CQRS

CQRS is modeled as commands, queries, and optional read models.

architecture :cqrs

This checks:

  • commands do not depend on queries
  • queries do not depend on commands
  • queries do not call obvious mutating methods such as save!, update!, or destroy!
  • the declared components do not form cycles

The default Rails-flavored directories are:

commands: "app/commands/**/*.rb"
queries: "app/queries/**/*.rb"
read_models: "app/read_models/**/*.rb"

Pass any of those keys to override the defaults.

This is a structural check. It does not prove that every read and write path obeys CQRS at runtime.
