Building Modern CLI Applications in Go

Overview of this book

Although graphical user interfaces (GUIs) are intuitive and user-friendly, nothing beats a command-line interface (CLI) when it comes to productivity. Many organizations settle for a GUI without searching for alternatives that offer better accessibility and functionality. If this describes your organization, then pick up this book and get them to rethink that decision. Building Modern CLI Applications in Go will help you achieve an interface that rivals a GUI in elegance yet surpasses it in high-performance execution. Through its practical, step-by-step approach, you’ll learn everything you need to harness the power and simplicity of the Go language to build CLI applications that revolutionize the way you work. After a primer on CLI standards and Go, you’ll be launched into tool design and proper framework use for true development proficiency. The book then moves on to all things CLI, helping you master everything from arguments and flags to errors and API calls. Later, you’ll dive into the nuances of empathic development so that you can ensure the best UX possible, before you finish up with build tags, cross-compilation, and container-based distribution. By the end of this UX book, you’ll be fully equipped to take the performance and flexibility of your organization’s applications to the next level.

Summary

We’ve gone into the realm of containerization and examined the numerous advantages of utilizing Docker containers for your applications in this chapter. The fundamentals of creating and running a simple Docker image and container are explained, as well as some more sophisticated instances using our audiofile application, which requires the construction of multiple containers that can be composed and run together.

Clearly, utilizing Docker for integration testing boosts your trust in the whole system, and we discussed how to run integration tests using Docker Compose.

At the same time, we’ve acknowledged some of Docker’s drawbacks, such as the increased complexity of maintaining containerized applications, the additional burden of operating several containers on a single host, and the external dependency of Docker itself.

Overall, this chapter has given you a strong knowledge of when to utilize Docker containers for command-line applications—...
