Production web apps. Built on Next.js.
Zupitrix uses Next.js when the product needs a fast public site, a signed-in application, or a headless storefront from one codebase. We choose server and client boundaries, caching, and hosting before features pile up — so SEO, Core Web Vitals, and deploys stay predictable.
Pages stay on the server unless interaction needs a client component. Forms, carts, and editors are isolated so the rest of the tree stays small. We document the approach, name owners, and attach acceptance checks so “Server and client boundaries” is reviewable in demos and durable after handoff.
Static, revalidated, and dynamic routes are labeled in the architecture. Editors know what publishes instantly and what waits for a rebuild or tag. We document the approach, name owners, and attach acceptance checks so “Caching you can explain” is reviewable in demos and durable after handoff.
Titles, canonicals, Open Graph, and JSON-LD live with the page. Content models expose the fields those tags need. We document the approach, name owners, and attach acceptance checks so “SEO as part of the route” is reviewable in demos and durable after handoff.
Preview environments, environment variables, and a production checklist are part of the repo — not a one-off setup on one laptop. We document the approach, name owners, and attach acceptance checks so “A deploy path the team owns” is reviewable in demos and durable after handoff.
02 — Build
Multi-page sites with a CMS, fast landing routes, and analytics that do not block first paint. We document the approach, name owners, and attach acceptance checks so “Marketing and content sites” is reviewable in demos and durable after handoff.
Authenticated areas, dashboards, and workflows sharing a design system with the public site. We document the approach, name owners, and attach acceptance checks so “Product applications” is reviewable in demos and durable after handoff.
Catalog, cart, and checkout UX on Next.js while Shopify, Magento, or a custom API owns commerce truth. We document the approach, name owners, and attach acceptance checks so “Headless storefronts” is reviewable in demos and durable after handoff.
03 — Flow
List public, cached, and private routes and the data each one needs. Exit criteria and owners are written down before the next step starts.
Mark server components, client islands, and route handlers. Exit criteria and owners are written down before the next step starts.
Lock Core Web Vitals and bundle limits before feature work accelerates. Exit criteria and owners are written down before the next step starts.
Preview deploys, metadata checks, and a production runbook. Exit criteria and owners are written down before the next step starts.
Validate budgets, failure modes, observability, and rollback before traffic. Exit criteria and owners are written down before the next step starts.
Runbooks, access, and training so the client team can operate without us. Exit criteria and owners are written down before the next step starts.

Outcomes
Product and engineering goals we keep visible from the first slice through handoff — so velocity never quietly trades away quality.
At a glance
Typical timelines, coverage, and operating constraints we set expectations against before the build surface expands.
| Topic | Value | Note |
|---|---|---|
| Typical first ship | 4–8 weeks | Marketing + core product slice. Tracked against Next.js delivery milestones. |
| Preview latency | <10 min | From merge-ready PR. Tracked against Next.js delivery milestones. |
| Route modes | 3+ | Static / ISR / dynamic documented. Tracked against Next.js delivery milestones. |
| Client islands | Minimal | Measured, not assumed. Tracked against Next.js delivery milestones. |
| CMS models | Typed | Fields match SEO + UI. Tracked against Next.js delivery milestones. |
| Hosting | Flexible | Vercel or Node/Docker/AWS. Tracked against Next.js delivery milestones. |
Ecosystem
Real stack partners we wire into delivery with clear roles — not decorative logos on a slide.
Component model and concurrent rendering for the app shell.
Shared types across UI, APIs, and data access.
Branch previews, edge middleware, and production deploys.
Utility-first styling tied to product tokens.
Structured content models editors can own.
Checkout, billing, and webhook-safe money flows.
Typed queries and migrations against the system of record.
Hot-path cache, rate limits, and session stores.
Server runtime for APIs, jobs, and SSR hosts.
Transactional source of truth with backup and access control.
Repeatable images for preview, staging, and production.
Production errors with release and user context.
Integrations
CMS, identity, commerce, analytics, and edge services joined with typed contracts, webhooks, and ownership — not ad-hoc glue.
Editor workflows with preview and publish hooks.
Catalog, cart, and checkout backed by commerce platform.
Login, SSO, and session policies for private routes.
Product and marketing events without blocking paint.
Typed indexes for docs, catalog, or help content.
Edge cache, bot protection, and TLS termination.
Architecture
Boundaries, ops knobs, and rollback policy for each layer — so one team can change without rewriting everything.
Auth cookies, geo, and feature flags before the page tree runs.
Layouts and pages fetch data; client islands stay small.
BFF endpoints for forms, webhooks, and signed downloads.
Tags and time-based revalidate matched to content ownership.
Web Vitals, errors, and product analytics without blocking paint.
Capabilities
Concrete workstreams with owners, acceptance checks, and a path for your engineers to extend after handoff.
Next.js · App Router · RSCLayouts, parallel routes, and server-first trees that stay cacheable.
Static, revalidate, and dynamic routes labeled before features pile up.
LCP, CLS, and bundle limits enforced in review — not after launch.
Route handlers and middleware for auth, geolocation, and A/B flags.
Titles, canonicals, Open Graph, and JSON-LD owned with the page.
Headers, CSRF-aware forms, and secret handling kept off the client.
next/image, self-hosted fonts, and third-party script budgets as part of the build.
Branch previews, env separation, and a production checklist the team owns.
Server fetches, tagged revalidation, and BFF handlers that keep secrets server-side.
Patterns
Reference implementations and conventions in the repo — so reviews reject one-off variants that bypass the agreed shape.
Default to RSC; opt into client only for interaction.
Reference implementation of “Server-first pages” lives in the repo, not only slides.Static shell + dynamic holes where product needs freshness.
Reference implementation of “Partial prerendering mindset” lives in the repo, not only slides.Editors publish; tagged routes refresh without full rebuilds.
Reference implementation of “Tagged cache invalidation” lives in the repo, not only slides.Independent fetches in the tree instead of waterfalls.
Reference implementation of “Parallel data loading” lives in the repo, not only slides.SEO fields live with the route that owns the content.
Reference implementation of “Metadata colocated” lives in the repo, not only slides.Shared UI package used by marketing and app routes.
Reference implementation of “Design-system islands” lives in the repo, not only slides.Industries
Same technical playbook, different module depth — regulation, uptime, and partner APIs baked in early.
Marketing site + authenticated product in one Next.js codebase.
