node.jsでexpress使うんだったらcoffeescriptでもいいかなと思った瞬間

この書き方だとyaml(設定ファイル)っぽくて読みやすいですね。※簡単なブログを想定。

setRoutes = (routes) ->
  for own routeName, route of routes
    for own method of route
      app[method] routeName, route[method]


setRoutes
  '/admin*':
    all: auth.ensureAuthenticated(failureRedirect: '/login')


setRoutes
  '/':
    get: (req, res) ->
      res.send req.query.page

  '/entry/:name':
    get: (req, res) ->
      res.send req.params.name

  '/tag/:name':
    get: (req, res) ->
      res.send req.params.name

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

    post: auth.authenticate
      successRedirect: '/admin'
      failureRedirect: '/login'

  '/logout':
    get: (req, res) ->
      req.logout()
      res.redirect '/login'

  '/admin':
    get: (req, res) ->
      res.send 'admin page!'


  '/admin/entries':
    get: (req, res) ->
      res.send 'admin entries page!'

  '/admin/entry/:id':
    get: (req, res) ->
      res.send 'hello'

    post: (req, res) ->
      res.send 'hello'

    put: (req, res) ->
      res.send 'hello'

    delete: (req, res) ->
      res.send 'hello'
