  Node.js是一个Javascript运行环境(runtime)。实际上它是对Google V8引擎进行了封装。V8引 擎执行Javascript的速度非常快,性能非常好。Node.js对一些特殊用例进行了优化,提供了替代的API,使得V8在非浏览器环境下运行得更好。Node.js是一个基于Chrome JavaScript运行时建立的平台, 用于方便地搭建响应速度快、易于扩展的网络应用。Node.js 使用事件驱动, 非阻塞I/O模型而得以轻量和高效,非常适合在分布式设备上运行的数据密集型的实时应用。

  Express 是一个基于 Node.js 平台的极简、灵活的 web 应用开发框架,它提供一系列强大的特性,帮助你创建各种 Web 和移动设备应用。Express 也是官方推荐的Web框架。

  下面介绍一下如何在window环境下跑起来一个网站:

1 安装node.js

2 新建一个文件夹nodejs_express

3 打开cmd ,定位到nodejs_express下

复制代码 代码如下:

E:\myapp\nodejs_express

4 项目初始化 npm init,走完配置后,会在文件夹下生成一个文件:

  package.json

5 安装Express :npm install express,安装成功后,会在文件夹下生成一个node_modules目录

6 Express项目初始化 express (express hello)

7 安装依赖包npm install serve-favicon morgan cookie-parser body-parser path;>npm install jade

更简单的是:

进入项目目录,安装nodejs依赖模块npm install (cd hello ;npm install )

8 启动npm start,并用本地IP的3000端口进行访问

9 端口号可以在bin/www文件中进行修改
