IronMQ

Page last updated:

IronMQ is a reliable message queue service that lets you connect systems and build distributed apps that scale effortlessly and eliminate any single points of failure.

Managing Services

To create and bind a service instance, see Managing services from the command line.

Using Service Instances with your Application

See Delivering Service Credentials to an Application and VCAP_SERVICES Environment Variable.

Format of credentials in VCAP_SERVICES environment variable:

{
   ironmq: [
      {
         name: "ironmq",
         label: "ironmq",
         tags: [ ],
         plan: "small",
         credentials: {
            project_id: "52fc1f640738fa0009000007",
            token: "wskYhifzt1Nl2XjwhGAZ0jfXLDo"
         }
      }
   ]
}

Language Support

IronMQ has clients for a lot of languages, and you can always use the REST API (or write your own!).

Ruby

We’re going to need to install the Ruby gem, for development purposes:

$ gem install iron_mq

If you’re building for a Rails application or anything that uses Bundler, add the following to your Gemfile:

gem 'iron_mq'

Now you have a simple helper that allows you to interact with your queues:

# Create an IronMQ::Client object
@ironmq = IronMQ::Client.new()

# Get a queue (if it doesn't exist, it will be created when you first post a message)
@queue = @ironmq.queue("my_queue")

# Post a message
@queue.post("hello world!")

# Get a message
msg = @queue.get()
p msg

# Delete a message (you must delete a message when you're done with it or it will go back on the queue after a timeout)
msg.delete # or @queue.delete(msg.id)

Java

We’re going to need to install the jar file for the official IronMQ Java library. If you’re using Maven, you can also add the http://iron-io.github.com/maven/repository repository as a dependency.

Once you have the jar file added as a dependency, you have a simple wrapper that allows you to interact with your queues:


// Get your Iron.io credentials from the environment
Map env = System.getenv();

// Create a Client object
Client client = new Client(env.get("IRON_MQ_PROJECT_ID"), env.get("IRON_MQ_TOKEN"), Cloud.IronAWSUSEast);

// Get a queue (if it doesn't exist, it will be created when you first post a message)
Queue queue = client.queue("my_queue");

// Post a message
queue.Push("hello world!");

// Get a message
Message msg = queue.get();
System.out.println(msg.getBody());

// Delete a message (you must delete a message when you're done with it or it will go back on the queue after a timeout)
queue.deleteMessage(msg);

Python

We’re going to have to install the Python client library for IronMQ. You can do this using pip install iron_mq or easy_install iron_mq.

Once the package is installed, you have a simple wrapper that allows you to interact with your queues:

# Create an IronMQ client object
mq = IronMQ()

# Get a queue (if it doesn't exist, it will be created when you first post a message)
queue = mq.queue("my_queue")

# Post a message
queue.post("hello world!")

# Get a message
msg = queue.get()
print msg

# Delete a message (you must delete a message when you're done with it or it will go back on the queue after a timeout)
queue.delete(msg["messages"][0]["id"])

Clojure

We’re going to need to add the IronMQ Clojure client to your project.clj:

[iron_mq_clojure "1.0.3"]

Use these to create a client that allows you to interact with your queues:

(require '[iron-mq-clojure.client :as mq])

(def client (mq/create-client (System/getenv "IRON_MQ_TOKEN") (System/getenv "IRON_MQ_PROJECT_ID")))

; Post a message
(mq/post-message client "my_queue" "Hello world!")

; Get a message
(let [msg (mq/get-message client "my_queue")]
(println (get msg "body"))

; Delete a message (you must delete a message when you're done with it or it will go back on the queue after a timeout)
(mq/delete-message client "my_queue" msg))

Node.js

We’re going to need to the IronMQ Node.js client to interact with our queues. You can get it using npm install iron_mq or by downloading the source from Github (though you’ll need [iron_core_node]9, too).

Once that’s done, you can require it to get a simple wrapper for the API:

var iron_mq = require("iron_mq");

var client = new iron_mq.Client({"queue_name": "my_queue"});

// Post a message
client.post("test message", function(error, body) {
console.log(body);
console.log(error);
});

// Get a message
client.get({}, function(error, body) {
console.log(error);
console.log(body);
if(error == null) {
// Delete a message
client.del(body["id"], function(error, body) {
console.log(error);
console.log(body);
});
}
});
