A frontend that feels fast. A backend that just works.

Inertia.js Monolith is the best architecture for most full‑stack apps in 2026 because it lets you build fast, interactive SPAs without creating a separate API, reducing complexity and keeping backend/frontend tightly coupled for simpler development and deployment. Go for separate Laravel API + Vue/React SPA only if you need multiple frontends (mobile, admin, public site) or a fully decoupled microservices setup, as it adds overhead in API design, auth, and versioning that slows you down early on.

Keep Laravel backend code in app/Http/Controllers and app/Models as usual, while organizing frontend in resources/js with clear folders like pages/ (Inertia pages), components/ (shared UI), composables/ (logic hooks), stores/ (state), and types/ (shared interfaces). Use Vite aliases (@/ for js root) and domain‑driven folders (e.g., modules/users/, modules/orders/) so as the app grows, features stay self‑contained and easy to navigate without deep nesting.

Enable Inertia SSR by setting it true in config/inertia.php, installing @inertiajs/server and vue/server-renderer, and running a Node SSR server alongside your PHP app; it pre‑renders Vue/React components on the server for crawlers. SSR is necessary mainly for SEO on content‑heavy public pages (blogs, products) where Google needs fast, complete HTML—skip it for authenticated dashboards where interactivity trumps crawlability.

For scale, use composables (Vue) or custom hooks/context (React) for local state, Pinia/Zustand for lightweight global state (user, cart), and avoid heavy stores unless you have complex cross‑feature syncing—the Laravel backend handles most persistence, so frontend state stays simple and debuggable.

Configure Vite for code‑splitting (dynamic imports on routes), tree‑shaking unused code, and minification in production; lazy‑load non‑critical components and images, and use Laravel route caching with Inertia’s shared data props to minimize bundle reloads.
