SneakersPacker

SneakersPacker is a gem for using sneakers to realize 3 message communication patterns job message, broadcast and RPC(remote procedure call).

Intall the `sneakers' gem first. see sneakers

Then add this line to your application's Gemfile:

gem 'sneakers_packer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sneakers_packer

SneakersPacker uses most of sneakers configuration for simpleness. There are app_name and rpc_timeout should be set for SneakersPacker.

Append below to config/initializers/sneakers.rb.

SneakersPacker.configure do |conf|
  conf.rpc_timeout = 3             # rpc client timeout. default is 5 seconds.
  conf.app_name = "sneakers_test"  # rpc client or server app's name. default is 'unknown'
end

• Job Message

Client

SneakersPacker.publish("demo", "hello world")

Server

  class DemoWorker
    include SneakersPacker::CommonWorker
    from_queue :demo

    def call(data)
      puts "data is #{data}"
      # do something...
    end
  end

• Broadcast

Client

It is same with Job Message

SneakersPacker.publish("demo.suprise", "hello world")

Server

It is almost same with Job Message except that one routing_key with multiple queues.

  class OneWorker
    include SneakersPacker::CommonWorker

    from_queue :one_name, routing_key: "demo.suprise"

    def call(data)
      puts "one: #{data}"
      # do something...
    end
  end

  class OtherWorker
    include SneakersPacker::CommonWorker

    from_queue :other_name, routing_key: "demo.suprise"

    def call(data)
      puts "other: #{data}"
    end
  end

• RPC

Client

remote call with default timeouit. default is 5 seconds. SneakersPacker.remote_call("rpc_server", 10)

remote call with custom timeouit. SneakersPacker.remote_call("rpc_server", 12, timeout: 2)

Server

  class RpcServerWorker
    include SneakersPacker::RpcWorker

    from_queue :rpc_server

    # return value of call will be result of remote procedure call
    def call(data)
      data.to_i ** 3
    end
  end
