@nestjs/swagger/plugin requires at least one decorator in the class to generate ApiProperty automatically

Bug Report

Current behavior

Swagger module need at least one decorator in a class to correctly decorate classes with @nestjs/swagger/plugin

Step to reproduce

Take the default E2E sample (cats) provided in @nestjs/swagger/plugin. Remove all class-validator decorators.

export class CreateCatDto {
  readonly name: string;

  readonly age: number;

  readonly breed: string;
}

Expected behavior

Should add ApiProperty automatically to all fields. When no decorator is provided at all NestJS doesn’t decorate the class.

Possible Solution/Workaround

Add one fake decorator on any field 😃

Environment

Nest version: 6.10.5 “nestjs/swagger”: “4.0.2”,

For Tooling issues:

• Node version: latest
• Platform: Windows
