Golang modules

In a nutshell

A module is a collection of Go packages stored in a file tree with a go.mod file at its root.

The go.mod file defines the module’s module path, which is also the import parth for the root directory and its dependency requirements (other modules needed for a successful build).

Create a module

Syntax:

go mod init <prefix>/<module-name>

Example:

go mod init sajadtorkamani/go-playground

This will create a go.mod file with the following content:

module sajadtorkamani/go-playground

go 1.22.6 // or whatever Go version you have

Install a dependency

Syntax:

go get <module>[@version>]

Example:

go get rsc.io/quote 

This will add rsc.io/quote and any of its dependencies to go.mod:

module sajadtorkamani/go-playground

go 1.22.6

require (
	golang.org/x/text v0.0.0-20170915032832-14c0d48ead0c // indirect
	rsc.io/quote v1.5.2 // indirect
	rsc.io/sampler v1.3.0 // indirect
)

List available versions of a module

go list -m -versions <module-name>

Remove unuse dependencies

go mod tidy
