React & Next.js Development

React is a library, not a framework, so most of the decisions that decide whether an application is fast are still yours: rendering, routing, data fetching, caching. Next.js makes those decisions explicit and gives you a server on which to make them. We build on both, and we choose the rendering mode route by route — static where content is stable, server-rendered where it is personal, client-side only where it genuinely has to be.

Who this is for

Teams building a product front end that has to be quick on first load and cheap to change afterwards. Companies whose React single-page application has outgrown client-side rendering, with a slow first paint and content search engines never see. Businesses that want a marketing site and an authenticated application to share one codebase and one design system instead of drifting apart.

Problems we solve

• A blank page until the bundle arrives. Client-only React ships an empty shell first; slow connections and crawlers both get nothing to work with.
• Content search engines cannot see. Markup assembled after load, so every route serves the same generic metadata.
• Bundle creep. Every dependency shipped to every visitor because nothing is split by route.
• Waterfall data fetching. Each component fetching on mount, so the page fills in piece by piece.
• Stale pages behind a CDN. No way to refresh one page after a content edit without rebuilding the site.

What we build

• Next.js App Router applications using React Server Components, so data fetching stays on the server and the client bundle carries only what is interactive
• Per-route rendering — static generation, incremental regeneration or server rendering — chosen by what the route actually serves
• On-demand revalidation, so publishing a change refreshes the affected pages instead of triggering a full rebuild
• Typed data layers in TypeScript against REST or GraphQL backends
• Design systems on Tailwind with accessible component primitives, shared between public pages and signed-in areas
• Admin panels and dashboards in the same codebase as the public site
• Unit and end-to-end coverage with Vitest and Playwright on rendering behaviour and the routes that carry revenue

How we work

Rendering strategy is settled first, because everything else inherits it. A route that serves the same HTML to everyone is generated at build time; a route that depends on who is asking is rendered per request; a route whose content changes on a schedule is regenerated incrementally. Server components are the default and interactivity is opted into, which keeps the client bundle small without anyone policing it.

We work in TypeScript end to end, because the contract between the API and the front end is where this class of application usually breaks. Accessibility is built in as components are written rather than audited at the end.

Technologies we use

React with Next.js and the App Router, TypeScript throughout, Tailwind CSS with headless accessible primitives, server components and server actions, Vitest and React Testing Library for units, Playwright for end-to-end runs. Backends are usually Laravel or Node.js; deployment is Vercel or a self-hosted Node server behind nginx, depending on where the rest of the stack lives.

Business benefits

• Content present in the first response, so it is indexable and readable before JavaScript runs
• One codebase and one design system for the public site and the application behind the login
• Content updates that go live without a deployment
• A typed boundary between front end and API, which removes a whole category of runtime bug

Common questions

React or Next.js?

Next.js is React with the server-side decisions already made — routing, rendering, caching and bundling. Plain React is the right answer inside an existing shell that already handles those. For a new application that has to be indexable, Next.js saves you building that layer yourself.

Can you work with our existing React application?

Yes. A client-side React app can usually move to Next.js incrementally, route by route, rather than in one rewrite. We start with the routes where first-load performance or search visibility actually matters.

Which rendering mode will our pages use?

It is decided per route, not per project. Marketing and documentation pages are generated and regenerated on a schedule; dashboards and anything personalised are rendered per request; a handful of genuinely interactive views stay on the client.

Do you build the backend as well?

Usually, yes — most often Laravel exposing a JSON API, with the Next.js application consuming it. We also work against an API your team already owns.

Have a React application that is slow to first paint or invisible in search? Those are usually the same problem, and it is fixable without starting again.
