inherited-binding​

Field decorators are also applied to fields declared in parent classes.
This allows you to define common fields in a base class and then extend or override them in child classes.

Example​

class BaseRequest {
  @Body()
  @Length(10)
  id!: string
}

class CreateUserRequest extends BaseRequest {
  @Body()
  @OneOf(["admin", "user"])
  role!: string
}

Result​

CreateUserRequest will have the following fields:

  • id : inherited from BaseRequest

  • role : defined in CreateUserRequest
