Deploying fully static Next.js websites on Vercel

Static site generation has a branding problem. Say "static site" and people picture a blog with twelve posts and a contact form. So how far can you actually push it before you need a backend? Further than most people assume. This is a walkthrough of a production site that has no database, no API layer, no user accounts and no server-side state, and still ships 232 prerendered pages with per-user results, shareable links and dynamic social cards. The site is a Spanish political test with nine ideological axes, seventeen parties, fifty-four questions. It is in Spanish, but nothing here depends on reading it. Treat it as the reference implementation. The architecture in one sentence Three data files are the source of truth, everything else is derived at build time, and everything user-specific happens in the browser. That is the whole trick. The rest is consequences. 1. Derive pages, don't author them The site has 232 URLs. Almost none of them were written by hand. There are three data modules: the axes, the parties, and the questions. From those, generateStaticParams produces every content route: // app/ejes/[id]/page.tsx export function generateStaticParams () { return AXES . map (( a ) => ({ id : a . id })) } The interesting one is the comparison pages. Seventeen parties means 17 × 16 / 2 = 136 unique pairs, and each pair gets its own page, its own metadata and its own canonical URL: export function allPairs () { const out = [] for ( let i = 0 ; i < PARTIES . length ; i ++ ) for ( let j = i + 1 ; j < PARTIES . length ; j ++ ) out . push ({ a : PARTIES [ i ]. id , b : PARTIES [ j ]. id }) return out } export function generateStaticParams () { return allPairs (). map (( p ) => ({ pair : pairSlug ( p . a , p . b ) })) } 136 pages from twelve lines. And because the page body is computed from the same vectors, recalibrating one party silently rewrites the sixteen pages that involve it . No CMS, no migration, no content drift. The numbers on the page cannot disagree with
