typescript 的一种引入文件的方式 Triple-Slash Directives

---恢复内容开始---

/// reference 

原文： https://www.typescriptlang.org/docs/handbook/triple-slash-directives.html

The /// <reference path="..." /> directive is the most common of this group. It serves as a declaration of dependency between files.

Triple-slash references instruct the compiler to include additional files in the compilation process.

They also serve as a method to order the output when using --out or --outFile. Files are emitted to the output file location in the same order as the input after preprocessing pass.

 

log.ts

?

1 2 3

function logMsg(){     console.log('logMsg'); }

main.ts

?

1 2	///<reference path="./log.ts" /> logMsg();

编译出来的结果：out.js的内容为

?

1 2 3 4 5

function logMsg() {     console.log('logMsg'); } ///<reference path="./log.ts" /> logMsg();
