Laravel + Vue.js + Vite: The Ultimate Performance Optimization Guide

Imagine this: Your Laravel+Vue application takes 8 seconds to load. Users are bouncing. Google ranks you poorly. Your competitors' apps feel instantaneous. What went wrong?

After optimizing dozens of Laravel-Vue applications, I've discovered the 7 most impactful performance boosters that most developers miss. Implement these today and watch your app speed skyrocket!

🔥 1. The Vite Build Game-Changer

Problem: Default Vite builds include unnecessary code
Solution: Smart code splitting + compression

// vite.config.js
export default defineConfig({
  build: {
    rollupOptions: {
      output: {
        manualChunks: (id) => {
          if (id.includes('node_modules')) {
            if (id.includes('lodash')) {
              return 'vendor-lodash';
            }
            return 'vendor';
          }
          if (id.includes('stores')) {
            return 'stores';
          }
        }
      }
    },
    minify: 'terser',
    terserOptions: {
      compress: {
        drop_console: true,
        drop_debugger: true
      }
    }
  }
});

Pro Tip: Add this to your deployment script:

vite build --mode production --emptyOutDir

⚡ 2. The Lazy Loading Revolution

Before: 500KB initial load
After: 80KB initial load

// router.js
const routes = [
  {
    path: '/dashboard',
    component: () => import('@/views/Dashboard.vue'), // Lazy-loaded
    meta: { preload: true } // Hint for prefetching
  }
];

// In your main layout
onMounted(() => {
  router.getRoutes().forEach(route => {
    if (route.meta.preload) {
      router.preloadRoute(route.path);
    }
  });
});

🏎️ 3. API Response Compression (Laravel Side)

Install:

composer require spatie/laravel-responsecache
php artisan vendor:publish --provider="Spatie\ResponseCache\ResponseCacheServiceProvider"

Usage:

// app/Http/Controllers/UserController.php
public function index()
{
    return responsecache()
        ->remember(now()->addHours(12), function () {
            return User::with('profile')->get();
        });
}

🖼️ 4. Image Optimization That Actually Works

Vite Plugin Setup:

npm install vite-plugin-image-optimizer --save-dev

Configuration:

// vite.config.js
import { imageOptimizer } from 'vite-plugin-image-optimizer';

export default defineConfig({
  plugins: [
    imageOptimizer({
      jpg: { quality: 80 },
      png: { quality: 80 },
      webp: { lossless: false },
      avif: { lossless: false },
      cache: true,
      cacheLocation: './node_modules/.cache/image-optimizer'
    }),
  ]
});

🧠 5. Smart State Management

Pinia Optimization Strategy:

// stores/auth.js
export const useAuthStore = defineStore('auth', {
  state: () => ({
    _user: null,
    _lastHydrated: 0
  }),
  getters: {
    user: (state) => {
      // Only rehydrate if data is older than 5 minutes
      if (Date.now() - state._lastHydrated > 300000) {
        this.hydrate();
      }
      return state._user;
    }
  },
  actions: {
    async hydrate() {
      this._user = await fetchUser();
      this._lastHydrated = Date.now();
    }
  }
});

🌐 6. The CDN Setup Everyone Misses

Laravel Filesystem Config:

// config/filesystems.php
'disks' => [
    'cdn' => [
        'driver' => 's3',
        'url' => env('CDN_URL'),
        'visibility' => 'public',
        'bucket' => env('CDN_BUCKET'),
    ],
],

Vite Asset Handling:

// vite.config.js
export default defineConfig({
  base: process.env.NODE_ENV === 'production'
    ? 'https://yourcdn.example.com/assets/'
    : '/',
});

🛑 7. Critical CSS Extraction

Install:

npm install vite-plugin-critical --save-dev

Configuration:

// vite.config.js
import critical from 'vite-plugin-critical';

export default defineConfig({
  plugins: [
    critical({
      criticalUrl: 'http://localhost:3000',
      criticalBase: './dist',
      criticalPages: [
        { uri: '/', template: 'index' },
      ],
      criticalConfig: {
        width: 1300,
        height: 900,
      },
    }),
  ],
});

🚀 Bonus: The Ultimate Deployment Checklist

1. Enable OPcache in PHP

   [opcache]
   opcache.enable=1
   opcache.memory_consumption=256
   opcache.max_accelerated_files=20000
   

2. Database Indexing

   // Add to your migrations
   $table->index(['email', 'created_at']);
   

3. Queue Workers

   sudo supervisorctl restart laravel-worker:*
   

4. Lighthouse Score Booster

   // Add to your main layout
   <link rel="preconnect" href="https://api.yourdomain.com">
   <link rel="preload" as="script" href="/assets/vendor.js">
   

📈 Real-World Results
