从命名空间重新导出 Typescript 枚举? [英] re-export Typescript enum from namespace?

问题描述

我在模块some-lib"中有一个枚举定义.我想从我的模块中的命名空间重新导出它，如下所示:

I have an enum definition in module 'some-lib'. I want to re-export it from a namespace in my module, something like this:

import { PaymentType } from 'some-lib';

namespace Payout {
    export enum PaymentType = PaymentType;
}

我没有任何运气.我想这样做是为了给枚举取别名并将其放入不同的命名空间中，以避免与具有相同名称的其他类型发生冲突.我不想在我的代码中定义枚举的重复副本，并且必须维护所有枚举值.

I'm not having any luck. I want to do this in order to alias the enum and put it into a different namespace to avoid collisions with other types with the same name. I don't want to have to define a duplicate copy of the enum in my code, and have to maintain all the enum values.

Typescript 目前有什么办法支持这个吗?

Is there any way Typescript supports this currently?

推荐答案

是的，有一种方法可以做到这一点，例如:

Yes, there's a way to do this, e.g.:

import { PaymentType as _PaymentType } from 'some-lib';


namespace Payout {
  export import PaymentType = _PaymentType;
}

或者:

import * as SomeLibTypes from 'some-lib';


namespace Payout {
  export import PaymentType = SomeLibTypes.PaymentType;
}
