问题描述
在以下视频中35:00左右Anders Hejlsberg谈论外部模块时...
When Anders Hejlsberg is talking about external modules around 35:00 in the following video...
...为什么文件server.ts需要对node.d.ts的三斜杠引用，而hello.ts不需要对server.ts的相似引用?
... why does the file server.ts require a triple slash reference to node.d.ts where as hello.ts doesn't require a similar reference to server.ts?
尤其是在hello.ts中，他提到存在智能感知，并且可以使用从server.ts导出的项目.那么，三斜杠参考还能添加什么呢?
In particular in hello.ts he mentions that intellisense is present plus he gets to use the exported item from server.ts. So what more could the triple slash reference add?
推荐答案
在两种情况下，您需要三斜杠引用:
You need a triple slash reference in two scenarios:
- 在引用JavaScript类型定义时，例如大量收集的关于节点，jquery等的定义，请参见: https://github.com/borisyankov/DefinitelyTyped
- 当我们要使用
--out进行编译时，可以使用/// <reference引用文件.
- When you are referencing JavaScript type definitions e.g. definitions for node, jquery etc. for a great collection see : https://github.com/borisyankov/DefinitelyTyped
- When we want to compile using
--outyou can reference your files using/// <reference.
使用外部模块(即amd/commonjs)时，需要一个import/require组合键.如果您不知道这些含义是什么(amd/commonjs是javascript术语，不是特定于打字稿的)，则不必担心.只需使用/// <reference并使用--out进行编译.
You need a import/require combo when using external modules i.e. amd/commonjs. If you don't know what these mean (amd/commonjs are javascript terms, not specific to typescript) you don't have to care. Just use /// <reference and compile with --out.

对于新项目，请使用tsconfig.json代替参考注释: http://basarat.gitbooks.io/typescript/content/docs/project/compilation-context.html
Please use tsconfig.json for new projects instead of reference comments : http://basarat.gitbooks.io/typescript/content/docs/project/compilation-context.html
