Next.js & React Applications Built on the Current Stack, Not the 2022 One
Next.js and React application development — Server Components, Vercel Edge deployment, and a build process that avoids the hydration and bundle-bloat mistakes that sink most React rebuilds.
Definition
What We Build: Next.js & React Applications
Next.js (App Router) applications using React Server Components to minimize client-side JavaScript, TypeScript throughout, and deployment on edge infrastructure (Vercel Edge Functions) for low-latency rendering — not a client-rendered single-page app dressed up as "modern."
The distinction that actually matters isn't "React vs. something else" — it's whether the team building it understands which parts of the app should run on the server and which shouldn't. Get that wrong and you end up with a slow app that merely looks modern.
The Technical Decisions That Separate a Fast App from a Slow One in a Next.js Wrapper
We commit to a default position per decision and say why — engineering judgment, not a framework feature list.
| Decision | What we default to, and why |
|---|---|
| Rendering strategy | React Server Components by default, client components only where interactivity genuinely requires them — most "slow Next.js sites" are slow because everything was made a client component out of habit, defeating the entire point of the architecture |
| Data fetching & caching | Partial Prerendering where the route mixes static and dynamic content, so a page isn't forced entirely static or entirely server-rendered just because one section needs live data |
| Deployment target | Vercel Edge Functions for latency-sensitive routes; standard Node.js runtime where a route needs full Node API access — chosen per-route, not defaulted globally |
| Component library | shadcn/ui as the base — copied into the codebase and owned by the client, not a black-box dependency that breaks on an unrelated version bump |
| Type safety | TypeScript end to end, including typed API boundaries to whatever CMS or backend the app pulls from |

The Mistakes That Show Up After Launch, Not During the Demo
Client-component overreach
Marking a component "use client" by default (often because an AI coding assistant or a copy-pasted tutorial defaults to it) silently ships the entire component tree's JavaScript to the browser, erasing the performance benefit Server Components exist to provide.
Hydration mismatches
Server-rendered markup that doesn't exactly match what React renders client-side produces console errors and, worse, layout shift that hurts both UX and Core Web Vitals; this is caught in code review, not discovered by a user reporting a glitchy page.
Over-fetching in Server Components
Because Server Components can query a database or API directly, it's easy to fetch more than a given route actually needs; without discipline here, "simpler data fetching" turns into slower pages.
Cache misconfiguration
Treating every route as either fully static or fully dynamic, instead of using Partial Prerendering deliberately, either stales content that should be live or removes caching benefit that should exist.
Bundle bloat from unnecessary client libraries
Pulling in a heavy client-side charting or animation library for something that could be server-rendered or done in CSS is the single most common cause of a Next.js app that "should be fast" but isn't.

How These Applications Get Validated Before Launch
Every build goes through automated end-to-end testing before deployment. A component-driven app is exactly the kind of codebase where regression testing catches a broken interaction before a user does — this is the same connected-delivery proof point we run across the site, made concrete here.

Frequently Asked Questions
Plain React renders entirely in the browser, which means search engines and AI crawlers see an empty shell unless you add server rendering yourself. Next.js gives you server rendering, static generation, and Partial Prerendering out of the box, plus file-based routing and edge deployment. If your pages need to be found in search or need to load fast on first paint, Next.js handles work that plain React leaves to you.
