Summary

Alas, we have come to the end of our CLI project. Over the course of the last four chapters, we have improved the application quite a bit. We also expanded our knowledge of various Crystal concepts in the process. While this is the end of this part of the book, it does not have to be the end of the CLI. Feel free to continue on your own, adding features as you wish. Ultimately, this will help reinforce the concepts introduced along the way.

The next part of the book is going to introduce some new projects focused on web development and will utilize everything you have learned up until now. It will also spend some time demonstrating various design patterns that may come in handy in future projects of yours. So what are you waiting for? First up is learning how to use external Crystal projects, aka shards, as dependencies within your own project. Go get started!
