Dependency management

We use golang modules to manage golang dependencies. In order to add a new package dependency to the project, you can perform go get <PACKAGE>@<VERSION> or edit the go.mod file and append the package along with the version you want to use.

Updating dependencies

The Makefile contains a rule called revendor which performs go mod vendor and go mod tidy.

go mod vendor resets the main module’s vendor directory to include all packages needed to build and test all the main module’s packages. It does not include test code for vendored packages.

go mod tidy makes sure go.mod matches the source code in the module. It adds any missing modules necessary to build the current module’s packages and dependencies, and it removes unused modules that don’t provide any relevant packages.

$ make revendor

The dependencies are installed into the vendor folder which should be added to the VCS.

⚠️ Make sure you test the code after you have updated the dependencies!
