in reply to Re: Dancer2 hook
in thread Dancer2 hook

Thanks for the reply. The hook works fine. But it's the implementation that I am having trouble with. By implementation, I mean, putting the hook in a module that I can then use when I want the hook to be applied to errors.

So the code part is real simple: 

hook after_error => sub {
    my $response = shift;
};

The problem is that this code is not catching errors from the application that uses the module. Get it?

      Correct. Here you go: 
      package Dancer2::Plugin::TestHook
use Dancer2;
use Dancer2::Core::Error;

hook after_error => sub {
   my $content = shift;
   $content->{content} .= "hello world";
}

1;

      This hook works fine, but it doesn't get called when I use the module (Dancer::Plugin::TestHook) somewhere else. That's the problem.

        Still incomplete.

        Where is the app that triggers an error?
