Jobi

A simple framework for Ruby, provides a full interaction between your app/micro-service and message brokers like: (Rabbitmq, Kafka, ..etc).
Currently it only support Rabbitmq.

Requirements

• Rabbitmq server installed and ready.

Installation

Add this line to your application's Gemfile:

gem 'jobi'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install jobi

Setup

• Add the below code to your app:

Jobi.configure do |config|
    config.rabbitmq
    config.act_as_publisher = true
    config.act_as_consumer = true
    config.jobs = ['{Your Job classes goes here}']
    config.log_file = 'log/jobi.log'
    config.log_level = :debug
end

• To change rabbitmq client configuration you can do the following:

Jobi.configure do |config|
    # same as the above example
    # and you can add the below one:
    config.rabbitmq(
        {
            host: ENV['RABBITMQ_HOST'],
            port: ENV['RABBITMQ_PORT'],
            user: ENV['RABBITMQ_USER'],
            pass: ENV['RABBITMQ_PWD'],
            vhost: '/',
            auth_mechanism: 'PLAIN',
            heartbeat: 'server',
            automatically_recover: true,
            network_recovery_interval: 5.0,
            ssl: false,
            threaded: true,
            continuation_timeout: 4000,
            frame_max: 131_072
        }
    )
end

• For rails you can do the following:

# config/initializers/jobi.rb
Jobi.configure do |config|
    # You can add the above examples here safely.
end

Usage

• Create an asynchronous job:

class ExampleJob < Jobi::Job
    # Queue name that will be used for publishing and consuming messages.
    # Force acknowledge of the message or not.
    # Number of consumers that will consume from this queue.
    # Queue durability to survive broker restart, by default it is true.
    # Message persistence to survive broker restart.
    options queue_name: :example,
            ack: true,
            consumers: 5,
            durable: true,
            persist: true

    # Will be called after run.
    after_run :print_sum

    # Entry point of the job
    def initialize(arg1:, arg2:)
        @arg1 = arg1
        @arg2 = arg2
    end

    def run
        # Your custom logic goes here
        @sum = @arg1 + @arg2
    end

    private

    def print_sum
        # Your custom logic that will run after
        # the execution of your job.
        puts @sum
    end
end

Then you can call it like this:

ExampleJob.run(arg1: 1, arg2: 2)
