React JS

A JavaScript library for building UI components — less code, faster rendering, and used by the biggest names on the web.

A glowing atom symbol, representing React JS

React makes building dynamic web applications easier, requiring less code than plain JavaScript while adding more features and functions to your app. It's used by Netflix, Airbnb, Instagram, the New York Times, BBC, Dropbox, IMDb, PayPal and American Express — a strong signal of how well it scales in production.

With React, we build interactive UIs including on-screen menus, search bars, buttons, and anything else that needs to respond to a user — whether that's a Netflix-style streaming site or a simple payment cart.

React's stable code, faster rendering and SEO-friendly output, backed by a large developer community, are why businesses come to us specifically for React development rather than a generic front-end build.

Is React right for you?

The most widely used choice for interactive interfaces, with trade-offs worth knowing.

React's popularity matters for hiring, libraries and long-term support. It is not the answer to every project, so here is a plain guide.

React is a strong fit when

  • Your product has a rich interface: dashboards, editors, marketplaces or live data.
  • You may want a mobile app later and would like to share skills and logic through React Native.
  • You want the largest possible pool of developers, libraries and community help.
  • You need a design system of reusable components shared across several products.

Think twice if

  • Your site is mostly content and ranking on Google is the main goal. Use server rendering, for example with Next.js, or a CMS rather than plain client-side React.
  • You have a very small project. React's tooling may be more than you need.
  • Your team prefers strict, built-in structure. Angular may suit you better.
  • You need a quick brochure website. WordPress will be faster and cheaper.
Beyond the library

React on its own is a library, not a whole solution.

React does one job extremely well: turning data into an interface and updating it efficiently. Everything else, such as routing, data fetching, forms and state, comes from the choices made around it. Those choices decide whether a project stays tidy after two years, so we settle them early and write them down for the team that will inherit the code.

For public-facing sites we usually build with Next.js, a React framework that renders pages on the server so search engines and slow phones receive complete HTML straight away. For logged-in applications, a lighter client-side setup is often enough and quicker to build.

Existing sites do not need a full rebuild to benefit. We can migrate section by section, putting React on the pages that need rich behaviour first and leaving stable pages as they are until it makes sense to move them.

How we work

How a React project runs with us.

  1. 1
    Step 1

    Plan the product

    We define the screens, user journeys and data, and decide where React or Next.js is the right fit.

  2. 2
    Step 2

    Set the foundations

    Project structure, coding conventions and a shared component library, agreed before building.

  3. 3
    Step 3

    Build in iterations

    Working releases every few days that you can try, so feedback shapes the product early.

  4. 4
    Step 4

    Test and optimise

    Automated tests for key logic, plus performance work so pages stay quick on mid-range phones.

  5. 5
    Step 5

    Launch and grow

    Deployment, monitoring and a steady release rhythm for new features after launch.

Common questions

Common React questions, answered plainly.

Plain client-side React sends search engines mostly empty HTML first, which can slow indexing. Using a framework such as Next.js to render pages on the server solves this, and we recommend it for any public page that needs to rank.

React is the library for building interface components. Next.js is a framework built on React that adds routing, server rendering and performance features. Most public websites benefit from Next.js, while many internal tools do not need it.

Yes, usually in stages so the site stays live throughout. We begin with the pages that gain most from interactivity and keep stable pages as they are until it makes sense to move them.

React Native lets us reuse skills and some code across web and mobile, which can lower cost when you need both. Native apps can still be the better choice for some products, and we will say so.

Yes. Large companies run React in production at scale. What makes an enterprise project succeed is structure: agreed conventions, a shared component library, tests and clear ownership of data flows.

Cost depends on the number of screens, integrations and how custom the design is. After a short discussion we give a written quote with a phased scope, so you can start small and extend later.
