Documenting a Generic Create DTO
This document describes the purpose and structure of a generic Create DTO (Data Transfer Object) used within a NestJS application.
Purpose:
- Defines the expected data structure for creating a new resource within the application.
- Enforces data validation and sanitization before submitting data to the service layer.
- Promotes consistent data handling and API interaction.
Key Elements:
- Import:
ApiProperty
from@nestjs/swagger
for generating API documentation (optional).
- Validation:
Is<X>
decorators fromclass-validator
for enforcing data type and presence validation (customizable).
- Properties:
- Each property represents a field required for creating a new resource.
- Property names and types should align with the underlying resource entity attributes.
ApiProperty
decorator (optional) provides descriptions for API documentation.
Benefits:
- Improves data integrity and security by validating incoming data.
- Simplifies service implementation by ensuring data is received in the expected format.
- Enhances API clarity and documentation with property descriptions.
Additional Notes:
- The specific properties, validation rules, and API descriptions will vary depending on the actual resource type and application requirements.
- Consider using more specific validation decorators like
IsEmail
,IsNumber
, or custom validation functions as needed. - This is a generic overview, and you might need to adjust it to reflect the specific details of your DTO.
