Uboreshaji wa utendaji wa Vue unashughulikia ukubwa wa bundili, ufanisi wa ukaaji, na gharama ya athari. Hapa kuna mbinu za athari kubwa zaidi.
1. Kugawanya nambari / kupakia kwa butwaa
js
routes = [{ : , : () }];
= ( ());
Uboreshaji wa utendaji wa Vue unashughulikia ukubwa wa bundili, ufanisi wa ukaaji, na gharama ya athari. Hapa kuna mbinu za athari kubwa zaidi.
routes = [{ : , : () }];
= ( ());
Faida kubwa zaidi ya upakiaji wa awali: usitume nambari ambayo mtumiaji hajahitaji bado.
<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
Athari ya kina kwa vitu vikubwa sana ni ghali; shallowRef/shallowReactive/Object.freeze hutaka kufuata data ambayo haihitaji.
<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 ni haraka kwa chaguo-msingi, lakini programu kubwa zinakuhitaji uboreshaji wa makusudu: upakiaji wa butwaa kupunguza bundili, chagua v-if/v-show kwa usahihi, tumia funguo thabiti, epuka athari zidogo kwenye data kubwa (shallowRef/freeze), akiba na computed/v-memo, na weka orodha ndefu maalum.
Kujua ni mbinu gani inayosuluhisha shida gani — na kupima na DevTools/Lighthouse badala ya kubahatisha — ndilo litakalo kuweka programu ya Vue inayokua ikiwa na heshima.
