PSGI->new($env) });
  CGI::Application::PSGI->run($app);
};

builder {
  enable 'Plack::Middleware::ContentLength';
  $handler;
};

In the above example, AppCore.pm is located in the local lib folder and handles processing of the data and the response as per the CGI::Application documentation.

Note

The Plack::Middleware::ContentLength code adds the Content-Length header which is currently required for Perl apps under Stackato.
