Catalyst::Manual::Components(3p)

NAME
Catalyst::Manual::Components - Reuseable components for Catalyst applications

DESCRIPTION
This section lists the some of the components (and plugins) that are available to extend the runtime functionality of Catalyst. Most components are not distributed with Catalyst but should be available from CPAN. They typically require additional modules from CPAN.

This list may well be outdated by the time you read this, and some plugins may be deprecated, or, conversely, may now part of core Catalyst. Be sure to check the Catalyst:: and CatalystX:: namespaces for additional components, and consult the mailing list ( <http://dev.catalyst.perl.org/wiki/Support> ) for advice on the current status or preferred use of your chosen plugin/framework.

PLUGINS

  Catalyst::Plugin::Account::AutoDiscovery
Provides Account Auto-Discovery for Catalyst.

  Catalyst::Plugin::Acme::Scramble
Implements a potent meme about how easily we can read scrambled text if the first and last letters remain constant. Operates on text/plain and text/html served by your Catalyst application.

  Catalyst::Plugin::Alarm

  Catalyst::Plugin::AtomPP
Allows you to dispatch AtomPP methods.

  Catalyst::Plugin::AtomServer
A plugin that implements the necessary bits to make it easy to build an Atom API server for any Catalyst-based application.

  Catalyst::Plugin::Authentication
An infrastructure plugin for the Catalyst authentication framework. Now the recommended way to do any form of Authentication.

Note that newer versions of the authentication plugin allow multiple "realms", so that you can authenticate users in different ways in different parts of your application.

This, however, has involved deprecated all classes in the "Catalyst::Plugin::Authentication::Credential::XXX" and "Catalyst::Plugin::Authentication::Store::XXX" namespaces.

These plugins are still usable, but they have mostly been replaced with new modules in the new namespace which will work together.

Available Credential modules:

Catalyst::Authentication::Credential::AuthTkt

Allows you to use the Apache::AuthTkt module with Catalyst.

Catalyst::Authentication::Credential::FBConnect

Allows you to authenticate Facebook users using the FBConnect API.

Catalyst::Authentication::Credential::Flickr

Provides authentication via Flickr, using its API.

Catalyst::Authentication::Credential::HTTP

Allows you to authenticate users using HTTP Basic or Digest authentication.

Catalyst::Authentication::Credential::HTTP::Proxy

Allows you to authenticate users against a remote web server offering HTTP authentication.

Catalyst::Authentication::Credential::Kerberos

Allows you to authenticate your users against a Kerberos server.

Catalyst::Authentication::Credential::OAuth

Allows you to authenticate users using their login on other websites supporting the OAuth protocol.

Catalyst::Authentication::Credential::OpenID

Allows you to authenticate users using their login on other websites supporting the OpenID protocol.

Catalyst::Authentication::Credential::Password

Takes a username (or userid) and a password, and tries various methods of comparing a password based on what the chosen store's user objects support. Part of the Authentication Framework Catalyst::Plugin::Authentication.

Catalyst::Authentication::Credential::RPX

Allows you to authenticate users using the RPX protocol.

Catalyst::Authentication::Credential::Remote

Allows you to authenticate users in Catalyst that have already been authenticated by your web server. This is useful for authenticating users with SSL Client certificates, and using NTLM or any other authentication protocol natively supported by your web server.

Catalyst::Authentication::Credential::Testing

Allows you to set the same password for all users, which is useful when you want to test logging in as multiple users or multiple types of user, without having to mock things, or set all users' passwords in your test suite.

Catalyst::Authentication::Credential::Authen::Simple

Allows any of the Authen::Simple family of modules to be used to authenticate users in Catalyst.

Available Store modules:

Catalyst::Authentication::Store::DBIx::Class

Does authentication and authorization against a DBIx::Class model.

Catalyst::Authentication::Store::Htpasswd

Uses Authen::Htpasswd to let your application use ".htpasswd" files for its authentication storage.

Catalyst::Authentication::Store::AuthTkt

This module implements the Catalyst::Authentication API for Apache::AuthTkt.

Catalyst::Authentication::Store::DBI

Allows you to use a plain DBI database connection to identify users.

Catalyst::Authentication::Store::Htpasswd

Catalyst::Authentication::Store::Minimal

Lets you create a very quick and dirty user database in your application's config hash. Great for getting up and running quickly.

The Null store is a transparent store where any supplied user data is accepted. This is mainly useful for remotely authenticating credentials (e.g. OpenID) which may not be tied to any local storage.

Catalyst::Authentication::Store::RDBO

Catalyst::Authentication::Store::Tangram

Allows access to authentication information stored in a database via a Tangram class.

  Catalyst::Plugin::Unicode
Disrecommended plugin which tries to autodetect the uft8ness of the output and do the correct thing. This may work in some cases, but if it helps, you've already painted yourself into a corner - try to avoid!

  Catalyst::Plugin::Upload::Basename

  Catalyst::Plugin::Upload::MD5

  Catalyst::Plugin::UploadProgress

  Catalyst::Plugin::XMLRPC
Allows your Controller class to dispatch XMLRPC methods from its own class.

MODELS

  Catalyst::Model::CDBI
The "Class::DBI" (CDBI) model class. It is built on top of "Class::DBI::Loader", which automates the definition of "Class::DBI" sub-classes by scanning the underlying table schemas, setting up columns and primary keys.

  Catalyst::Model::CDBI::Plain
A neutral interface to the "Class::DBI" module which does not attempt to automate table setup. It allows the user to manually set up "Class::DBI" classes, either by doing so within the Catalyst model classes themselves, or by inheriting from existing "Class::DBI" classes.
