javascript - Coffeescript: How to import express module in one line -

currently, have write

app = require 'express' app()

to equivalent javascript:

var app;   app = require('express'); app();

how can in 1 line?

i want clear thing here.

first of all, here common way import express module , create application:

express = require 'express' app = express()

app variable here holds freshly created express application, while express variable holds framework itself.

now, let's don't need express framework here, application. in case write:

app = require 'express'

and if don't need variable holding application, write that:

do express = require 'express'

though can't imagine why want it. of course, chain everything:

do express = require 'express'   .use(express.static('public'))   .listen(3000)

but me looks mess.
