Go manages your project files, and dependencies, and installed binaries in this workspace. go mod why: explains the need for packages or modulesĮarlier projects had to be created inside the $GOPATH, which is an environmental variable that points to the directory where your Go workspace exists before Go Modules were introduced.go mod verify: verifies dependencies have expected content.go mod graph: prints module requirement graph.go mod vendor: this creates a vendored copy of dependencies.go mod download: downloads modules to your device’s cache.go mod tidy: fixes missing modules and removes others who aren’t in use.go mod init: creates a whole new module in the current directory.Automatically check for dependencies when doing build, run, or test.There is no need to install additional tools & software because Go Modules is a built-in function.The Go module can also store dependencies in the vendor directory, allowing different projects to use various versions of the same packages.The package management system resolves dependency versioning concerns, ensures explicit dependency information, and simplifies other dependency management duties. The advent of Go Modules has completely changed the landscape of Golang dependency management. With Go 1.11, Go modules were introduced. Later on, third parties tools like dep and vendoring came along, but the Go language itself had no internal tool to resolve this. It looks a bit odd because, in the case of any major updates in a particular package, there is a high probability that our application would break. go get was the command used to download such dependency in our GOPATH directory. When it comes to Golang, the early versions had no dependency management system. go.sum is a dependency lock file that is generated automatically.īoth files are contained in the project’s root directory.go.mod gives the name of the module, as well as its dependencies and minimum versions.In a Go project, Go Modules introduce two new files: With the help of the Go modules, developers can create projects in any directory of their choice. In the early versions of Go, developers had to add their dependencies in the GOPATH directory. It consists of a collection of Go packages and libraries or projects. Go modules is a built-in dependency versioning and management feature in Go. Version 1.11 added Go modules, a feature to manage the libraries a Go project depends on. Go Modules, like npm in Node.js and pip in Python, are now the default manner of handling dependencies in Golang. Go or Golang, written in C, is an Algorithmic Language with features like Garbage Collection, Memory Safety, Statically Typing, and CSP-Style Concurrent Programming.
