Event Driven

Event-driven architecture is modeled as events, publishers, and subscribers.

architecture :event_driven

This checks:

  • event definitions do not depend on publishers or subscribers
  • publishers only depend on declared events
  • subscribers only depend on declared events
  • the declared components do not form cycles

The default Rails-flavored directories are:

events: "app/events/**/*.rb"
publishers: "app/publishers/**/*.rb"
subscribers: "app/subscribers/**/*.rb"

Pass any of those keys to override the defaults.

This is intentionally narrow. It checks source-level coupling, not event delivery semantics.
