[英]Getting a modified type from a class marked by decorator
I have a class defined like:我有一个定义如下的类:
class Person {
@OneToOne()
pet: Animal;
}
Is there a way to get a modified type which looks like this?有没有办法获得看起来像这样的修改类型? (Adding {propertyKey}Id: string
to properties by marking it with a decorator) (将{propertyKey}Id: string
添加到属性中,通过装饰器对其进行标记)
// Using generics
type ModifiedPerson = SomeGeneric<Person>
// Or maybe using functions?
type ModifiedPerson = typeof someFunc(Person);
// Equivalent as:
type ModifiedPerson = {
pet: Animal,
petId: string,
}
What you are asking is not properly possible with typescript today.你问的问题今天用打字稿是不可能的。 There is a pending issue open since 2015 on GitHub .自 2015 年以来在 GitHub 上存在一个未决问题。
@Decorators
have no effect on type. @Decorators
对类型没有影响。
