CGI::Tiny & Dispatch::Fu - nearly a perfect match

By Brett Estrade on

CGI::Tiny is a very nice, Perlish way to construct CGI scripts these days. It is perfectly suited as a replacement to CGI.pm and is quite at home in a shared hosting environment.

Here's the example from the POD [1] on metacpan:

    use CGI::Tiny;
    cgi {
      my $cgi = $_;
      # set up error handling on $cgi
      # inspect request data via $cgi
      # set response headers if needed via $cgi
      # render response with $cgi->render or $cgi->render_chunk
    };

I recently coupled this with my new module Dispatch::Fu [2], and it worked exceedingly well. It is a darn pleasure to consider from a distance, if I do say so myself:

 
    use CGI::Tiny;
    use Dispatch::Fu;

    cgi {
      my $cgi = $_;
      dispatch {
        my $cgi = shift;
        if (defined $cgi->param('fribble')) {
          return 'fribble';
        }
        return 'default';
      },
      $cgi,
      on fribble => sub { do_fribble($cgi) },
      on default => sub { do_default($cgi) }; #<~semicolon
    };

    sub fribble {
      my $cgi = shift;
      # application/json;charset=UTF-8
      $cgi->render(json         => { msg => 'fribble says hi' });
    }

    sub default {
      # text/html;charset=$charset
      $cgi = $cgi->render(html  => '<html><head>...');
    }

As you may be able to see, this code is able to scale very nicely as different display needs are added.

Enjoy!
