What Is React?
React is an open-source JavaScript library for building user interfaces. It was created at Facebook, now Meta, and released as open source in 2013. In React an interface is a tree of components: a button, a card, a form or a whole page, each one a self-contained piece of code that can be reused wherever it's needed.
React works declaratively: instead of telling the browser step by step what to change, we describe what the interface should look like in a given state, such as “cart empty” or “three items”, and React updates only the parts of the page that changed. Components are usually written in JSX, which looks like HTML inside JavaScript, and receive data through props, while hooks such as useState and useEffect handle state and tasks like loading data.
React is free under the MIT license. In February 2026 Meta handed it over to the React Foundation, an independent foundation hosted by the Linux Foundation, whose members include Meta, Microsoft and Amazon; its technical direction is still set by the people who build and maintain it. React focuses on the interface itself, so for routing, server rendering and SEO it is often paired with a framework such as Next.js.
Where We Use React
We reach for React when a page needs to behave like an application rather than a document. It suits these jobs best:
Dashboards and Client Portals
Panels where your team or your customers sign in, see their data, filter tables and update records. React keeps complex screens fast and organized as they grow.
Interactive Sections
A price calculator, a product configurator or a booking form inside an otherwise simple page. We add a React component only where it's needed and keep the rest of the page light.
Components from Your Figma Library
We turn the components in your Figma design system, such as buttons, cards and forms, into React components with the same names and variants, so design and code stay in step.
Web Apps with Next.js
For larger sites and apps we pair React with Next.js: public pages are rendered on the server for speed and search engines, and the framework handles routing, including separate addresses for each language.
Why React?
Built from Reusable Pieces
A button or a card is built once and used everywhere. Improving it in one place updates every screen, which keeps large interfaces consistent and makes each change quicker.
Predictable as It Grows
Data flows one way, from parent components to their children, and each component shows exactly what its state says. Complex screens become easier to follow, test and extend.
A Broad, Lasting Ecosystem
React is backed by an independent foundation and a large community, with well-maintained tools for forms, charts, maps and accessibility. Many developers know it, so future maintenance is easier to arrange.
How We Work on Your Project
We start from the design system in Figma: we list the components with their variants and states, then build them in React, usually with TypeScript, from the smallest pieces up to full screens. Each component is checked on its own before it goes onto a page.
Before launch we test the screens with a keyboard and a screen reader, check speed and responsiveness with Lighthouse and PageSpeed Insights, and make sure content meant for search engines arrives as ready-made HTML. At handover your team receives the code and a walkthrough of how to update content.
