NAME

CatalystX::Errors - Standard error handling with content negotiation

SYNOPSIS

Use in your application class

    package Example;

    use Catalyst;

    __PACKAGE__->setup_plugins([qw/Errors/]);
    __PACKAGE__->setup();
    __PACKAGE__->meta->make_immutable();

And then you can use it in a controller (or anyplace where you have $c context).

    package Example::Controller::Root;

    use Moose;
    use MooseX::MethodAttributes;

    extends 'Catalyst::Controller';

    sub root :Chained(/) PathPart('') CaptureArgs(0) {} 

      sub not_found :Chained(root) PathPart('') Args {
        my ($self, $c, @args) = @_;
        $c->detach_error(404);
      }

    sub end :Does(RenderErrors) { }

    __PACKAGE__->config(namespace=>'');
    __PACKAGE__->meta->make_immutable;

DESCRIPTION

A set of Catalyst plugins, views and action roles to streamline handling of HTTP error responses. Creates a standard way to return 4xx and 5xx HTTP errors using properly content negotiation. Out of the box it support returning errors in HTML, JSON and Text, with errors in a number of common languages. Patches to support more languages and media types welcomed.

I wrote this to encapsulate a common pattern I noted emerging in many of my applications. Hopefully this will reduce boilerplate setup and speed your initial work. Also its never bad to have rational ways to do common things.

There is a very basic example application in /example for your review. This distribution doesn't have a ton of test cases and I reserve the right to make breaking changes should a better paradigm for this use case emerge. You should review the docs for each class in this distribution for more info.
