Welcome to my talk, here are some of the modules
I will be talking about

Bread::Board is a Dependency Injection framework, available on CPAN

Plack is Web Infastructure-ware written by miyagawa

Plack::Middleware is the killer app of Plack

Path::Router is a module available on CPAN

... and of course Moose

But ﬁrst let me toast Open Source, for all the
collaboration and sharing of ideas that make it so much fun to participate in.

There is vast knowledge and great ideas to be found
out there, both in the ivory towers of CompSci departments and in other Open Source communities, it is time to rediscover some ...

This is a great book with a lot of Lambda
Calculus in it and the Y-Combinator is awesome, this kind of elegance and simplicity is not useful, but should be inspiring

Smalltalk is a great system from which too steal from,
Steve Jobs did it in the 80s, Ruby did it in the 90s and Moose did it in the 00s

Haskell is mind-bendingly insane and strikingly beautiful at the same
time

LISP is a wonderful language used by many really smart
people, we can learn from them too

Moose borrows shamelessly from all these technologies and more and
brings them to Perl

Miyagawa has been mining the knowledge of other Open Source
communities to bring us Plack and the next generation of Perl web tools

Now I would like to show you my latest experiment,
bringing together the modules I mentioned earlier.

The goal is simplicity and avoiding needless framework boilerplate or
useless subclassing

Here is an example of a simple counting program, over-engineered
to illustrate how the pieces of an OX::Application ﬁt together

This is the core of the Bread::Board conﬁg, notice the
circular dependency between View/Nib and Controller/Root, Bread::Board takes care of this.

This is the routing spec, it deﬁnes the available URLs
for the application and will automatically wire them to the controller dependencies

Here is the model, very simple plain old Moose class

Here is the controller, also a simple plain old Moose
class

This is an experiment in making TT work in a
way that is conceptually similar to Cocoa (the Mac OS X framework)

This is our .psgi ﬁle, it is so simple and
clean :)

This is our .psgi ﬁle evolved to take advantage of
some Plack::Middleware

Web apps should be easily testable too, here we fetch
Bread::Board services to test.

Here we use the Test::Path::Router to check the URLs our
web application will respond too

Here we use Plack::Test to test our web application

Holy crap, look at all the plugs in that outlet!
