React

What is React?

React is an open-source JavaScript library built by Meta for creating user interfaces. It launched in 2013 and became one of the most widely used frontend technologies on the web. When you interact with a modern web app that updates instantly without reloading the page, there's a good chance React is doing the work underneath.

Its core idea is the component: a self-contained, reusable piece of UI that owns its own logic and state. A search bar, a product card, a checkout button, each is a component, and complex interfaces get built by composing them. That structure keeps code easier to maintain, test, and grow as the product does. React also uses a virtual DOM to keep rendering fast. Instead of repainting the whole page when data changes, it works out the smallest set of updates needed and applies only those.

React rarely works alone. It pairs with Next.js for server-side rendering and routing, and with React Native to build mobile apps from the same mental model. That reach across web and mobile is a big part of why it became a default choice for product teams.

React at Dallonses

React sits at the centre of most of our web development. We reach for it when an interface has real state to manage, complex flows, or a long life ahead of it, and we build the component architecture so the next developer can move fast without breaking things. Next.js comes in when rendering, routing, and performance matter together.

Global brands come to us with products that have to feel fast and stay maintainable for years. We work alongside their teams to shape the frontend, set the patterns, and leave behind a codebase they can own. The framework is just a tool. What lasts is the architecture and the decisions made together along the way.

Building an interface that has to stay fast and maintainable as it grows? Let's architect it right.
