如何将TypeScript类拆分为多个文件？ [英] How do I split a TypeScript class into multiple files?

问题描述

我找到了很多例子，并尝试将模块分成几个文件。所以我得到那个，非常方便。但是出于同样的原因，有时候分割课程也很实际。假设我有几种方法，我不想将所有内容都塞进一个长文件中。

I found a lot of examples and also tried myself to split a module into several files. So I get that one, very handy. But it's also practical sometimes to split a class for the same reason. Say I have a couple of methods and I don't want to cram everything into one long file.

我正在寻找类似于 partial <的东西/ strong> C＃中的声明。

I'm looking for something similar to the partial declaration in C#.

推荐答案

你不能。

有一个功能请求实现了部分类，首先是在 CodePlex 上，稍后是 GitHub ，但在2017-04-04上它被宣布超出范围。给出了很多原因，主要的理由是它们希望尽可能避免偏离ES6：

There was a feature request to implement partial classes, first on CodePlex and later on GitHub, but on 2017-04-04 it was declared out-of-scope. A number of reasons are given, the main takeaway seems to be that they want to avoid deviating from ES6 as much as possible:

TypeScript 已经有太多特定于TS的类功能[...]添加另一个特定于TS的类功能是骆驼背上的另一根稻草，我们应该尽可能避免。 [...]因此，如果某些场景确实将其从公园中推出以添加部分类，那么该场景应该能够通过TC39过程证明自己的合理性。

TypeScript already has too many TS-specific class features [...] Adding yet another TS-specific class feature is another straw on the camel's back that we should avoid if we can. [...] So if there's some scenario that really knocks it out of the park for adding partial classes, then that scenario ought to be able to justify itself through the TC39 process.
