安装Express⌗

  • 安装express十分容易
npm install -gd express
  • 执行express，生成MVC的框架
express blog
cd blog
npm install
node app
  • 打开http://127.0.0.1:3000/，你可以看到Express的Hello Word欢迎页面，表示Express已经成功运行。

使用coffee-script开驾驭Express⌗

require "coffee-script"
http = require 'http'
path = require 'path'
express = require 'express'
app = express()
app.configure(->
	app.set('port', process.env.PORT || 3000)
	app.use(express.logger('dev'))
	app.use(express.directory(__dirname + 'public'))
	app.use(express.static(path.join(__dirname, 'public')))
	app.use(express.favicon())
	app.set('views', __dirname + '/views')
	app.set('view engine', 'jade')
	app.use(express.bodyParser({keepExtensions: true, uploadDir: './public/resources'}))
	app.use(express.methodOverride())
	app.use(express.cookieParser())
	app.use(express.session({ secret: 'bang590' }))
	app.use(app.router)
	app.use(express.errorHandler({ dumpExceptions: true, showStack: true }))
	app.enable('trust proxy')
)
  app.get '/', (req, res) ->
  res.send "Hello World!"
  port = process.env.PORT or 3000
  http.createServer(app).listen app.get('port'), ->
  	console.log("Express server listening on port " + app.get('port')
