I\'ve installed a package using go modules (go get in Go 1.13) and now I want to remove it. In the documentation there is nothing about this and in go get docu neither.
Found it https://blog.golang.org/using-go-modules#TOC_7.
go mod tidy
So basically, once the package is not being imported in any package you can perform a go mod tidy
and it will safely remove the unused depencies.
And if you are vendoring the dependencies, then run the command below to make the module changes be applied in the vendor folder:
go mod vendor
