React development

React: the standard language of web frontend

React is the standard language of frontend development. Component-based architecture, the hooks ecosystem, broad library support — the foundation of modern web products.

We use React standalone (Vite) or inside Next.js — the choice depends on your team's expertise and product needs.

When do we use React standalone?

Next.js is more efficient in most cases, but plain React (Vite + React Router) still wins in some: enterprise internal tools (no SEO need), embedded apps, projects already on Vite.

We make the call during discovery; once Next.js or Vite + React is chosen, the architecture follows.

Component kit and Storybook

A React project's lifespan correlates directly with the quality of its component kit. All button variants, inputs, modals, cards — all documented in Storybook and runnable in isolation.

This kit serves both the design team (code that mirrors Figma components) and the onboarding process for new developers. Storybook becomes a top-level documentation page.

03.

State management choice

React Query (TanStack Query) for server state; Zustand or Jotai for client state — our most-used combo. We rarely use Redux now; lower bundle size and less boilerplate alternatives exist.

React Hook Form + Zod validation for form state. This trio significantly reduces the code written for forms.

04.

Test-first approach

Vitest + Testing Library for components; Playwright for end-to-end user flows. Coverage target: 85%+ on business logic, 70%+ on UI components.

Tests run on every PR in CI/CD; failed tests block merges. This catches regression bugs before production.

Frequently asked questions

React, Vue, or Svelte?

React is today's healthiest choice for ecosystem size and hireability. Vue and Svelte are good tools but can't yet rival React's community and library support.

Class component or function component?

Always function components + hooks for new projects. Class components are legacy. Existing class projects can migrate gradually.

CSS-in-JS or Tailwind?

Tailwind CSS in most of our projects — performance advantage and fast iteration. CSS-in-JS (vanilla-extract, stitches) when very complex design systems are required.
