scrollbehavior savedposition - how does it work?

pureblood

Hey guys,
coming from angular/ionic I am having a little trouble to understand the right setup.

By default my quasar apps behave like this:

create a popstate navigation
open a page and scroll far down
navigate forward (popstate) and hit browsers back button
end up on previous page but at top not as (expected) scrolled Position

I tried a few things so far like:

quasar.conf.js activating vueRouterMode: ‘history’,
changed router/index.js to:

  const Router = new VueRouter({
    //scrollBehavior: () => ({ x: 0, y: 0 }),
    scrollBehavior: (to, from, savedPosition) => new Promise((resolve) => {
      const position = savedPosition || {};
      if (!savedPosition) {
        if (to.hash) {
          position.selector = to.hash;
        }
        if (to.matched.some((m) => m.meta.scrollToTop)) {
          position.x = 0;
          position.y = 0;
        }
      }
      Router.app.$root.$once('triggerScroll', () => {
        Router.app.$nextTick(() => resolve(position));
      });
    }),

    routes,

sadly those two did not do the trick. I am pretty sure that is a basic misunderstanding in regards to vue on my end.
Anyone able to help me get back on track?

@pureblood When ever possible I use Vue’s <keep-alive>.

<q-page-container id="main-page-container">
        <transition enter-active-class="animated fadeIn">
            <keep-alive>
                <router-view>

                </router-view>
            </keep-alive>
        </transition>
    </q-page-container>

This way the components are not recreated every time you navigate to them and retain their scroll position. I am not sure if it is the correct way mind but for me it works. In fact I wonder why this is not the default behaviour … maybe others can explain?
