Building CLI Tools with Go

Go is an excellent language for building CLI tools. It compiles to a single binary, has great standard library support, and is easy to cross-compile.

Why Go for CLI Tools?

  1. Single binary - No runtime dependencies
  2. Fast startup - Unlike JVM or interpreted languages
  3. Cross-compilation - Build for any OS from any OS
  4. Great libraries - Cobra, Viper, and more

Getting Started

package main

import "fmt"

func main() {
    fmt.Println("Hello, CLI!")
}
  • Cobra - CLI framework used by Kubernetes, Hugo, and GitHub CLI
  • Viper - Configuration management
  • Bubble Tea - TUI framework for rich terminal interfaces

Build something awesome!
