Some modules start to appear on CPAN and github to add functionalities, or to extend existing ones. + +Templates +--------- + +By default, Dancer comes with support for two templating systems: Template Toolkit and Dancer::Template::Simple, a small templating engine written by sukria. But support for other templating systems are available: + +Dancer +Template::Tenjin by ido + +Dancer +Template::Sandbox by Sam Graham + +Dancer +Template::Tiny by Sawyer + +Dancer +Template::MicroTemplate by me + +Dancer +Template::Mason by Yanick Champoux + +Dancer +Template::Haml by David Moreno + +Logger +------ + +Out of the box, Dancer only has a simple logging system to write to file, but more logging sytems are available: + + <ul> + + <li> + +Dancer::Logger::Syslog by sukria + + </li> + + <li> + +Dancer::Logger::LogHandler by me + + </li> + + <li> + +Dancer::Logger::PSGI by me + + </li> + + </ul> + +The last one is for writing directly your log message via Plack. You can use a middleware like P::M::LogDispatch or P::M::Log4perl to handle logs for your application. Even better, if you use P::M::ConsoleLogger, you can have logs from your Dancer application in your javascript console. + +Debug +----- + +To debug your application with Plack, you can use the awesome Plack::Middleware::Debug. I've writen Dancer::Debug (which requires my fork of P::M::Debug), a middleware that add panels, with specific informations for Dancer applications. + +To activate this middleware, update your app.psgi to make it look like this: + +``` perl + my $handler = sub { + my $env = shift; + my $request = Dancer::Request->new($env); + Dancer->dance($request); + }; + $handler = builder { + enable "Debug", panels => [ + qw/Dancer::Settings Dancer::Logger Environment Memory + ModuleVersions Response Session Parameters Dancer::Version / + ]; + $handler; + }; +``` + +Plugins +------- + +Dancer has support for plugins since a few version. There is not a lot of plugins at the moment, but this will soon improve. Plugins support is one of the top priorities for the 1.2 release. + +**\*** Dancer::Plugin::REST + +This one is really nice. This plugin, used with the serialization stuff, allow you to write easily REST application. + +``` perl + resource user => get => sub { # return user where id = params->{id} }, + create => sub { # create a new user with params->{user} }, + delete => sub { # delete user where id = params->{id} }, + update => sub { # update user with params->{user} }; +``` + +And you got the following routes: + +- GET *user*:id +- GET *user*:id.:format +- POST /user/create +- POST /user/create.:format +- DELETE *user*:id +- DELETE *user*:id.:format +- PUT *user*:id +- PUT *user*:id.:format + +\*\*\* Dancer::Plugin::Database + +This plugin, by bigpresh, add the database keyword to your app. + +``` perl + use Dancer; + use Dancer::Plugin::Database; + + # Calling the database keyword will get you a connected DBI handle: + get '/widget/view/:id' => sub { + my $sth = database->prepare('select * from widgets where id = ?', + {}, params->{id}); + $sth->execute; + template 'display_widget', {widget => $sth->fetchrow_hashref}; + }; +``` + +**\*** Dancer::Plugin::SiteMap + +With this plugin, by James Ronan, a sitemap of your application is created. + + <blockquote> + +Plugin module for the Dancer web framwork that automagically adds sitemap routes to the webapp. Currently adds /sitemap and /sitemap.xml where the former is a basic HTML list and the latter is an XML document of URLS. + + </blockquote> + +you can help! :) +---------------- + +There is still a lot of stuff to do. Don't hesitate to come on \#dancer@irc.perl.org to discuss ideas or new features that you would like. |
