Layered

Layered architecture is an ordered list. Earlier layers may depend on later layers. Later layers may not depend back outward.

architecture :layered, layers: {
  interface: "app/controllers/**/*.rb",
  application: "app/services/**/*.rb",
  domain: "app/models/**/*.rb"
}

This compiles to:

• components named interface, application, and domain
• allowlist dependency rules in layer order
• a cycle check across the layers

The default Rails-flavored layers are:

interface: "app/controllers/**/*.rb"
application: %w[app/services/**/*.rb app/jobs/**/*.rb app/mailers/**/*.rb]
domain: "app/models/**/*.rb"

You can also use:

preset :rails_layered
