The Go language has a built-in package manager, which is the go command itself.
It’s not a package manager in the same style as npm (JavaScript), pip (Python), or maven (Java), but rather an integrated tool that handles various code-related tasks, including dependency management. Let’s break it down:
✅ What does the go command do regarding packages?
It takes care of tasks such as:
| Task | Command | What it does |
|---|---|---|
| Initialize module | go mod init <module-name> |
Creates the go.mod file and initializes a Go module |
| Add dependency | go get <package> |
Downloads and adds a dependency to go.mod |
| Update dependency | go get -u <package> |
Updates a dependency |
| Install binary | go install <module@version> |
Installs a binary from a remote package |
| View dependencies | go list -m all |
Lists all modules being used |
| Download all deps | go mod tidy |
Downloads and cleans up unused dependencies |
| Compile program | go build |
Compiles the source code |
📦 Where are the packages stored?
By default, Go downloads dependencies to a local cache, usually located at:
~/go/pkg/mod
This directory is managed automatically and should not be modified manually.
⚠️ Is GOPATH still necessary?
In the past, GOPATH was central to package management. However, since Go 1.11 (2018), Go Modules (go.mod) became the standard, and GOPATH is no longer required for modern projects.
