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.
- Utilities
- 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.
