What are the package managers in Go language?

With the increasing popularity of Go language, more and more developers are beginning to invest in this field. Of course, when we use Go, we will definitely involve the use of some packages. Then, in the process of using these packages, we will use some package managers. So, what are the package managers in the Go language? This article will introduce it to you.

First of all, what we need to understand is that for the Go language, the officially recommended package management tool is go mod. This tool was first introduced in Go 1.11. It supports downloading and caching code from different code repositories (such as GitHub, BitBucket, and GitLab), can generate go.sum files to verify the integrity and security of the code, can clear the cache, and also supports the processing of private warehouses and vendor directories. Using it, we can easily import dependencies for a project without having to manage them manually. For example, we can add a dependency by executing the following command:

go mod tidy

This command will read the dependency from the code and then update the contents of the go.mod file. It is worth mentioning that go mod also supports proxies, which can be configured to increase download speeds.

In addition to the officially recommended go mod, there are also some third-party package managers, such as dep, godep, govendor, etc. Below, we will introduce these package managers one by one.

dep: dep is a package manager developed by the Go community. Its functions are similar to go mod. It declares dependencies for your project and provides tools similar to go get to download them.

godep: godep is another commonly used package manager that has become increasingly popular with the development of the Go language. It provides a set of commands to manage dependencies, simplifying the code distribution process.

govendor: govendor is another popular package manager that allows you to download code from different code repositories and cache them. It can also generate vendor directories for your project, allowing you to easily share code.

In general, when we develop in Go language, it is best to use the officially recommended package manager go mod. It's fully functional and easy to use. Of course, if you are more familiar with some other package managers, you can choose to use them as well. With the help of these package managers, we can manage our dependencies more conveniently and improve development efficiency.
