Packaging, Modules, and Dependency Management 📦

Intermediate

Go encourages modular code organization through packages and modules. To manage dependencies:

Modules

Initialize a module with:

go mod init your_module_name

This creates a go.mod file.

Adding Dependencies

Use go get to add external packages:

go get github.com/some/dependency

The dependencies are tracked in go.mod and go.sum.

Importing Packages

In your code:

import "github.com/some/dependency"

Then, build or run your code, and the dependency is automatically downloaded.

Publishing Modules

To share your package, push your module to a repository (like GitHub), and others can include it via go get.

Managing modules promotes code reuse and easier maintenance, especially in large projects.
