Command auditing middleware for Commanded CQRS/ES applications.

Records every dispatched command to the configured database storage. Includes whether the command was successfully handled, or any error.

Installation

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

   def deps do
     [
       {:commanded_audit_middleware, "~> 0.1"},
     ]
   end

2. Add the following config section to config/config.exs:

   config :commanded_audit_middleware,
     ecto_repos: [Commanded.Middleware.Auditing.Repo],
     serializer: Commanded.Serialization.JsonSerializer

3. Add the following config section to each environment's config (e.g. config/dev.exs):

   config :commanded_audit_middleware, Commanded.Middleware.Auditing.Repo,
     adapter: Ecto.Adapters.Postgres,
     database: "commanded_audit_middleware_dev",
     username: "postgres",
     password: "postgres",
     hostname: "localhost",
     port: "5432"

4. Fetch and compile mix dependencies:

   $ mix do deps.get, deps.compile

5. Create and migrate the command audit database:

   $ mix ecto.create -r Commanded.Middleware.Auditing.Repo
   $ mix ecto.migrate -r Commanded.Middleware.Auditing.Repo

6. Add the middleware to your application's Commanded router.

   defmodule Router do
     use Commanded.Commands.Router
   
     middleware Commanded.Middleware.Auditing
   end
