Combine Multiple Catalyst Applications

temporal has asked for the wisdom of the Perl Monks concerning the following question:

Monks,

I have developed multiple Catalyst applications and right now they are all separate standalone apps. I'd really like to bring all of these apps under a single point of access.

Currently, I have my apps running individually on different ports deployed using Catalyst's built-in HTTP server. This is not really that pretty or efficient and I don't like having so many open ports. Ideally, I'd like to run them all under port 80 and manage them all through a single instance of Catalyst.

Now, I know that I could just merge all of their files/directories under one mega-project. This would be painfully unorganized, as the different pieces of all the different apps would be completely mixed up. Not to mention I would have to fix the logic for overlapping controller methods. This would quickly become difficult to manage.

Is it possible to keep my apps distinct but run them under a single Catalyst built-in HTTP server? Or perhaps it is time to graduate to a dedicated server application (nginx) and use different virtual hosts... I would miss the portability of the built-in server.

Helpful reading– Plack::Builder Plack::Middleware Plack::App::URLMap Plack::Middleware::Conditional plackup Plack::Middleware::Session and PSGI—might help unify apps by, e.g., sharing sessions via `psgix.session`. `# If you're not reasonably up to date- sudo cpanm Plack Catalyst Catalyst::Devel` [download] Full steps for testing two Cat apps in one server `# *nix centric. mkdir cattest cd cattest catalyst.pl OneFish catalyst.pl TwoFish vi^W emacs a-one-an-a-two-a.psgi # But I keed!` [download] a-one-an-a-two-a.psgi `#!/usr/bin/env perl use strict; use Plack::Builder; use FindBin; use lib "$FindBin::Bin/OneFish/lib", "$FindBin::Bin/TwoFish/lib"; use OneFish; use TwoFish; my $app = builder { mount "/two" => TwoFish->psgi_app(@_); mount "/" => OneFish->psgi_app(@_); # Root needs to be last or it'll eat others. };` [download] Run, dog, run `env CATALYST_DEBUG=0 plackup a-one-an-a-two-a.psgi HTTP::Server::PSGI: Accepting connections at http://0:5000/` [download] Visit http://localhost:5000/ (or whatever name/ip your box prefers) and http://localhost:5000/two/ and don't forget to tip your servers. Caveat: this might lead to entangling or making cross-dependent coding choices which would be bad. Make an effort to keep things compartimental. Abstract and separate commonality like sessions/auth. If each app can't run alone after you're done, you might as well have rolled them all into one to start.	[reply] [d/l] [select]

Thanks! Exactly what I was looking for (and entertaining to boot). I was peripherally aware of Plack. Now I have become FULLY aware. O_O Very handy.	[reply]

Get to know Plack . . . very, very, very well.	[reply]

Is there a way to mount by domain name instead of path? I have multiple apps that I need to differentiate by which domain name is requesting them.	[reply]

Pretty sure there is; with a middleware mapper. Why don’t you post a new question/thread though so it’s not stuck down here?	[reply]
