nestjs-custom-class-validators/src/dto/customValidatorOptions.dto.ts

This package contains a few custom validator I have found to be repetitive, So I made templates that handles both class-validator checks and Swagger configuration

class IDefaultValdationOptions {
  optional?: boolean = false;
  defaultValue?: any;
  description?: string = "";
}

class IBaseValidationOptions extends IDefaultValdationOptions {
  isArray? = false;
}

export class ICustomOnlyDateStringOptions extends IBaseValidationOptions {}

export class ICustomSwaggerOptions extends IBaseValidationOptions {
  type?: "boolean" | "number" | "string" | "array" | "media";
  format?: "binary";
  validEnum?: Object;
}

export class ICustomStringOptions extends IBaseValidationOptions {
  isUUID? = false;
}

export class ICustomTimeValidatorOptions extends IBaseValidationOptions {}

export class ICustomPasswordValidatorOptions extends IDefaultValdationOptions {}

export class ICustomNumberValidationOptions extends IBaseValidationOptions {
  min?: number;
  max?: number;
}

export class ICustomEnumJSONArrayValidatorOptions extends IBaseValidationOptions {
  validEnum?: Object;
}

export class ICustomEnumValidatorOptions extends ICustomEnumJSONArrayValidatorOptions {
  isArray?: boolean = false;
}

export class ICustomBooleanValidatorOptions extends IDefaultValdationOptions {}
