Redix.PubSub.Fastlane

Fastlane pattern based on Redix.PubSub interface for Elixir

See the docs for more information.

TL;DR Example Phoenix app

About

Works as a simple wrapper over Redix.PubSub.

Main goal is providing a fastlane path for published events.

Imagine: You have a Main task, that depends on few subtasks, each with its own UUID & await for published event, but also wants the Main task ID within every event.

Ie:

Redix.PubSub.Fastlane.subscribe(MyApp.PubSub.Redis, "channel1", {pid, My.Fastlane, ["some_id"]})

Installation

redix_pubsub_fastlane can be installed as:

1. Add redix_pubsub_fastlane to your list of dependencies in mix.exs:

def deps do
  [{:redix_pubsub_fastlane, "~> 0.3.1"}]
end

2. Ensure redix_pubsub_fastlane is started before your application:

def application do
  [applications: [:redix_pubsub_fastlane]]
end

3. Also you can simply add it to your Mix.config:

config :redix_pubsub_fastlane, MyApp.PubSub.Redis,
  fastlane: My.Fastlane,
  host: "192.168.1.100"

Usage

Simply add it to your Supervisor stack:

supervisor(Redix.PubSub.Fastlane, [MyApp.PubSub.Redis, [host: "localhost",
                                                        port: 6397,
                                                        pool_size: 5]])

Or run it by hands:

{:ok, pubsub_server} = Redix.PubSub.Fastlane.start_link(MyApp.PubSub.Redis)
