MVP ForSale Promo Storefront
MVP ForSale (mvp.forsale) is a server-rendered promotional listing storefront for an MVP Hub-style marketplace, built on Next.js 16 (App Router) and React 19 with plain JavaScript and zero UI-framework dependencies. It is a read-only catalog frontend: every page fetches the marketplace catalog server-side from MVP Hub's public API, so crawlers and link previews receive full HTML, and every buy action deep-links back to the marketplace with UTM attribution. SEO is the core feature set — per-listing metadata and Open Graph tags, schema.org Product JSON-LD with offer price and aggregate rating, canonical URLs, a live sitemap.xml generated from the catalog, robots.txt, and noindexed search results. The catalog UX covers category landing pages with data-derived subcategory chips, faceted search (category, tech stack, capability, price slider), client-side sort, listing detail pages with gallery, seller-provided markdown body (rendered with raw HTML stripped), readiness badges, verified-review counts, and multi-variant "from" price ranges. Data-integrity guards are built in: reviews are never fabricated, unpriced listings never show $0, demo buttons only render for real demo links, and sold-out or coming-soon sale statuses are respected. The visual theme is a distinctive hand-drawn wireframe aesthetic (Kalam handwriting font, sketch-style browser chrome) that is deliberately easy to re-skin: one CSS file, design tokens at the top. Easy to set up — clone, set three env vars (API origin, public marketplace origin, canonical site origin), pnpm install, pnpm dev; ships with a BuildKit-secret Dockerfile producing a Next.js standalone image with a liveness health route for blue/green deploys. Pluggable against any backend exposing the /api/mvps list + detail contract. Ideal for marketplace operators who want a second themed storefront or SEO promo surface for the same catalog, agencies white-labelling listing sites, and developers who want a clean reference for server-rendered catalog SEO on the App Router.
