A simple example repository showing how package versioning works with Go.

Example of how Package Versions Can Work in Go

Notice the following:

  • The greeting package is called greeting in both the v1 and v2 directories.
  • The greeting package is NOT called v1 or v2 like how it is in this Kubernetes example.
  • Note that I have a single go.mod file in the root directory, where main.go is.
  • The first line in the go.mod file is module github.com/codegold79/simple-versioning-with-go. That sets the namespace for all the packages in the repo.
  • I ran go mod tidy to bring in dependencies (probably not needed, but good practice).
  • Run go run main.go and see that I can use whatever package I imported using greeting.

Try it out yourself. Change the import path to V2 and see the greeting change. You didn't need to reset all the imported package aliases and update them all in the code.
