How to implement progressbar in graphQL?

Question

Vue.js

actually that's the whole question. there is a file upload mutation

this.$apollo.mutate({
          variables: {
            file: file
          },
          mutation: gql`mutation($file: Upload) {
            uploadTrack (file: $file){
              id
            }
          }`
        })

I have experience only using fetch, xhr. I have no idea how to do this with apollo and graphQL. share knowledge
