Learning Golang: Dependencies, Modules and How to manage Packages

Welcome! Let's learn about Go Modules! What is a "Go Module"? A module is a collection of Go packages stored in a file tree with a "go.mod" file at its root. This file defines: Module path: indicates how our package will be imported by our users, and Dependency Requirements, indicate the packages we depend on. "Dependency Requirements" not only covers the actual packages but also ways to "Replace" or "Exclude" them, using the corresponding directives: Replace: allows replacing a version of a dependency with another one, for example in cases where local deployment is still happening or when working for forked versions; and Exclude: allows excluding a version of a dependency from use, for example in cases those versions include security issues or bugs. "Go Modules" were introduced in Go 1.11 and enabled by default in Go 1.16, they use "Semantic Versioning" (SemVer) as the main versioning system, were versions are defined using three numbers: Major.Minor.Patch. The Go toolchain allows interacting with Modules via the "mod" command, but not only that other commands like "get" or "build" are also compatible with Go Modules, the most used commands are: "go mod init" to initialize a module, for example "go mod init github.com/MarioCarrion/example-pkg" "go get _package/version_@_specific-version_" go get packages with specific version, for example "go get github.com/jackc/pgx/[email protected]" "go get" can be used to upgrade or downgrade as well, for example to downgrade: "go get github.com/jackc/pgx/[email protected]" or update to latest "go get -u github.com/jackc/pgx/v4" "go mod tidy" to remove unused dependencies. --- "The Go Blog: Using Go Modules" https://blog.golang.org/using-go-modules Real life examples of versioning Go Modules: Using module path: https://github.com/googleapis/gax-go Using branches: https://github.com/olivere/elastic Tools: https://github.com/oligot/go-mod-upgr...
