React interfaces & web apps on Cyprus

What is React, and how is it different from Next.js?

React is a JavaScript library for building interfaces, created by Meta in 2013. It handles the view layer: components, state, and updates in the browser. Next.js is a full framework built on top of React that adds server-side rendering, file-based routing, and backend features. If your product lives behind a login — an admin panel, a client dashboard, an internal tool — you don't need server rendering. You need a fast, maintainable React app. That's what we build at 62px for companies across Cyprus.

When React is the Right Choice

• Client portals and admin panels — authenticated areas where SEO doesn't matter, but UI speed and state clarity do
• Dashboards and analytics — charts, tables, filters, and real-time data without page reloads
• Configurators and calculators — multi-step flows with complex client-side logic and instant feedback
• Embeddable widgets — a self-contained React bundle that mounts into a third-party website
• Design systems and component libraries — reusable UI kits documented with Storybook and tested in isolation
• Frontend over an existing API — we connect React to your REST or GraphQL backend without touching the server

When React alone is not the best option

• Public websites that need search traffic — a bare React app renders in the browser, so Google sees an empty page. For marketing sites, blogs, and SEO-critical pages, use Next.js instead. We've covered that on our Next.js development page.
• Content-heavy sites with frequent edits — if a marketing team needs to publish daily without developers, a CMS is more practical
• Simple landing pages — for a one-page site with a €1000 budget, static HTML or a website builder is faster and cheaper
• Teams without JavaScript developers — React requires ongoing frontend expertise; if nobody in-house can read the code, maintenance becomes a risk

How much does React development cost in Cyprus?

• Freelancers: €800-4000. Fast, but quality and long-term support vary widely
• Cyprus studios: €4000-18000. Solid work, though not always specialised in complex React apps
• EU agencies: €12000-80000. Premium rates, often oversized for a focused UI project
• 62px: from €1490. A typical client portal starts at €3900, a design system at €8900. We include TypeScript, tests, and deployment.

Technology Stack

• React 18+ — concurrent features, automatic batching, hooks-first architecture
• TypeScript — strict typing across components, props, and API contracts
• TanStack Query — server state, caching, retries, and background refetching without hand-rolled reducers
• React Hook Form + Zod — performant forms with schema validation
• TanStack Virtual — smooth rendering for tables and lists with thousands of rows
• Tailwind CSS — consistent styling without CSS bloat
• Radix UI / shadcn/ui — accessible primitives for dialogs, dropdowns, and toasts
• Vitest + React Testing Library — component tests that catch regressions before users do
• Storybook — isolated component development and documentation
• Vite — instant dev server and fast production builds

State management without the boilerplate

We avoid building custom Redux setups by default. Most state in a React app is server data, and TanStack Query handles it better: caching, deduplication, retries, and loading states out of the box. For local UI state, React's built-in hooks are usually enough. When global state is truly needed, we reach for Zustand — small, fast, and easy to reason about.

• Server data — TanStack Query, not hand-written reducers and effects
• Local UI state — useState and useReducer, scoped to the component
• Global app state — Zustand for theme, auth session, or user preferences
• Forms — React Hook Form with Zod validation, no uncontrolled spaghetti

Performance in React apps

• Virtualization — render only visible rows in long tables and lists; a 10,000-row dataset stays at 60fps
• Code splitting — lazy-load routes and heavy components so the initial bundle stays small
• Memoization — React.memo and useMemo where they actually help, not as cargo cult
• Bundle analysis — we check what ships to the browser and cut dead weight
• Profiling — React DevTools Profiler to find unnecessary re-renders

Accessibility in React interfaces

An admin panel used daily by your team must be usable by everyone. We build with accessibility in mind from the start:

• Semantic HTML and ARIA attributes where needed
• Full keyboard navigation for dialogs, menus, and data grids
• Focus management that doesn't trap users or lose their place
• Colour contrast and visible focus indicators
• Testing with axe and manual keyboard checks

Testing React components

Every component we ship is covered by tests that matter:

• Unit tests — Vitest for utilities, hooks, and pure logic
• Component tests — React Testing Library for user-facing behaviour
• Integration tests — critical flows like login, form submission, and data loading
• Visual regression — optional Chromatic or Playwright snapshots for design systems

Typical React project timelines

• Client portal or admin panel — 4-8 weeks from kickoff to production, depending on the number of views and integrations
• Dashboard with charts and filters — 3-6 weeks, including API integration and performance tuning
• Configurator or calculator — 2-5 weeks for a polished multi-step flow
• Design system / component library — 3-6 weeks with Storybook documentation and tests
• Embeddable widget — 2-4 weeks, including cross-site compatibility checks

Post-launch support

We provide 30 days of free support after go-live. After that, managed services start at €290/month: new features, dependency updates, performance monitoring, and React version upgrades. If you need a public-facing website with SEO, we'll recommend Next.js from the start — and we build those too.
