Nestjs applyDecorators for multiple decorators

I'd like to create custom decorator with applyDecorators imported from @nestjs/common

...

applyDecorators(
  @Field(),
  @MinLength(2)
)

...

But I got typescript lint errors. How can I create a custom decorator which wraps several decorators?

https://docs.nestjs.com/custom-decorators

"class-validator": "^0.11.0"
"@nestjs/common": "^7.0.9"

You could define a custom decorator method using applyDecorators method.

applyDecorators method accepts PropertyDecorator as arguments. so please make sure to convert them as PropertyDecorator.

export const NameField = (options?: FieldOptions) =>
  applyDecorators(
    Field() as PropertyDecorator, // convert to PropertyDecorator
    MinLength(2) as PropertyDecorator // convert to PropertyDecorator
  )
)
