Wrapping Up
Powerful Command-Line Applications in Go — by Ricardo Gerardi (83 / 127)
👈 Exercises | TOC | Chapter 8 Talking to REST APIs 👉
You used Cobra to create a command-line application that looks professional. Your application includes detailed help and usage information, POSIX-compatible flags, configuration files, command completion, and documentation. You also used the Cobra generator to create the boilerplate code for these features allowing you to focus on your business logic to create a functional TCP port scanner for your network.
In the next chapter, you’ll use Cobra again to develop a command-line application that connects to web services using the REST standard.
