overnightjs 提供了基于注解的expressjs应用开发，包含了比较全的express 开发支持，使用简单，以下是一个简单的试用
项目使用pkg 进行了打包处理
yarn init -y
yarn add @overnightjs/core @overnightjs/logger express http-status-codes
yarn add @types/express pkg typescript --dev

使用overnightjs 开发express 应用还是很方便的，当然 routing-controllers 也是一个不错的选择（更新还很频繁），而且typestack 团队开发
的好多typescript 的框架也是很好用的。
