问题描述
我有一个运行 express.js 的 app.js.
I have an app.js that is running express.js.
我想将代码转换为coffeescript，并考虑创建一个app.coffee，我将其编译为app.js，这样我就可以使用node app.js"运行它.
I wanna convert the code to coffeescript and thought about to create a app.coffee that I compile to app.js so I can run it with "node app.js".
但后来我突然想到，我可以在 app.coffee 中编写该文件并使用coffee app.coffee"运行它.
But then it hit me that I could just write that file in app.coffee and run it with "coffee app.coffee".
这是更好的方法吗?我可以在生产中使用咖啡"运行服务器吗?
Is this a better way? Can I run the server with "coffee" in production?
推荐答案
是的，你可以在生产环境中使用 coffee 命令.我用它.
Yes you can use coffee command in production. I use it.
我可以看到您想要使用 app.js 包装器的两个原因.
I can see two reasons why you would want to use app.js wrapper.
- 您想使用 CoffeeScript 的本地安装.(应用之间的版本不同)
- 您想使用默认的 npm start 来启动您的服务器 :) 请参阅 npm 帮助脚本
- You want to use local installation of CoffeeScript. (different versions between apps)
- You want to use the default npm start to launch your server :) See npm help scripts
哦，你不需要编译它.您可以使用像这样透明地编译咖啡文件的包装器:
Oh, and you don't need compile it. You can use a wrapper like this which compiles the coffee file transparently:
server.js:
require('coffee-script').register();
require("./yourcoffeeapp.coffee");
如果您想在一些不直接支持 CoffeeScript 命令的托管环境中使用 CoffeeScript，这种包装技术特别有用.例如 Cloud 9 IDE.无需摆弄已编译的 js 文件.
This wrapper technique is especially useful if you want to use CoffeeScript in some hosted environments that does not directly support the CoffeeScript command. Such as Cloud 9 IDE. No need to fiddle with compiled js-files.
