The go get is the utility provided by the standard library for package management. We can install a new package/library by running the following command:
$ go get git-server.com/user-name/library-we-need
This will download and build the source code and then install it as a binary executable (if it can be used as a standalone executable). The go get utility also installs all the dependencies required by the dependency retrieved for our project.
The go get utility is a very simple tool. It will install the latest master commit on the Git repository. For simple projects, this might be enough. However, as projects start growing in size and complexity, keeping track of the version of dependency being used might become critical. Unfortunately, go get is not great for such projects, and we might want to look at other package management tools.
