Maintain Module Dependencies

The go mod tidy command allows us to add missing dependencies or delete unused modules. This go command helps in maintaining module dependencies and keep your applications as lean as possible. Simply run the following simple command to do this.

Make sure to run this from your project’s root directory. You can check the go.mod file to see which dependencies were added or deleted. The -v flag, if used, causes tidy to display which modules were removed to the standard error.

go mod tidy [-v]

Verify Module Dependencies

go mod verify

go mod why [-m] [-vendor] packages...
go mod why
