To deploy a Go web application on Apache, we need to understand how the Go language runs a web app. Go uses the net/http package (standard library) for this, which provides implementations for both HTTP clients and HTTP servers.

In this section, we will look at Go modules. It's been a while since GOPATH started being replaced by this new way of managing the dependencies that make up our project. GOPATH is still usable but is becoming obsolete.

Today, we will see how we can integrate C libraries into the Go language when using the Windows operating system.

Go has some predefined environment variables that are frequently used and should be taken into account, as they will be useful in our projects. For example, GOOS will give us the operating system we are on.

If you have been interested in the Gio graphical interface, maybe this is one of the first things you have tried to do. However, as we will see, it is not as easy, and the section that covers this topic is not as comprehensive as we would like. Therefore, we will need to do some further reading to understand how to make separations in this interface.
