The default starting point for a new web app is now a server-first meta-framework (Next.js for React, Nuxt for Vue, SvelteKit for Svelte) rather than a plain client-side single-page app. These frameworks render HTML on the server, send only the JavaScript a page needs, and handle routing, data loading and caching for you. The result is faster first loads and pages that search engines can actually read.
Why server-first won
I learned this the hard way on my own portfolio. As a client-side React app, it sent Google an empty <div id="root"> and 13 of its 14 sitemap URLs returned 404. Moving to Next.js fixed both. I wrote up the whole story.
The general reasons:
- SEO: content is in the HTML from the first byte, for Google, link previews and AI crawlers alike.
- Speed on real phones: less JavaScript to download and run before something useful appears.
- Simpler data loading: fetch on the server, close to the database, without client-side waterfalls.
- Security: secrets and business logic stay on the server.
How the main options compare
| Framework | UI library | Best for |
|---|---|---|
| Next.js | React | Most React teams; strong Vercel integration |
| Nuxt | Vue | Vue teams; flexible rendering per route |
| SvelteKit | Svelte | Small bundles, simple mental model |
| React Router (framework mode) | React | Teams coming from Remix |
When a plain SPA is still fine
Logged-in dashboards and internal tools that don't need SEO can work perfectly well as client-side apps. Even there, a server-first framework rarely makes things worse.
