YAPC::NA 2015 Wrap-up and More New (PSGI!) Modules

I was lucky enough to be able to attend YAPC::NA 2015 in Salt Lake City, this year. First and foremost I have to applaud the organizers, the event was so well coordinated it looks positively effortless, which I’m sure masked the huge amount of effort that it takes to appear so.

After not being able to attend the last two YAPC::NAs, it was such a joy to be back. As my new friend VM Brasseur has been saying in #yapc lately, “these are my people.” The community feeling at all Perl meetings, and especially at YAPC::NA, is overwhelming and I loved meeting and reconnecting with so many fellow Perlers.

New CPAN Modules

I have found myself in a bit of a CPAN exuberance these last few months. While I have released several new modules, I haven’t found time to announce them individually. Here then is a joint announcement of what I’ve been doing on CPAN lately.

Come to MojoConf and tell us something cool!

Maybe you are already registered for this year’s MojoConf in New York City (June 4th-6th) or maybe you are still thinking about it. Either way, a great way to introduce yourself to the Mojolicious community is to give a talk! But what should you talk about? The cool stuff you do with Mojolicious!

Last years talks were on a wide range of topics. When I write a talk, I usually write really technical talks; I’m always trying to pack too much code into each slide. But when I’m in the audience, the ones that really knock my socks off are the ones I don’t expect.

Last year, Rich Elberger (this year’s host, incidentally) gave a talk that took me completely by surprise, he’s gaining traction using Mojolicious in an Enterprise system! How cool is that?!

So this year I’m really looking forward to seeing all the interesting ways that people are using Mojolicious! Maybe you wrote a cool app, or an interface to an API that’s popular or one that going to be. Maybe you are using Mojolicious to do some system task or solve a real-world problem.

Then again, tutorials are useful too. There are going to be lots of newcomers to Mojolicious. Maybe you want to tell us about your favorite Mojolicious feature and how to use it. Maybe you wrote a module on CPAN that you would like to show off. Maybe a construction technique that you find useful.

I’m really looking forward to this year’s MojoConf and I’m hoping to be delighted by new things, big or small! I hope to see you (and maybe even hear you) there!

You have nothing to lose but your chains!

Perhaps a misleading title. Seeing as this is not a political blog but a Perl one, I’m going to talk about method chaining, not worker’s unions.

Method chaining is the practice of consecutively calling methods on the return of a previous method. This comes in primarily two flavors. The first isn’t as common in Perl, though it is used extensively in Mojolicious, is when a method has nothing useful to return, it can return itself. This allows for say chaining setter methods $self->set_foo("FOO")->set_bar("baz"), or chaining related test methods

my $t = Test::Mojo->new;
$t->get_ok('/page/1/')
   ->status_is(200)
   ->text_like('#id' => qr/foo/);

While this is useful, it’s not my topic today. I’m going to talk about the more simple form, calling a method that returns an object, then calling a method on it, and so on.

Mojolicious: Do It For The Candy!

Most of my recent blog posts about Mojolicious have revolved around its non-blocking capabilities. I like to write about those because I think that it is those capabilities that can bring new eyes to Perl from other languages, much like Node.js brought eyes to server-side javascript (for the same reason). That said, lately I have had excuses to show off Mojolicious and when I have done so, it has been some of the other cool features that have garnered the “Ooooh”s and “Aaaah”s from onlookers.

In this article I will show you some of those extras, like accessing your generated pages and even app itself direcly from the command line. I will also show how testing can be easy, powerful, expressive and yet still readably beautiful.
