Adding soft delete to a Phoenix Commanded (CQRS) API
So, I lied told a half-truth about aggregates. They are not hydrated in-memory for every command / event. In reality, aggregates are implemented with GenServer each caching their state and being managed under the commanded application's supervision tree (ultimately by a DynamicSupervisor called Commanded.Aggregates.Supervisor, to be specific).

Phoenix LiveView, but event-sourced
The context: I'm building a cryptocurrency exchange application. I don't have the business chops to run an actual exchange, so this is just for fun. The application is built in Elixir, using the Commanded framework for CQRS/ES goodness, and Phoenix LiveView because it's the hot new thing that I wanted to learn.
