How to describe an object in swagger, for which we do not exactly know the names of the properties?

Question

API

I get an object of the form: [product name]: DTO with its properties

export class ProductsDto {
  [product: string]: ProductDto
}

export class ProductDto {
  @ApiResponseProperty()
  id: number;

  @ApiResponseProperty()
  price: number;
}

In the output I get an empty object, I use NestJS.

How to do it?

Answer 1

And what prevents you from writing ProductDTO[]instead of creating a separate DTO? This will also work, or better yet, turn it on in the validation configuration in your application to be sure, so to speak. If validation is not enabled in your application, then I advise you to do it globally in the filetransform: true

Only read if you're new to Nest

Вы же не пишете отдельные ValidationPipe для каждого Create эндпоинта?

app.useGlobalPipes(new ValidationPipe({ transform: true }));

Then we easily pull it out in the controller
@Body() productsDto: ProductDto[]
