用于多个装饰器的Nestjs applyDecorators

我想使用从

@nestjs/common

...

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

...

但我有打字稿的线头错误。如何创建一个包含多个decorator的自定义decorator

---

您可以使用

applyDecorators

方法定义自定义装饰器方法

applyDecorators

方法接受

PropertyDecorator

作为参数。因此，请确保将它们转换为

PropertyCorator

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

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