Getting started

The package can be installed from hex as follows.

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

   def deps do
     [{:commanded_eventstore_adapter, "~> 0.5"}]
   end
   

2. Include :eventstore in the list of extra applications to start in mix.exs:

   def application do
     [
       extra_applications: [
         :logger,
         :eventstore,
       ],
     ]
   end
   

3. Configure Commanded to use the Commanded.EventStore.Adapters.EventStore adapter:

   config :commanded,
     event_store_adapter: Commanded.EventStore.Adapters.EventStore
   

4. Configure the eventstore in each environment's mix config file (e.g. config/dev.exs), specifying usage of the included JSON serializer:

   config :eventstore, EventStore.Storage,
     serializer: Commanded.Serialization.JsonSerializer,
     username: "postgres",
     password: "postgres",
     database: "eventstore_dev",
     hostname: "localhost",
     pool_size: 10
   

5. Create the eventstore database and tables using the mix task:

   $ mix do event_store.create, event_store.init
