SPA frameworks like Next.js, Nuxt, and SvelteKit dominate frontend development, but they carry significant JavaScript overhead that hurts performance-critical use cases like eCommerce.

Marko demonstrated 60–84% savings in JS bundle size on eBay pages using this approach. React 18's Server Components and Streaming SSR help but don't fully close the gap. For sites where initial load performance directly impacts revenue, MPA-oriented frameworks offer optimizations that SPA architectures structurally cannot match.
