React for interfaces that change under the user’s hands.

React describes an interface as components that re-render when their data changes, which is what makes a dashboard, a configurator or an operations console feel immediate. We use it for the front end of most of the web applications we build, usually with a Node.js or .NET API behind it.

What we build with React.

ReactJS Web App Development.

Our experts are proficient in building robust and scalable web application s using React JavaScript. We leverage the latest ReactJS features to create interactive, responsive, and user-friendly applications that engage your audience.

User Interface Development.

A seamless user experience is vital for the success of any application. Our designers work closely with our developers to ensure your React JavaScript application not only functions flawlessly but also looks stunning and intuitive.

Single Page Applications (SPA).

SPAs provide a more fluid user experience by eliminating the need to refresh the entire page if content on one area of the page changes. React JavaScript supports SPAs that are fast, scale, and create great user experiences.

In practice

Facebook, Instagram and WhatsApp Web are built with React.

What is ReactJS?

React JavaScript, also referred to as React.js or ReactJS, is an open-source library for front-end user interfaces. Facebook (now Meta) originally developed ReactJS to build web and mobile applications. Meta, along with a large community of contributing developers, continues to maintain React. The React library is built on components where each component is a piece of functionality such as a button.

Why use ReactJS versus plain old JavaScript? Imagine you have a web page in an application that has two buttons in different colors. Using JavaScript, you’d need to build and maintain the code for each button independently. This creates a lot of extra work and problems with code manageability. With React, you build a component, then style each use of that component using ReactJS “props” (short for properties).

This makes it both faster to build apps and easier to maintain and change them in the future.

When is React the right choice?

ReactJS is particularly strong for single-page applications or applications that include pages with different panels or sections in which data needs to be loaded and rendered, but reloading the entire page deteriorates the user experience. This is because ReactJS can reload data on a page without having to reload the entire page. Imagine a web application that includes a set of tiles at the top with summary data and a data table below with detailed row-by-row information, and that the data in the tiles needs to be updated automatically when it changes on the backend. React can handle updates to each tile or to the data table without having to refresh the entire page.

What is built with React?

React is one of the most popular JavaScript libraries in the development community. Many of the most successful software applications use React. Examples include:

Facebook. The social networking site uses React JavaScript extensively for its web app, showcasing its capabilities in handling dynamic content and vast amounts of user data.

Instagram. React JavaScript helps power many parts of Instagram’s web application, providing a smooth, dynamic user experience with interactive features and real-time updates.

WhatsApp Web. The web version of the popular messaging app uses React JavaScript to offer seamless synchronization with the mobile app, supporting real-time messaging, notifications, and more.

Airbnb. Known for its innovative approach to UI/UX, Airbnb uses React JavaScript to create a responsive, intuitive platform for booking accommodations and experiences.

Netflix. The streaming giant employs React JavaScript for its platform’s low-latency, highly interactive user interfaces, enhancing the browsing and watching experience.

New York Times. For their website, React JavaScript is used to manage interactive storytelling and multimedia content, offering readers a rich, engaging experience.

Dropbox. The file hosting service uses React JavaScript in parts of its web interface, improving user interaction and efficiency in file management tasks.

Uber. Uber’s web interface for riders and drivers leverages React JavaScript to handle real-time data and provide a smooth, map-intensive user experience.

Twitter. The Twitter Lite web app uses React JavaScript, among other modern web technologies, to provide a fast, efficient, and more accessible version of Twitter.

Asana. The project management tool uses React JavaScript to offer a dynamic, responsive interface for managing tasks, projects, and teams effectively.

Where we're not the right answer

We'll tell you if we're a fit. If we're not, we'll tell you that too.

  • Your current stack works and nobody wants to change it
  • You want licences resold at a discount and nothing else
  • Your internal team owns the operating model and is not handing it over
  • You want hours of configuration work and nothing run for you: that is on our services pages, and it is not a managed solution
How we start

Most of our best clients come to us with a feeling, not a plan.

"Something isn't working." "We're outgrowing our tools." "We're afraid to make the wrong move." No-Risk Discovery is a short, practical conversation that gets you clarity before you commit to anything big. We'll tell you if we're a fit. If we're not, we'll tell you that too.
