Vue Router is the official client-side router for Vue SPAs. It maps URLs to components and swaps them in without full page reloads, and provides navigation guards to run logic (like auth checks) before navigation.
{ 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
});
Faigheann gardaí to (bealach sprioc) agus from (reatha), agus is féidir leo a ligean ar aghaidh, a chealú (false), nó atreorú (ionad ar ais). Is é an brat meta.requiresAuth + beforeEach domhanda an patrún gréasánaithe auth canónach.
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>
]}
Breis air: paraiméadair bealach, teaghráin fhiosrúcháin, bealaí ainmnithe, iompar scróil, agus comhpháirteanna bealach athlódaithe go mall do roinnt cód.
Tá Vue Router riachtanach do aon SPA Vue illeathanaigh — soláthraíonn sé socrúthú cliant-taobh (tapa, gan athlódú), bealaí dinimiciúil/neadaithe, agus RouterLink/RouterView.
Is iad gardaí socrúthaithe an ghné ríomhaire do imní trasncheanglach: dídacht a chur ar bhealach cosanta de réir auth, amharc a dhéanamh ar leathanaigh, agus dul ar ais ar spréacharnach a bhí gan sábháil.
Is rud é an patrún meta + beforeEach domhanda do fhíordheimhniú rud a chuireann beagnach gach fíorfheidhmchlár i bhfeidhm.
