[Vuejs]-Scroll to anchor on refresh or on manual URL change

I simply used a vue-router navigation guard:

const router = new VueRouter({
    mode: "history",
    base: process.env.BASE_URL,
    routes,

    scrollBehavior (to, from, savedPosition) {
        if (to.hash) {
            this.app.$scrollTo(to.hash, 700);
            return { selector: to.hash }
        } else if (savedPosition) {
            return savedPosition;
        } else {
            //When the route changes, the page should scroll back to the top.
            this.app.$scrollTo('#app', 700);
            return { x: 0, y: 0 }
        }
    }
});

router.afterEach((to, from) => {
    if (to.hash && to.path != from.path)
        Vue.nextTick().then(() => VueScrollTo.scrollTo(to.hash, 700));
});

Unrelated to the question, but related to the navigation with hashes:

If you are publishing your website in GitHub Pages, you’ll need to add these next two parts.

Add a 404.html static page, to redirect the navigation back to the root page, but passing a few parameters in the sessionStorage:

<script>
    const segment = 1;  
    //Gets the relative path and the hash of the URL.  
    sessionStorage.redirect = '/' + location.pathname.slice(1).split('/').slice(segment).join('/');  
    sessionStorage.hash = location.hash;  

    //Forces the navigation back to the main page, since it's the only entry point that works.
    location.replace(location.pathname.split('/').slice(0, 1 + segment).join('/'));
</script>

Alter your main.js page to expect the redirect parameters:

new Vue({
    router,
    i18n,
    render: (h) => h(App),
    created() {
        //If a redirect exists, tell the router.
        if (sessionStorage.redirect) {
            const redirect = sessionStorage.redirect;
            const hash = sessionStorage.hash;
            delete sessionStorage.redirect;
            delete sessionStorage.hash;

            this.$router.push(redirect + hash);
        }
    }
}).$mount("#app");
