Vue Router minangka router resmi sisi-klien kanggo Vue SPA. Pemetaan URL menyang komponen lan ngganti dheweke tanpa reload kaca lengkap, lan nyedhiyakake navigation guard kanggo ngjalanaken logika (kaya cek auth) sadurunge navigasi.
{ createRouter, createWebHistory } ;
routes = [
{ : , : },
{ : , : },
{ : , : (),
: { : } },
];
router = ({ : (), routes });
<template>
<RouterLink to="/users/42">Profile</RouterLink> <!-- declarative navigation -->
<RouterView /> <!-- where the matched component renders -->
</template>
<script setup>
import { useRoute, useRouter } from "vue-router";
const route = useRoute(); // read current route: route.params.id, route.query
const router = useRouter(); // navigate programmatically: router.push("/home")
</script>
// global guard — runs before EVERY navigation (great for auth)
router.beforeEach((to, from) => {
const authed = useAuthStore().isLoggedIn;
if (to.meta.requiresAuth && !authed) {
return "/login"; // redirect: return a path (or false to cancel)
}
// returning true / nothing → allow the navigation
});
Guard nampa to (target route) lan from (saiki), lan bisa ngidini, mbatalake (false), utawa ngalihake (mulihake lokasi). Flag meta.requiresAuth + global beforeEach minangka pola gating auth kanonik.
Global: router.beforeEach / afterEach — every navigation (auth, analytics)
Per-route: beforeEnter in the route config — specific routes
In-component: onBeforeRouteLeave — e.g. "unsaved changes, leave?" prompts
{ path: "/settings", component: Settings, children: [
{ path: "profile", component: Profile }, // → /settings/profile, renders in nested <RouterView>
]}
Plus: param rute, string query, rute ngarang, perilaku scroll, lan komponen rute ngloyot-muat kanggo code splitting.
Vue Router penting kanggo Vue SPA multi-kaca - menehi navigasi sisi-klien (cepet, ora reload), rute dinamis/nested, lan RouterLink/RouterView.
Navigation guard minangka fitur kunci kanggo cross-cutting concerns: gating rute katrangan langsir auth, logging page view, lan nyegah navigasi adoh saka form sing ora diomah.
Pola meta + global beforeEach kanggo autentikasi minangka apa-apa sing meh saben app nyata ngleksanakake.
