The first girlfriend -- AngularJS

The firtst girlfriend – AngularJS

前言:

• Angular是如何在本地能够跑起来的项目, 它是基于什么跑起来的项目, 这都是需要深入了解的。

http-server:

• http-server:
  

  • 简单的http-sever;
  • NodeJS的HTTP接口;
  • 安装:npm install http-server;
  • 简单介绍:
    
    • http-server 是一个简单的零配置命令行HTTP服务器, 基于 nodeJs.
    • 如果你不想重复的写 nodeJs 的 web-server.js, 则可以使用这个.
  • http-sever: Windows下的使用
    
    • 访问:http://localhost:8080 or http://127.0.0.1:8080;你就可以看到你想看到的景象.
    • 使用package.json: "scripts": {"start":"http-server -a 0.0.0.0 -p 8000",}；
    • 到这里就配置的差不多了, 所以说是简单的http-server.

package.json:

• package.json配置参数:

-p 端口号 (默认 8080)-a IP 地址 (默认 0.0.0.0)-d 显示目录列表 (默认 'True')-i 显示 autoIndex (默认 'True')-e or --ext 如果没有提供默认的文件扩展名(默认 'html')-s or --silent 禁止日志信息输出--cors 启用 CORS via the Access-Control-Allow-Origin header-o 在开始服务后打开浏览器-c 为 cache-control max-age header 设置Cache time(秒) , e.g. -c10 for 10 seconds (defaults to '3600'). 禁用 caching, 则使用 -c-1.-U 或 --utc 使用UTC time 格式化log消息-P or --proxy Proxies all requests which can't be resolved locally to the given url. e.g.: -P http://someurl.com-S or --ssl 启用 https-C or --cert ssl cert 文件路径 (default: cert.pem)-K or --key Path to ssl key file (default: key.pem).-r or --robots Provide a /robots.txt (whose content defaults to 'User-agent: *\nDisallow: /')-h or --help 打印以上列表并退出

Big-man的package.json:

• 比如Big-man的package.json:
