Question

在关注使用Coffeescript和Node.js的书籍示例时，我正在尝试在routes.coffee文件中定义路由，如下所示：

routes = (app) ->


app.get '/login', (req,res) ->

    res.render "views/login",

        title: 'Login'

        stylesheet: 'login'

module.exports = routes

将app对象传递给主启动文件应用程序中的routes.coffee（或者它应该）。：

require('./routes')(app);

尝试启动应用程序（节点应用程序）时出现以下错误：

/Users/eugene/Documents/DevTraining/MeanStack/NodeJS/HotPie/routes.coffee:6

  app.get('/login', function(req, res) {
  ^
ReferenceError: app is not defined

  at Function.Module.runMain (module.js:497:10)

请问这项工作的正确方法是什么？

好吧，看来，在稍微弄乱了缩进后，app对象被识别出来了：
routes =（app） - ＆gt;

 app.get '/login', (req,res) ->
     res.render "views/login",
        title: 'Login'
        stylesheet: 'login'

module.exports = routes

如何将应用程序对象从app。正确传递到Node应用程序中的routes.coffee
