Dependency Management¶
We use Go Modules for dependency management. 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.
Organize Dependencies¶
Unfortunately go does not differentiate between dev and test dependencies. It becomes cleaner to organize dev and test dependencies in their respective require clause which gives a clear view on existing set of dependencies. The goal is to keep the dependencies to a minimum and only add a dependency when absolutely required.
Updating Dependencies¶
The Makefile contains a rule called tidy which performs go mod tidy which ensures that the go.mod file matches the source code in the module. It adds any missing module requirements necessary to build the current module’s packages and dependencies, and it removes requirements on modules that don’t provide any relevant packages. It also adds any missing entries to go.sum and removes unnecessary entries.
Warning
Make sure that you test the code after you have updated the dependencies!
