Getting started

EventStore is available in Hex and can be installed as follows:

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

     def deps do
       [{:eventstore, "~> 0.13"}]
     end

2. Add an eventstore config entry containing the PostgreSQL database connection details to each environment’s mix config file (e.g. config/dev.exs):

     config :eventstore, EventStore.Storage,
       serializer: EventStore.TermSerializer,
       username: "postgres",
       password: "postgres",
       database: "eventstore_dev",
       hostname: "localhost",
       pool_size: 10,
       pool_overflow: 5

   The database connection pool configuration options are:

• :pool_size - The number of connections (default: 10).
• :pool_overflow - The maximum number of overflow connections to start if all connections are checked out (default: 0).

3. Create the EventStore database and tables using the mix task:

     $ mix do event_store.create, event_store.init

Initialize an existing database

You can use an existing PostgreSQL database with EventStore by running the mix task:

$ mix event_store.init

Reset an existing database

To drop an existing EventStore database and recreate it you can run the mix task:

$ mix event_store.reset

Warning this will delete all EventStore data.
