Getting Started.md

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, "~> 1.1"}]
   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.
