Cycles

Cycles make architecture harder to change because two components become one unit in practice.

no_cycles

Rule id: dependencies.no_cycles

Limit the check to specific components:

no_cycles among: %i[ui domain infra]

ArchSpec builds the component dependency graph from visible dependency edges and reports cycles such as:

component dependency cycle: domain -> infra -> domain

A group of components that all reach each other is reported once, not once per route through it. When the group is larger than the cycle shown, the message names every component in it and the note carries the shortest cycle to break:

component dependency cycle among 4 components: billing, catalog, orders, shipping

  note: billing -> orders -> billing
