Implementing the RESTful Server
Let’s learn how to implement the RESTful server.
We'll cover the following...
Now that we are sure that the restdb package works as expected, we are ready to explain the implementation of the RESTful server. The server code is split into two files, both belonging to the main package: main.go and handlers.go. The main reason for doing so is to avoid having huge code files to work with and separating the functionality of the server logically.
The main() function
The most important part of main.go, which belongs to the main() function, is the following:
rMux.NotFoundHandler = http.HandlerFunc(DefaultHandler)
First, we need to define the default handler function—although this is not necessary, it is a good practice to have such a handler.
