nestjs core module guidelines

When reviewing or writing code, apply these guidelines:

• Global filters for exception handling.
• Global middlewares for request management.
• Guards for permission management.
• Interceptors for request management.

nestjs general guidelines

When reviewing or writing code, apply these guidelines:

• Use modular architecture
• Encapsulate the API in modules.
  • One module per main domain/route.
  • One controller for its route.
  • And other controllers for secondary routes.
  • A models folder with data types.
  • DTOs validated with class-validator for inputs.
  • Declare simple types for outputs.
  • A services module with business logic and persistence.
  • One service per entity.
• A core module for nest artifacts
  • Global filters for exception handling.
  • Global middlewares for request management.
  • Guards for permission management.
  • Interceptors for request management.
• A shared module for services shared between modules.

  • Shared business logic
• Use the standard Jest framework for testing.
• Write tests for each controller and service.
• Write end to end tests for each api module.
• Add a admin/test method to each controller as a smoke test.
