Getting started

The package can be installed from hex as follows.

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

    def deps do
      [{:commanded_extreme_adapter, "~> 1.0"}]
    end

2. Define and configure your Commanded application:

    defmodule MyApp.Application do
      use Commanded.Application, otp_app: :my_app
    end

3. Configure the Commanded application to use the Commanded.EventStore.Adapters.Extreme adapter and set the connection settings for the Event Store you are using:

    # config/config.exs
    config :my_app, MyApp.Application,
      event_store: [
        adapter: Commanded.EventStore.Adapters.Extreme,
        serializer: Commanded.Serialization.JsonSerializer,
        stream_prefix: "myapp",
        extreme: [
          db_type: :node,
          host: "localhost",
          port: 1113,
          username: "admin",
          password: "changeit",
          reconnect_delay: 2_000,
          max_attempts: :infinity
        ]
      ]

   Refer to the Extreme library documentation for details on the available connection settings.

   Note: Stream prefix must not contain a dash character ("-").

Running the Event Store

You must run the Event Store with all projections enabled and standard projections started.

Use the --run-projections=all --start-standard-projections=true flags when running the Event Store executable.
