intermediate Published 10 May 2026
Action Steps
  1. Identify the domain layer in your NestJS module and define its responsibilities
  2. Separate the use-case layer from the domain layer to encapsulate business logic
  3. Create an infrastructure layer to handle external interactions and dependencies
  4. Implement a presentation layer to handle user input and output
  5. Use an external port to define the module's interface and prevent architectural degradation
