help
1

I base on Vue and NProgress to wait the Method Call.

// Check role
                NProgress.start();

                userIsInRole.callPromise({role}).then((result) => {
                    NProgress.done();
                    NProgress.remove();

                   ...............
                }).catch((err) => {

                });

It work fine, but Not Smooth.
(show a little bit bar, and then waiting, final done is very quickly)
Please help me.
