require()'ing a CoffeeScript file from a JavaScript file or REPL
提问by nicolaskruchten
I'm using Node.js and wanting to incorporate CoffeeScript into my workflow. I have two use-cases:
我正在使用 Node.js 并希望将 CoffeeScript 合并到我的工作流程中。我有两个用例：
- I want to be able to write JavaScript files which
require()CoffeeScript modules - I want to be able to load CoffeeScript modules from within the node REPL
- 我希望能够编写包含
require()CoffeeScript 模块的JavaScript 文件 - 我希望能够从节点 REPL 中加载 CoffeeScript 模块
For case #1:I can just compile from .coffeeto .jsand require()the .jsmodule, as a workaround.
对于情况＃1：我可以从编译.coffee到.js与require()该.js模块，作为一种解决方法。
For case #2:Right now I'm eval()ing the output of coffee-script.compile().
对于案例#2：现在我正在eval()输出coffee-script.compile().
Is there a better, more unified way to do this?
有没有更好、更统一的方法来做到这一点？

The coffee-scriptmodule registers its extension once required.
一旦需要，coffee-script模块会注册其扩展名。
$ echo 'console.log "works"' > module.coffee
$ echo '
> require("coffee-script")
> require("./module")
> ' > test.js
$ node test.js
works
$ node
> require('coffee-script'); require('./module')
works
{}
Edit: This behaviour has changed with the relase of CoffeeScript 1.7.0. Now you need to do:
编辑：此行为已随着 CoffeeScript 1.7.0 的发布而改变。现在你需要做：
require('coffee-script/register');

A more versatile solution would be to use better-require.
一个更通用的解决方案是使用better-require。
npm install better-require
It lets you require()CoffeeScript files, no pre-compilation needed. (It also lets you require()a bunch of other file formats: CoffeeScript, clojurescript, yaml, xml, etc.)
它可以让您使用require()CoffeeScript 文件，无需预编译。（它还允许您require()使用一堆其他文件格式：CoffeeScript、clojurescript、yaml、xml 等）
In the case of CoffeeScript, it simply requires the coffee-scriptmodule.
在 CoffeeScript 的情况下，它只需要coffee-script模块。
require('better-require')();
var myModule = require('./mymodule.coffee');
var clojurescriptModule = require('./mymodule.cljs');
// etc.
Disclosure:I wrote better-require.
披露：我写了better-require。
