                最近一次项目的总结
              
          
    mathclub是最近做的一个个人项目，帮助考SAT的同学通过在线做题、回顾、问答提高成绩。用户功能有：计次/计时做题、成绩单、错题分布、错题回顾、提问、汇总以及注册登录。管理后台主要是题库管理、学员管理、成绩单管理、问题回复。怎么看都像学校里的课设，的确项目本身并不出奇，开发上选用的一些方案或许更有意思。
整个项目一个人从产品需求、原型设计、前后端开发到部署历时2周左右。可以从截图上感受一下：

技术选型上服务端是Node.js，应用框架选了老牌的Express（4.x变化挺大不少中间件都废了），数据服务用的是MongoLab（MongoDB的云服务平台），图片上传用的是又拍云，程序部署在Nodejitsu上。模板引擎没选主流的Jade或ejs，而是用Express React Views它实现了在服务端渲染React组件。前端框架是用React，这次有意想追求前后端全部组件化的组织。之前是用Webpack实现CommonJS模块打包，这次用Browserify配置更简单，它有丰富的transform很赞，其中的reactify转换React的JSX很完美。CSS用Sass＋autoprefixer让人省心。将这一切串起来的自动构建工具是Gulp。我其实崇尚用最精简的工具组合开发，上述组合在我看来比较精简了。（帖纸留念）

## your-first-report
Note that this is sandbox. If you have not registered profiles in sandbox you
will need to do so prior to making these calls. You will also need at least
one campaign, ad group, and keyword before you see anything in the report.
While in sandbox, we will return “dummy” data so that you can see how an actual
report would look.

To make it look nicer, I always export my access token prior to making calls.
You could do the same for API-Scope (profile Id) if you wish. Make sure to use
quotes around the access token if it isn’t URL encoded. It has a | (pipe)
symbol and your shell won’t like it.
