sub BUILD {
  my $plugin = shift;
  my $app    = $plugin->app;

  $plugin->app->add_route(
    method => 'get',
    regexp => qr!/mypagel!,
    code   => \&myfuncl,
  );

Then, in sub myfunc {  I want to call to_json.  Right now, I'm doing a use JSON, and it works properly.  Is there a way to call the serialozer from the app like $app->to_json?  What is recommended?

Thanks,    

Jack
