React is Meta's open-source JavaScript library for building user interfaces. Released in 2013 and now on version 19, it introduced component-based UI development and the virtual DOM to the mainstream. Today it's the most widely used frontend library in the world, powering everything from small landing pages to complex enterprise applications.
What makes React the first choice for complex, interactive user interfaces.
React's core concept: build UIs as a tree of isolated, reusable components. Each component manages its own state and renders predictably given the same props. This model scales from a single button to a 500-component enterprise dashboard.
Introduced in React 16.8, Hooks (useState, useEffect, useContext, useReducer and custom hooks) replaced class components entirely. They make stateful logic composable and shareable across components without wrapper hierarchies.
React 19 (2024) brought stable React Server Components, the new Actions API and first-class form handling. Server Components run only on the server, reducing client-side JavaScript and enabling direct database access in the component tree when used with Next.js.
React 18 introduced the concurrent renderer with useTransition, useDeferredValue and Suspense for data fetching. The result: UIs that stay responsive during heavy rendering work and show loading states without waterfall delays.
React Router v7, TanStack Query, Zustand, Redux Toolkit, Radix UI, shadcn/ui, Storybook — the React ecosystem has a well-maintained solution for every common frontend problem. No other library matches this breadth.
React has first-class TypeScript support. Component props, event handlers, context values and custom hooks all benefit from static type checking. Our standard is TypeScript-only for all new React projects.
When decoupling your storefront from Sylius, Shopware or Shopify, React (typically via Next.js) gives you full design freedom while the platform handles commerce logic through its API.
Internal tools, customer portals and data-heavy dashboards where rich interactivity, real-time updates and a component library matter more than SEO or initial load time.
Teams that want a single language across frontend, backend (Node.js) and mobile (React Native) — reducing context-switching and enabling shared type definitions.
We use React and Next.js for headless storefronts, SPAs, dashboards and custom admin interfaces — always in TypeScript.
React frontends for headless commerce, SPAs, custom dashboards and admin tools. We build with TypeScript, clean component architecture and performance in mind.
Connect a React frontend to your Sylius, Shopware or custom commerce API — product listing, cart, checkout and account flows.
FAQ
React 18 (2022) introduced concurrent rendering — the ability to interrupt, pause and resume rendering work. React 19 (2024) stabilised React Server Components, introduced the Actions API for async transitions, improved form handling with the new useFormStatus and useActionState hooks, and added the use() hook for reading promises and context in render. For new projects, React 19 is the recommended version.
React is a library — specifically for building UI component trees. It intentionally does not include routing, data fetching, server rendering or build tooling. For a full framework experience, pair React with Next.js (for web) or Expo (for mobile). This separation lets you choose the best tool for each concern.
For new projects, we default to React because of its larger ecosystem, deeper TypeScript integration and our team's greater depth with it. Vue.js is a solid alternative — it has a gentler learning curve and excellent developer experience. If your team already knows Vue, there's no compelling reason to switch. We can work with both.
Yes. All new React projects we start use TypeScript. It eliminates entire categories of runtime errors, makes refactoring safer and dramatically improves IDE support. The overhead of adding TypeScript to a React project is low; the long-term benefit is significant.
Yes — this is one of our most common use cases. Sylius exposes a REST and GraphQL API; Shopware provides its Store API. A React/Next.js frontend fetches product, cart and checkout data from those APIs, giving you full control over the UX while the platform manages the commerce backend.
