Stop the Spaghetti: Enforcing Module Boundaries in an Nx Monorepo

Enforcing Module Boundaries in an Nx Monorepo It starts with good intentions. Your team decides to adopt a monorepo. You scaffold your workspace, create a handful of libraries, and for the first few sprints everything feels clean and purposeful. Then the deadlines hit. A developer needs a formatting utility from the payments module — so they reach in and import it directly. Another engineer needs a component from the loans feature for a quick prototype in the accounts section. Someone else, pressed for time, imports a service three layers deep from another domain's internals. Nobody reviews it too carefully. The CI pipeline is green. Ship it. Six months later, your dependency graph looks like a bowl of spaghetti. The payments domain knows about accounts. The accounts feature imports from loans. Shared utilities carry domain-specific logic. Nobody can confidently change anything without triggering a cascade of broken imports across the workspace. Your architecture diagram, proudly mount
