# 13 Build a web framework
# 13 Building a web framework
Preceding twelve chapter describes how to develop Web applications through Go, introduced a lot of basic knowledge, development tools and techniques, then we pass this knowledge in this chapter to implement a simple Web framework. Go language to achieve through a complete frame design, the main contents of this framework, the first section describes the structure of a Web framework planning, such as using the MVC pattern to develop, program execution process design, etc.; second section describes the framework the first feature: Routing, how to get access to the URL mapped to the corresponding processing logic; third section describes the processing logic, how to design a common controller, object inheritance after the handler how to handle response and request; fourth section describes how to framework some auxiliary functions, such as log processing, configuration information, etc.; fifth section describes how to implement a blog-based Web framework, including Bowen published, modify, delete, display a list of other operations.
The Preceding twelve chapters describe how to develop web applications in Go, introducing a lot of basic knowledge, development tools and techniques. In this chapter, we will be using this knowledge to implement a simple web framework. The first section of this chapter will take you through the planning and design stage of building a web framework. We'll look at leveraging the MVC pattern as well as designing program execution flow, among other things. The second section will describe the first feature of our framework: Routing; namely, how to map URLs to processing logic. Then in the third section, we describe the processing logic itself, which involves designing generic controllers, and how to handle requests and return responses after inheriting from an object handler. Next, we describe some of the auxiliary functionality common to most web frameworks, such as log processing, information configuration, etc. Finally, we'll implement a simple blogging system on top of our framework which will demonstrate the application logic necessary for publishing, modifying, deleting, and displaying lists of blog posts.
Through such a complete project example, I expect to be able to allow readers to understand how to develop Web applications, how to build your own directory structure, how to achieve routing, how to achieve the MVC pattern and other aspects of developing content. In the framework prevalent today, MVC is no longer a myth. Many programmers often heard discussions which frame is good, which frame is not good, in fact, the framework is only a tool, there is no good or bad, only suitable or unsuitable, for his is the best, so we write their own framework for the church, then different needs can use their own ideas to be realized.
By seeing first-hand how to implement such a complete project from scratch, you will hopefully have a better understanding of the inner workings of Go web applications. You'll be comfortable building your own project directory structures, implementing URL routers and utilizing MVC, among other aspects of web development. Among the frameworks prevalent today, MVC is no longer a myth. It's not uncommon to hear programmers arguing about which frameworks are good and which are bad, which is often too shallow of an approach. Frameworks are only tools, and some tools are more suitable for certain applications than others. There are no universally good or bad tools. Thus, by teaching yourself how to write a framework from scratch, you will be able to tailor-make the perfect tool to best realize your ideas!
