React

Production-grade React platforms — regulated portals, citizen services, enterprise dashboards.

Delivery depth

React-based platforms shipped for government, regulated industry, and global enterprise clients — including the site you're reading

OVERVIEW

Why React, where it fits.

React is Intellectual's default for new enterprise frontend work — citizen-facing government portals, regulated industry dashboards, internal administrative tools, and the application layer of integration-heavy platforms. We deliver in both Next.js (App Router, server components, static export) and standalone Vite-based React when the deployment target demands it.

Our React work is opinionated about architecture. Component composition, design-system discipline, accessibility (WCAG 2.1 AA targets), performance budgets (Core Web Vitals), and a server-state strategy that doesn't fall apart under realistic enterprise data volumes.

Most of what makes a React codebase survive its third year is decided in the first six months: state architecture (Tanstack Query / Zustand / Redux Toolkit), boundary discipline between server and client components, accessibility-first design tokens, and a build pipeline that catches regressions before they ship. We bring that up front.

HOW WE USE IT

Delivery patterns we apply.

The engagement patterns Intellectual repeatedly delivers on React, drawn from real programmes.

Fig TS.REA.AReact — Delivery Patterns
[REA.1]

Next.js application architecture

App Router design, server / client component boundaries, server actions or external API integration, route-group layout strategy, metadata and SEO foundation (this site is built that way).
[REA.2]

Design systems and component libraries

Composable design systems with tokens (colour, spacing, typography), Radix or HeadlessUI primitives, Tailwind or CSS-in-JS strategy, and accessibility built into every base component.
[REA.3]

State and data management

Tanstack Query for server state, Zustand or Redux Toolkit for client state, optimistic updates, suspense / streaming UI, and offline-capable patterns for field operations.
[REA.4]

Performance and accessibility

Core Web Vitals budget enforcement (LCP, CLS, INP), code-splitting strategy, image and font optimisation, WCAG 2.1 AA targets, keyboard / screen-reader testing, and prefers-reduced-motion compliance.
[REA.5]

Mobile and offline

React Native and Expo for cross-platform mobile, PWA strategy for offline-capable government and field-operations applications, and the back-end synchronisation patterns that go with each.
