有次在克隆github项目的时候突然想知道项目有多大，发现好像没有什么直接的方式的可以看到，搜索了一番主要有两种方式：安装浏览器插件，使用GitHub API
- 安装浏览器插件
- Chrome插件：https://github.com/harshjv/github-repo-size
图片来自该gitnub项目的介绍
- Firefox插件：https://addons.mozilla.org/en-US/firefox/addon/github-repo-size/
- 使用GitHub API
直接在浏览器地址栏输入https://api.github.com/repos/organization/repository
其中organization替换为项目的所有者(组织)，repository替换为项目的名称`
返回的页面是描述这个项目的JSON数据，其中的size指的就是项目的大小，单位为kB(千字节)
git组织的git项目：https://api.github.com/repos/git/git
北京大学的gStore项目：https://api.github.com/repos/pkumod/gStore

总结
使用浏览器插件更直观更方便，只需要安装插件
使用GitHub API的方式更简单，有人可能不喜欢安装那么多插件，比如我，不过需要稍微记一下格式
