Building a CQRS/ES web application in Elixir using Phoenix
- slashdotdash 10y agoA case study describing how I built a web app following a Command Query Responsibility Segregation and event sourcing (CQRS/ES) pattern. In Elixir using the Phoenix Framework. It uses two open-source Elixir libraries I've authored to provide the building blocks for such applications: * EventStore: A CQRS event store that uses PostgreSQL (v9.5 or later) as the underlying storage engine. [1] * Commanded: Provides support for command registration and dispatch; hosting and delegation to aggregate roots; event handling; and long running process managers. [2] It's an unorthodox approach to building Phoenix web apps. The article details why you might consider applying it.
