Vue.js for E-commerce

Vue.js doesn't replace server-side rendering — it complements it. We use Nuxt for SSR/SSG of critical pages (catalog, product cards) and client-side Vue for interactive elements: filters, cart, checkout, product comparison. This gives you the SEO of server pages and the UX of a single-page app.

With proper architecture — positively. We use code splitting and lazy loading of components. Catalog and product cards are server-rendered for instant First Contentful Paint. Dynamic parts (cart, filters) load after the main content. Average Lighthouse Performance score is 90+.

Yes, this is one of the most common scenarios. A Vue.js frontend works with a headless backend via API: Laravel, Medusa, Saleor. Content managers handle products through a familiar admin panel, while customers get a fast, interactive frontend.

Nuxt 3 renders catalog pages on the server (SSR) — search bots receive fully ready HTML with meta tags, structured data, and breadcrumbs. Dynamic elements (filters, cart) hydrate on the client after loading. Route-level cache via ISR (Incremental Static Regeneration) ensures instant loading for repeat visits.

Target initial bundle is under 150KB gzipped. Achieved through: tree shaking of unused code, dynamic imports for heavy components (product card, checkout), lazy loading images via Intersection Observer. Pinia store is split by modules (cart, catalog, user) with lazy hydration. Result: Lighthouse Performance 90+ even on mobile devices.

Vue.js reactivity + WebSocket via Laravel Echo provide: inventory updates without page reload (another buyer purchased the last item), live cart counter in the header, real-time order status notifications. For flash sales — countdown timer and dynamic stock updates. Pinia store syncs between tabs via BroadcastChannel API.
