# Plack::Middleware::Debug::Base(3pm)

Base class for Debug panels

## 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.
