RabbitMQ wrapper for Replay project.

Installation of RabbitMQ

Simply download and install RabbitMQ 3.6.4.

In order to manage the maximum amount of connections upon launch, open up and edit the following configuration file using nano:

sudo nano /etc/default/rabbitmq-server

Uncomment the limit line ulimit -n 1024 (i.e. remove the '#' in the last line), and don't forget to save before exit by pressing CTRL+X followed with Y.

Management plugin

First enable the management plugin by:

sudo rabbitmq-plugins enable rabbitmq_management

Then visit the following url to view the RabbitMQ management plugin, where you can view connections, channels, queues, and administer the RabbitMQ:

http://server-name:15672/

Default Username & Password are: guest.

If it doesn't work for some reason, maybe RabbitMQ is down. Try running this command:

sudo rabbitmqctl start_app

Environment variables

| Name | Description | Default | |----------------------------------|-------------------------------------|-----------------| | RABBITMQ_MAX_RESEND_ATTEMPS | Max attempts to resend messages | 3 | | RABBITMQ_FAILED_JOBS_QUEUE_NAME | Name of the queue for failed jobs | FailedJobsQueue |

Usage

First call to the connect method (which returns a Promise) to connect to rabbit.

Then, you can call the rest of the exported methods, such as consume, produce, etc.

Jobs that failed more than the allowed amount (RABBITMQ_MAX_RESEND_ATTEMPS) are sent to failed jobs queue.

Tests

We use mocha as our tests framework, therefore install mocha globally:

sudo npm install mocha -g

Now simply run the tests with npm:

npm test
