Summary

In this chapter, we explored the world of Go modules, beginning with an understanding of what modules are and how they provide structured project organization and management of project dependencies. We introduced the two key module files – go.mod and go.sum – that handle dependencies. We also delved into external modules, emphasizing their role in expanding project functionality and their impact on maintainability. We discussed using and consuming multiple modules in a single project, and the concept of Go workspaces for managing multiple modules within a project directory. Hands-on exercises and activities reinforced our understanding.

In the next chapter, we will enhance our module understanding by covering how packages help keep projects more manageable for teams as they iterate, reuse, and maintain projects using packages.
