hello
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!
