NestJS Support

archlint understands the modular architecture of NestJS and provides specialized analysis for it.

Key Features

• Module Analysis: Recognizes @Module as a coordination point and relaxes coupling rules for it.
• Entry Points: Automatically marks Controllers and Providers as entry points.
• Layer Enforcement: Works perfectly with NestJS-style layer architectures (Controllers -> Services -> Repositories).
• LCOM Overrides: Ignores NestJS decorators in cohesion analysis to focus on the actual logic.
