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 from class-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.
