Clean Architecture — Layers That Make Sense
Master the dependency rule, understand architectural layers, and see how Clean Architecture maps to real Next.js applications.
Robert Martin's Clean Architecture gets a bad reputation. Not because the ideas are wrong, but because most explanations turn it into an academic exercise with UML diagrams that nobody translates into real code. The core insight is powerful and practical: dependencies should point inward, toward your business logic, not outward toward frameworks and databases.
This lesson strips Clean Architecture down to its essential principle and shows you how to apply it in a modern web application.
The One Rule That Matters
Clean Architecture has one rule that matters above all others: the Dependency Rule.
