创建基础的Egret 项目
创建一个具备Egret UI的效果可以看到效果(比如game) 
egretProperties.json配置:
"modules": [
    {
      "name": "egret"
    },
    {
      "name": "res"
    },
    {
      "name": "tween"
    },
    {
      "name": "promise",
      "path": "./promise"
    }
egret代码变成zip(后缀该为cfg)步骤
- 发布egret项目代码生成,main.min.js文件
 - 压缩egret引擎代码和main.min.js
 
egret.min.js、egret.web.min.js、res.min.js、tween.min.js、main.min.js
压缩egret.zip文件。main.min.js压缩为main.min.js.zip
注意,实际项目中,egret引擎和项目的main的js文件应该分开压成zip,因为引擎代码几乎步变,项目代码经常变动,以后可以只热更项目代码,不动引擎代码zip。
使用的是老版的jszip,因为比较小(70多KB,api会稍微有点不同)
例子是分别使用IntelliJ IDEA和Egret Wing这两个IDE跑的(Egret5.01)
- 压缩文件zip的后缀修改为cfg,主要是zip可能会被下载软件给拦截了。

最终的运行效果,和没有压缩egret代码的效果是一样的。
