NAME

Plack::Middleware::Debug::Base - Base class for Debug panels

SYNOPSIS

  package Plack::Middleware::Debug::YourPanel;
  use parent qw(Plack::Middleware::Debug::Base);

  sub run {
      my($self, $env, $panel) = @_;

      # Do something before the application runs

      return sub {
          my $res = shift;

          # Do something after the application returns

      };
  }

DESCRIPTION

This is the base class for panels.

METHODS

run

This method is called when a request has arrived, before the main application runs. The parameters are $env, the PSGI environment hash reference and $panel, a Plack::Middleware::Debug::Panel object.

If your panel needs to do some response munging, you should return a callback that takes $res the response object. Because you can return a closure, the response filter can also use $env and $panel easily.
