declare global namespace variable from TypeScript
提问by Olivier Refalo
How to explicitly declare a variable in the global namespace from typescript?
如何在打字稿的全局命名空间中显式声明变量？
I need the compiler to generate the following javascript code:
我需要编译器生成以下 javascript 代码：
MyExtension = someFunction()
unfortunately, I can only have it generate
不幸的是，我只能让它生成
var MyExtension = someFunction()
This comes to an issue with the latest version (still in rc) of meteor packages. Meteor introduced a way to scope namespaces in packages - the issue is, the variable needs to be defined in the global namespace (which meteor reroutes to its own Package object).
这涉及到最新版本（仍在 rc 中）的流星包的问题。Meteor 引入了一种在包中定义命名空间范围的方法——问题是，变量需要在全局命名空间中定义（流星重新路由到它自己的包对象）。
There is a video about it at https://www.eventedmind.com/posts/meteor-linker-package-namespacing.

Is there some kind of globalkeyword available or in the plans?
是否有某种global关键字可用或在计划中？
回答by basarat
Use the declarekeyword. These are known as ambient declarations.
使用declare关键字。这些被称为环境声明。
declare var MyExtentention:any;
