Go modules and dependency management

Go modules are the dependency management system for the Go programming language, introduced to handle external libraries and define the root of an application's code structure.^[400-devops__09-Scripting-Language__golang__introduction__part-5.database.redis__readme.md]

Module Initialization

A Go module is initialized using the go mod init command, which creates a go.mod file in the current directory^[400-devops__09-Scripting-Language__golang__introduction__part-5.database.redis__readme.md]. The command typically accepts a module path (e.g., the directory name) as an argument^[400-devops__09-Scripting-Language__golang__introduction__part-5.database.redis__readme.md].

Dependency Management

Go manages dependencies through the go get command.^[400-devops__09-Scripting-Language__golang__introduction__part-5.database.redis__readme.md] This command downloads the specified package and adds it to the module's requirements.

For example, to integrate the Redis client library into a project, the following command is used^[400-devops__09-Scripting-Language__golang__introduction__part-5.database.redis__readme.md]:

go get github.com/go-redis/redis/v8

Once a package is fetched via go get, it can be imported and utilized within the application code^[400-devops__09-Scripting-Language__golang__introduction__part-5.database.redis__readme.md].
