sidekiq-aws-sqs is a Sidekiq extension that simplifies the integration of AWS SQS queues with Sidekiq workers, by abstracting away the details of polling, processing and error handling of SQS messages. It aims to provide a reliable and flexible way to consume messages from SQS, while allowing the user to customize the polling behavior and SQS client options as needed.

At its core, sidekiq-aws-sqs uses the SafePoller gem to implement a background thread that polls messages from the specified SQS queue at a specified interval. The polling logic is encapsulated in a poll method that is meant to be called from a Sidekiq worker, passing a block of code that will process each message received. The poll method returns a handle to the SafePoller instance, which can be used to start, stop, pause or resume the polling process as needed. The polling process can also be configured to stop after a specified time or date, or to stop automatically when Sidekiq shuts down or terminates.

To use sidekiq-aws-sqs in a Sidekiq worker, you simply need to include the Sidekiq::AWS::SQS module and call the poll method with the desired options and block of code. You can also customize the SQS client and polling options by setting class-level variables, or by passing them as options to the poll method.

Install the gem and add to the application's Gemfile by executing:

$ bundle add sidekiq-aws-sqs

Or add the following line to the application's Gemfile:

gem 'sidekiq-aws-sqs', github: 'nejdetkadir/sidekiq-aws-sqs', branch: 'main'

If bundler is not being used to manage dependencies, install the gem by executing:

gem install sidekiq-aws-sqs

require 'sidekiq/aws/sqs'

class MyWorker
  include Sidekiq::Worker
  include Sidekiq::AWS::SQS::Worker

  sqs_options queue_url: 'https://sqs.foo.amazonaws.com/123/bar',
              wait_time_seconds: 20, # optional, default: 20
              destroy_on_received: true, # optional, default: false
              max_number_of_messages: 10, # optional, default: 10
              client: Aws::SQS::Client.new # optional if global config is set to Sidekiq::AWS::SQS.config.sqs_client

  def perform(message)
    parsed_message = JSON.parse(message, symbolize_names: true)

    puts "Received message: #{parsed_message[:body]}"
  end
end

You can configure the global options for all sqs workers by creating an initializer file in config/initializers/sidekiq_aws_sqs.rb and setting the options as shown below.

# config/initializers/sidekiq_aws_sqs.rb

require 'sidekiq/aws/sqs'
require 'aws-sdk-sqs'

Sidekiq::AWS::SQS.configure do |config|
  config.sqs_client = Aws::SQS::Client.new # global SQS client for all sqs workers

  # you must set the your sqs workers here for registering them to sidekiq aws sqs
  config.sqs_workers = [
    MyWorker
  ]

  # global polling options for all sqs workers
  config.wait_time_seconds = 20 # optional, default: 20
  config.destroy_on_received = true # optional, default: false
  config.max_number_of_messages = 10 # optional, default: 10
  config.logger = Sidekiq.logger # optional, default: Sidekiq.logger
end
