继承带有导出的类和模块的TypeScript [英] Inheritance TypeScript with exported class and modules

问题描述

我对使用打字稿的继承感到疯狂。我不知道为什么，但它无法解析我想继承的类。

I'm getting crazy with inheritance using typescript. I don't know why but it cannot resolve the class I want to inherit.

lib / classes / Message.class。 ts

lib/classes/Message.class.ts

///<reference path='./def/lib.d.ts'/>
///<reference path='./def/node.d.ts'/>

export module SharedCommunication {
    export class Message{
         // Stuff
    }
}

lib / classes / ValidatorMessage.class。 ts

lib/classes/ValidatorMessage.class.ts

///<reference path='./def/lib.d.ts'/>
///<reference path='./def/node.d.ts'/>
///<reference path='Message.class.ts'/>

export module SharedCommunication { 
    export class ValidatorMessage extends Message{
        private  _errors;
    }    
}

无法解析消息。我也尝试过SharedCommunication.Message，但它是一样的。我引用了课程，所以我根本不明白发生了什么。你有什么想法吗？

Message cannot be resolved. I tried SharedCommunication.Message too but it's the same. I reference the class so I don't understand at all what's going on. Do you have any idea?

我试过没有模块（两个类没有任何模块），但它是一样的。我需要导出类（以及模块，如果我使用它）从另一个node_module：typescript.api获取它们，我用它来加载类并在节点中使用它。

I tried without the module (two class without be in any module) but it's the same. I need to export the class (and the module if I use it) to get them from another node_module: typescript.api, which I use to load the class and use it in node.

lib / message.js

var Message = require('./classes/Message.class.ts');

module.exports = Message.SharedCommunication.Message;

这里的诀窍是什么？因为我在使用继承的不同文件夹中的同一项目上有源代码，没有模块或导出。谢谢。

What's the trick here? Because I have source code on the same project in a different folder working with inheritance, without module or export. Thanks.

推荐答案

ValidatorMessage.class.ts应如下所示：

ValidatorMessage.class.ts should look like this:

///<reference path='./def/lib.d.ts'/>
///<reference path='./def/node.d.ts'/>

import message = require('./Message.class');

export module SharedCommunication { 
    export class ValidatorMessage extends message.SharedCommunication.Message {
        private  _errors;
    }
}

单个<$ c $通常是多余的c>导出模块位于文件的顶层，因为文件本身无论如何都构成了一个命名空间。

It's usually redundant to have a single export module at the top level of a file since the file itself constitutes a namespace anyway.

Bill在你的另一个问题中提到了这一点，但是如果你刚开始使用TypeScript，我会再次提醒使用RequireTS - 这听起来很不成熟，很可能引起很多混乱。

Bill mentioned this in your other question, but I'd again caution on using RequireTS if you're just starting out with TypeScript - it sounds pretty unmature and is likely to introduce a lot of confusion.
