Use TypeScript compiler from node
提问by Ilia Choly
It's pretty easy to do this with coffee-script.
使用咖啡脚本很容易做到这一点。
var coffee = require('coffee-script');
coffee.compile("a = 1");
//=> '(function() {\n var a;\n\n a = 1;\n\n}).call(this);\n'
Is there a way to do this with typescript?
有没有办法用打字稿做到这一点？
Edit:also posted on codeplex

It seems that nowadays there is a simpler solution, you can do:
现在似乎有一个更简单的解决方案，您可以这样做：
let ts = require('typescript');
let source = ts.transpileModule('class Test {}', {}).outputText;
This results in:
这导致：
"use strict";
var Test = (function () {
function Test() {
}
return Test;
}());

Since TypeScript's NPM module doesn't export any public interface, the only way to do this currently is to execute the tscprocess.
由于 TypeScript 的 NPM 模块不导出任何公共接口，因此目前执行此操作的唯一方法是执行该tsc过程。
var exec = require('child_process').exec;
var child = exec('tsc main.ts',
function(error, stdout, stderr) {
console.log('stdout: ' + stdout);
console.log('stderr: ' + stderr);
if (error !== null) {
console.log('exec error: ' + error);
}
});
An issuehas been opened to request a public interface for the TypeScript module.
已打开一个问题来请求TypeScript 模块的公共接口。

better-requirecould help you achieve this.
Better-require可以帮助您实现这一目标。
It lets you require() typescript files - no pre-compilation needed - and a bunch of other file formats (coffeescript, clojurescript, yaml, xml, etc.)
它允许您使用 require() 打字稿文件 - 无需预编译 - 以及一堆其他文件格式（coffeescript、clojurescript、yaml、xml 等）
require('better-require')();
var myModule = require('./mymodule.ts');
Disclosure: I wrote better-require.
披露：我写了更好的要求。

Check this github projectby niutech, it can convert TypeScript code to JS code on the fly in browser, but I guess it can be easily be modified to work in node.js.
检查niutech的这个github项目，它可以在浏览器中即时将TypeScript代码转换为JS代码，但我想它可以很容易地修改为在node.js中工作。
I found it while I'm investigating the possibility of support TypeScript in my live, firebug-inspired code editor.

Not answering the question directly, but since Googling for "run TypeScript from node directly" brings up this StackOverflow page, I figure I should add that you're able to do this with ts-node: https://github.com/TypeStrong/ts-node
没有直接回答这个问题，但由于谷歌搜索“直接从节点运行 TypeScript”会出现这个 StackOverflow 页面，我想我应该补充一点，你可以使用 ts-node 来做到这一点：https: //github.com/TypeStrong /ts-节点

(the later doesn't answer the original question but is very common to access /modify the AST and then transpile to object language so it could be usefull)
（后者没有回答原始问题，但访问/修改 AST 然后转换为对象语言非常常见，因此它可能很有用）
