-title: presque, a Redis / Tatsumaki based message queue
----
-
-"presque":http://github.com/franckcuny/presque/tree/ is a small message queue service build on top of "redis":http://code.google.com/p/redis/ and "Tatsumaki":http://search.cpan.org/perldoc?Tatsumaki. It's heavily inspired by "RestMQ":http://github.com/gleicon/restmq and "resque":http://github.com/defunkt/resque.
-
- * Communications are done in JSON over HTTP
- * Queues and messages are organized as REST resources
- * A worker can be writen in any language that make a HTTP request and read JSON
- * Thanks to redis, the queues are persistent
-
-h3. Overview
-
-resque need a configuration file, writen in YAML that contains the host and port for the Redis server.
-
-{% highlight yaml %}
-redis:
-    host: 127.0.0.1
-    port: 6379
-{% endhighlight %}
-
-Let's start the server:
-
-{% highlight bash %}
-$ plackup app.psgi --port 5000
-{% endhighlight %}
-
-The applications provides some HTTP routes:
-
- * */*: a basic HTML page with some information about the queues
- * */q/*: REST API to get and post job to a queue
- * */j/*: REST API to get some information about a queue
- * */control/*: REST API to control a queue (start or stop consumers)
- * */stats/*: REST API to fetch some stats (displayed on the index page)
-
-Queues are created on the fly, when a job for an unknown queue is inserted. When a new job is created, the JSON send in the POST will be stored "as is". There is no restriction on the schema or the content of the JSON.
-
-Creating a new job simply consist to :
-
-{% highlight bash %}
-curl -X POST "http://localhost:5000/q/foo" -d '{"foo":"bar", "foo2":"bar" }'
-{% endhighlight %}
-
-and fetching the job:
-
-{% highlight bash %}
-curl "http://localhost:5000/q/foo"
-{% endhighlight %}
-
-When a job is fetched, it's removed from the queue.
-
-h3. A basic worker
-
-I've also uploaded "presque::worker":http://github.com/franckcuny/presque-worker/tree/ to github. It's based on "AnyEvent::HTTP":http://search.cpan.org/perldoc?AnyEvent::HTTP and "Moose":http://search.cpan.org/perldoc?Moose. Let's write a basic worker using this class:
-
-{% highlight perl %}
-use strict;
-use warnings;
-use 5.012;    # w00t
-
-package simple::worker;
-use Moose;
-extends 'presque::worker';
-
-sub work {
-    my ($self, $job) = @_;
-    say "job's done";
-    ...;      # yadda yadda!
-    return;
-}
-
-package main;
-use AnyEvent;
-
-my $worker =
-    simple::worker->new(base_uri => 'http://localhost:5000', queue => 'foo');
-
-AnyEvent->condvar->recv;
-{% endhighlight %}
-
-A worker have to extends the presque::worker class, and implement the method *work*. When the object is created, the class check if this method is avalaible. You can also provide a **fail** method, which will be called when an error occur.
-
-h3. The future
-
-I plan to add support for "websocket":http://en.wikipedia.org/wiki/WebSocket, and probably "XMPP":http://en.wikipedia.org/wiki/Xmpp. More functionalities to the worker too: logging, forking, handling many queues, ... I would like to add priorities to queue also, and maybe scheluding job for a given date (not sure if it's feasable with Redis).
