You might be wondering,

“What happens when I install a package with go get|install?”

or

“How do I publish a golang package?

Well, let me introduce you.

First Things First

You need golang. You probably have this. If not, install golang.

The package manager is baked into the go cli, via commands go get and go install, etc.

Summary

Most packages are installed via the go packages registry.

Here are the steps to publish one here:

1. Create a remote repository
2. Create a go package
3. Push your package to the repository
4. Add your package to the go packages registry

Let’s Go!

1. Create a Repository

First, create a repository in GitHub.

2. Create Your go Package

In your repository, create your main.go entrypoint file:

go mod init github.com/$MY_USER/$MY_REPO

touch main.go

In your main.go file:

package main

import "fmt"

func init() {
  fmt.Println("Hello, world")
}

3. Push your Package to the Repository

Add, commit, and push this.

git add .
git commit -m "Init"
git push origin main
git tag v1.0.0
git push origin --tags

4. Add Your Package to the go Packages Registry
