Converting Express 2.x app to Express 3.0 app

I'm currently learning NodeJs and Express am trying to convert a tutorial app from Express 2.5.9 to 3.0. The code below now throws the error "500 Error: Failed to lookup view "views/login". What is the 3.0 way of getting this to render now?

apps
  authentication
    views
      login.jade
    routes.coffee
...
server.js

And in routes.coffee

routes = (app) ->

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

module.exports = routes
