In this chapter, we described how to implement the major components of a Go web framework. We first designed a router to make up for some of shortcomings in Go's built-in http package, creating a router capable of dynamic routing and REST support. We also designed our own RESTful Controller class in accord with the principles of MVC, borrowing ideas from frameworks such as Tornado. Next, we designed and implemented a template layout and automated rendering system, mainly using Go's built-in templating engine. We then implemented a custom logger and talked about framework configuration to allow for flexible application deployment. Through this process, we have implemented a basic web framework called Beego which, at present, has been open-sourced on Github. Lastly, we implemented a simple blogging application on top of Beego. After having gone through all of these examples, you will hopefully have learned how to quickly develop websites in Go.
