通过应用生成器工具express可以快速创建一个应用的骨架。通过如下命令安装：

sudonpminstallexpress-generator-g

-h选项可以列出所有可用的命令行选项

express-hUsage:express[options][dir]Options:-h,--helpoutputusageinformation-V,--versionoutputtheversionnumber-e,--ejsaddejsenginesupport(defaultstojade)--hbsaddhandlebarsenginesupport-H,--hoganaddhogan.jsenginesupport-c,--css<engine>addstylesheet<engine>support(less|stylus|compass|sass)(defaultstoplaincss)--gitadd.gitignore-f,--forceforceonnon-emptydirectory

使用express myapp 命令就可以创建一个myapp的应用：

expressmyappcreate:myappcreate:myapp/package.jsoncreate:myapp/app.jscreate:myapp/publiccreate:myapp/public/javascriptscreate:myapp/public/p_w_picpathscreate:myapp/routescreate:myapp/routes/index.jscreate:myapp/routes/users.jscreate:myapp/viewscreate:myapp/views/index.jadecreate:myapp/views/layout.jadecreate:myapp/views/error.jadecreate:myapp/public/stylesheetscreate:myapp/public/stylesheets/style.csscreate:myapp/bincreate:myapp/bin/wwwinstalldependencies:$cdmyapp&&npminstallruntheapp:$DEBUG=myapp:*npmstart

然后安装所有依赖包：

$cdmyapp$npminstall

启动这个应用（MacOS 或 Linux 平台）：

$DEBUG=myappnpmstart

Windows 平台使用如下命令：

>setDEBUG=myapp&npmstart

然后在浏览器中打开http://localhost:3000/网址就可以看到这个应用了。
