Vue.js Performance Optimization Techniques

Vue.js is fast by default, but large apps can slow down. Here are optimization techniques I use.

Lazy Loading Routes

const routes = [
  { path: '/dashboard', component: () => import('./Dashboard.vue') },
  { path: '/settings', component: () => import('./Settings.vue') }
];

v-once for Static Content

<!-- Renders once, never updates -->
<div v-once>{{ staticContent }}</div>

Virtual Scrolling

For long lists, use vue-virtual-scroller to render only visible items.

Key Tips

• Use computed properties (cached)
• Avoid watchers when computed works
• Use v-show vs v-if appropriately
• Keep components small
