Installation

The package can be installed by adding helios to your list of dependencies in mix.exs:

def deps do
  [
    {:helios, "~> 0.2"}
  ]
end

Configuration

It is important to knwo that there is minimum configuration that has to be explicitly configured in your application, without it application will not work or start.

Default Event Journal

use Mix.Config

config :your_app, :default_journal,
  YourApp.DefaultJournal

# you also need to configure that journal
config :your_app, YourApp.DefaultJournal,
  adapter: Helios.EventJournal.Adapter.Memory # ETS journal
  adapter_config: []

or, if you need to persist events over application restarts

use Mix.Config

config :your_app, :default_journal,
  YourApp.DefaultJournal

config :your_app, YourApp.DefaultJournal,
  adapter: Helios.EventJournal.Adapter.Eventstore
  adapter_config: [
    db_type: :node,
    host: "localhost",
    port: 1113,
    username: "admin",
    password: "changeit",
    connection_name: "your_app",
    max_attempts: 10
  ]

don't forget to add extreme dependency to your project {:extreme, "~> 0.13"}
