Optimisasi performans Vue nyakup ukuran bundle, efisiensi rendering, lan biaya reactivity. Kene teknik-teknik sing paling berpengaruh.
1. Code splitting / lazy loading

Kabeh keuntungan loading awal sing paling gedhé: aja ngirim kode sing durung dibutuhake dening user.
<div v-show="tab === 'a'"> <!-- toggled often → cheap CSS flip -->
<div v-if="rarelyShown"> <!-- rarely rendered → skip building it -->
<li v-for="item in items" :key="item.id"> <!-- enables efficient DOM reuse/diffing -->
import { shallowRef, shallowReactive } from "vue";
// for large objects you replace wholesale (or 3rd-party instances), skip deep tracking
const bigData = shallowRef(hugeObject); // only .value reassignment is reactive
Object.freeze(staticConfig); // never-changing data → no reactivity overhead
Reactivity jembar ing objek gedhe iku larang; shallowRef/shallowReactive/Object.freeze ngindhari nglacak data sing ora butuh diteteli.
<p>{{ expensiveComputed }}</p> <!-- cached, recomputes only on dependency change -->
<header v-once>{{ siteName }}</header> <!-- render once, never update -->
<div v-memo="[item.id]">...</div> <!-- re-render only if item.id changes -->
Rendering 10,000 rows kills performance → use vue-virtual-scroller / TanStack Virtual
to render only the visible rows.
Vue DevTools (component render timings, why a component re-rendered)
build output / rollup-plugin-visualizer → bundle composition
Lighthouse → Core Web Vitals
Vue cepet sacara default, nanging aplikasi gedhe butuh optimisasi sing sadar: lazy-load kanggo nyidhak bundle, pilih v-if/v-show kanthi bener, gunakake key sing stabil, ngawataake over-reactivity ing data gedhe (shallowRef/freeze), cache karo computed/v-memo, lan virtualisasi daftar sing dawa.
Weruhi teknik mana sing ngatasi bottleneck mana — lan pangukuran karo DevTools/Lighthouse tinimbang menebak — iku sing njaga aplikasi Vue sing berkembang tetap responsif.
