Day 9: Structuring Go Projects and Modules

Introduction:

Go modules for dependency management. Project structure (main.go, go.mod, utility packages). Best practices for organizing Go code.

Code Example: Simple Module

myproject/
├── go.mod
├── main.go
└── utils/
    └── network.go

myproject/go.mod:

module example.com/myproject

go 1.22

myproject/utils/network.go:

package utils

import "fmt"

func GreetNetworkEngineer(name string) {
    fmt.Printf("Hello, %s! Happy automating!\n", name)
}

myproject/main.go:

package main

import (
    "example.com/myproject/utils" // Import your custom package
    "fmt"
)

func main() {
    fmt.Println("Starting network automation project.")
    utils.GreetNetworkEngineer("Alice")
}

• To run: cd myproject && go mod tidy && go run .

Challenge 9:

Refactor your configureInterface function from Day 4 into a config package within your project. Update main.go to import and use it.
