Now, with Go workspaces, we can define a go.work file, specifying to use our local changes, and not have to worry about managing several go.mod files manually ourselves. This is particularly useful when working with larger projects, or projects that span multiple repositories.

Exercise 09.03 – working with workspaces

In this exercise, we will look at what it used to be like when working with projects that had multiple Go modules that needed their dependencies to be replaced so that they could use local changes. We will then update the example code so that it uses Go workspaces to show the improvements:
