// Overview
How we use React
React underpins virtually all of our frontend work, component-based architecture, a rich ecosystem, and broad team familiarity make it the right choice for most projects. We use modern React patterns including hooks, context, and concurrent features.
// Use cases
- Web application UIs
- Design system implementations
- Interactive dashboards
- Complex form and workflow UIs
- Real-time data visualisations
// Why it matters
Composable architecture
React component model enables reusable, testable UI building blocks that compose into complex interfaces without becoming unmaintainable.
Rich ecosystem
Tailwind, Radix UI, React Query, Zustand, and a mature testing ecosystem mean rarely needing to build primitives from scratch.
Team familiarity
The largest frontend ecosystem means readily available engineers and extensive community resources for every problem pattern.
// Production patterns
How we ship with React
Component boundaries follow atomic design, primitives in a shared UI package, feature modules colocated by domain, and Storybook or Ladle for visual regression on high-traffic components.
State management is intentional: server state via React Query or SWR, client UI state via hooks or Zustand, we avoid global Redux unless undo/redo or complex middleware truly requires it.
Design system handoffs map Figma variables to Tailwind theme extensions so spacing and colour drift is caught in CI, not in QA. We have executed full UI-library migrations on large production codebases, replacing MUI component-by-component with custom Tailwind primitives, with no feature freeze and no half-migrated states.
// FAQ
React: common questions
Do you still use class components?+
No on greenfield work. Legacy class components are migrated incrementally when touching those surfaces for other reasons.
How do you test React UIs?+
Vitest or Jest for unit tests on logic; Playwright for critical flows; optional Chromatic for design system snapshots when ROI is clear.
Can React share code with React Native?+
Yes, business logic, types, and API clients live in a monorepo package consumed by Next.js and Expo apps.
