React development

Component-based interfaces for applications where the screen changes constantly and the data has to keep up.

UI library

Chosen per project

Maintainable handover

React earns its place when an interface has genuine state — filters that combine, forms that react to each other, data that updates while the user is looking at it. Its component model makes that complexity manageable, and its ecosystem means most problems already have a well-trodden solution.

It is not the right answer for a mostly static marketing site, where it adds a JavaScript payload and an SEO consideration in exchange for benefits that page will never use.

What we build with React

Admin dashboards with heavy filtering and live data

Customer portals with authenticated, personalised views

Multi-step forms and configurators with dependent fields

Internal tools replacing desktop applications

Where it fits — and where it does not

Good fit when

Interfaces with substantial, interdependent state

Products expected to grow over several years

Teams that benefit from a large hiring pool

Applications that share components across many screens

Consider something else when

Content sites where a static build would be faster and simpler

Very small projects where the tooling outweighs the benefit

Pages where search indexing is critical and no server rendering is planned

React application

How a React codebase is layered

The structure we build to. Keeping data access out of components is what stops a React application turning into hundreds of files that each fetch their own data slightly differently.

UI components

Presentational primitives with no data access of their own.

State management

Local state first, shared store only where it is truly shared.

API integration

A caching query layer handling loading, error and refetch.

Application

Routes and screens composed from the layers above.

Testing

Behavioural component and integration tests.

Deployment

Build pipeline, bundle budgets and CDN delivery.

How we work with React

Component architecture

A layered structure — primitives, composites, then screens — so the library stays coherent as it grows.

State management

Local state by default; a shared store only where state genuinely crosses component boundaries.

Data fetching

A caching query layer so loading, error and stale states are handled consistently rather than per component.

Testing

Component tests around behaviour, not implementation detail, so refactoring does not break the suite.

Our typical React setup

Typical React stack choices and what we use for each
ConcernWhat we use
RoutingReact Router, or the framework router when using Next.js
Data layerTanStack Query for server state, caching and revalidation
StylingCSS Modules or a token-driven stylesheet system
FormsSchema-validated forms with accessible error handling
TestingVitest or Jest with React Testing Library
BuildVite for applications, Next.js where rendering strategy matters

Frequently asked questions

A client-rendered React app can be indexed, but server rendering or static generation through Next.js is materially better for content that has to rank. For an authenticated dashboard, SEO is irrelevant and plain React is the simpler choice.

React is a library with choices left to you; Angular is a framework that makes many of those choices for you. React suits teams that want flexibility and a large ecosystem; Angular suits organisations that value a prescribed structure across many developers.

Yes. React can be mounted into a single part of a page, which is a common way to modernise one complex screen without rewriting an entire application.
