I am working with the following code snippet:
export class DocumentsSteps {
@ApiProperty({type: ???})
[type: string]: DocumentStep;
}
Can anyone help me determine how to define the type for ApiProperty?

To enhance its functionality, you can encase it within a function.
export type Constructor<I> = new (...args: any[]) => I
function ErrorDto(statusCode: number, message: string): Constructor<Error>{
class Error implements Error{
@ApiProperty({ example: statusCode })
readonly statusCode: number
@ApiProperty({ example: message })
readonly message: string
}
return Error
}
export class UnauthorizedErrorDto extends ErrorDto(401, 'Unauthorized'){}
export class BadRequestErrorDto extends ErrorDto(400, 'Bad Request'){}
Currently, as of September 21, 2021, the Nest @nestjs/swagger library does not support using dictionaries due to the lack of a metadata field. However, there is a possibility to contribute by opening a pull request on the GitHub repository to enable dictionary usage with the library. In the meantime, the workaround would be to manually modify the generated swagger document from Nest and incorporate the required functionality.
I have discovered a solution for this issue, although it may appear somewhat messy in swagger, it is indeed the most effective method.
By utilizing additionalProperties, you can incorporate dynamic keys with a typed value by referencing your Dto.
The Dto will remain separate from any other response and might not show up in swagger; to make it visible, we must utilize @ApiExtraModels()
@ApiExtraModels(DocumentStep)
export class DocumentsSteps {
@ApiProperty({
additionalProperties: { oneOf: [{ $ref: getSchemaPath(DocumentStep) }] },
})
[type: string]: DocumentStep;
}
The end result will resemble something like this https://i.sstatic.net/k3WrX.png

You have the option to create a new decorator that enhances the functionality of ApiProperty
export function EnhancedApiProperty(type: string) {
return applyDecorators(
ApiProperty({type, ...}),
);
}
