Packaging, Modules, and Dependency Management 📦
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.
