Swagger CLI plugin documentation to include details and examples on using classValidatorShim flag

[sebastiangug]

[x] Documentation issue or request (new chapter/page)

Related to nestjs/swagger#1256

The current documentation on the CLI plugin: https://docs.nestjs.com/openapi/cli-plugin does not contain details or examples around the classValidatorShim flag and how to use it. Can't find any examples of a working version out there either.

I'd be happy to contribute these instructions as soon as I figure out how to get it working for myself, so thought I'd submit this issue here so that I remember to do so and also get some help on getting working from someone.

Thanks.

Any update on this @kamilmysliwiec ? It is mentionned in the other ticket that only @Min, @Max decorators are supported. Many people use the OpenAPI constraints to generate the validation of their front-end forms. Would be nice if there was an easy way to support common validation decorators such as @IsEmail() or '@matches('')'. Right now the only alternative I see is to use @ApiProperty() with a specified type, but this causes a duplication of annotations (class validator and api property) and may cause errors because of the developers mistakes.
