Installation

Add :broadway_rabbitmq to the list of dependencies in mix.exs:

def deps do
  [
    {:broadway_rabbitmq, "~> 0.1.0"}
  ]
end

Usage

Configure Broadway with one or more producers using BroadwayRabbitMQ.Producer:

  defmodule MyBroadway do
    use Broadway

    def start_link(_opts) do
      Broadway.start_link(__MODULE__,
        name: __MODULE__,
        producers: [
          default: [
            module: {BroadwayRabbitMQ.Producer,
              queue: "my_queue",
            },
            stages: 2
          ]
        ],
        processors: [
          default: [
            stages: 50
          ]
        ]
      )
    end

    def handle_message(_, message, _) do
      IO.inspect(message.data, label: "Got message")
      message
    end
  end

Metadata

Use the metadata option with a list of atoms of the attributes we want to retrieve from AMQP producer:

Broadway.start_link(MyBroadway,
  name: MyBroadway,
  producers: [
    default: [
      module: {BroadwayRabbitMQ.Producer,
        queue: "my_queue",
        metadata: [
          :routing_key,
          :redelivered,
          :headers
        ]
      }
    ]
  ]
)
