Using CQRS in a simple Phoenix API with Commanded
Since I already had a Postgres database running, I decided to use EventStore rather than installing and babysitting EventStoreDB. To initialize the database and tables, I ran mix event_store.init and mix event_store.create.

Phoenix LiveView, but event-sourced
My goal is to use LiveView to update a price chart as trades are executed by the system. A LiveView process is a lot like a GenServer, with a bespoke process for each client, executing handle_* functions as the client does things. The first step to real-time chart updates is to trigger one of these handler functions in my LiveView controller when a trade is executed. I'm using Commanded's own EventStore library to dispatch and store my events, so their documentation is the place to start.

TIL: Non standard postgres types in livebook
But I found a problem when the data type is not supported by postgrex. In this case, you can either have to write a custom postgrex extension like the example here. In postgrex GitHub repo, there are many examples for common data types, but XML is missing there.

Realtime: Multiplayer Edition
It sounds like Supabase is pulling out the WAL listening bits into its own library?
