Overview

What React developers do, and where React projects go wrong

React is the most widely used library for building user interfaces on the web. It lets developers split a screen into small, reusable components, each with its own state and logic. That makes it a strong fit for interactive software: admin panels, analytics dashboards, booking tools, editors, internal tools and customer portals. React developers turn designs into these components, connect them to APIs, manage the data that flows between them and make sure the result works on every screen size.

React itself is small, which is both its strength and its risk. It does not decide how you route pages, fetch data, manage global state, style components or test them. Every team makes those choices, and early choices are hard to undo. A project that picked Redux for everything, fetched data inside useEffect calls and skipped tests can feel fine at ten screens and painful at fifty. Senior React developers know which tools fit which problems and how to keep the codebase consistent as it grows.

The most common problems we see in React apps are slow screens caused by needless re-renders, huge JavaScript bundles, data that goes stale or loads twice, forms that are hard to validate, and components nobody dares to touch because there are no tests. None of these are React's fault. They come from missing structure. Our developers fix them with clear patterns: server state in TanStack Query, local state kept close to where it is used, and components tested the way users actually use them.

When you hire React developers from Dware, you get engineers who write modern React with TypeScript, function components and hooks, and who keep up with changes such as React 19, Actions and the React Compiler. They can start a new single-page app with Vite, join an existing codebase, or work inside a Next.js project. They care about accessibility and performance as much as appearance, because a dashboard that looks good but lags on every click still loses users.

What we build

React development services our engineers deliver

Our React developers work on front ends of every size, from a single new screen to a full product. These are the projects we are asked for most.

  • Single-page applications built with Vite

    Fast client-side apps using Vite, TypeScript and React Router or TanStack Router. Ideal for logged-in products where SEO does not matter and you want a simple static deploy to any CDN.

  • Dashboards and data-heavy interfaces

    Tables with sorting, filtering and pagination over thousands of rows, built with TanStack Table and virtualised lists. Charts with Recharts, Visx or ECharts that stay smooth while data updates in real time.

  • Design systems and component libraries

    Shared buttons, inputs, modals and layouts built on accessible primitives like Radix UI or React Aria, documented in Storybook and published as a versioned package. One source of truth for every product team.

  • Complex forms and multi-step flows

    Onboarding wizards, checkout, insurance or loan applications built with React Hook Form and Zod. Validation is shared with the back end, errors are clear, and progress is never lost on refresh.

  • Real-time and collaborative features

    Live notifications, chat, presence and collaborative editing over WebSockets, Server-Sent Events or tools like Liveblocks and Yjs. We handle reconnects and conflicting updates so the UI never shows stale data.

  • React performance audits and fixes

    We profile your app with React DevTools and Chrome performance tools, find the slow renders and heavy bundles, and fix them. You get a written report with measured before and after numbers.

  • Migrations to modern React

    Moving class components to hooks, Create React App projects to Vite, JavaScript to TypeScript, or legacy jQuery and AngularJS screens to React one route at a time. Users never see a big-bang rewrite.

  • Accessibility remediation

    Audits against WCAG 2.2 AA with axe and manual screen reader testing in VoiceOver and NVDA, then fixes for focus handling, keyboard navigation, labels and colour contrast across your components.

Our process

How our React developers build your app, step by step

Whether we start from a blank Vite project or join a large existing codebase, React work follows the same steps. Each one has React-specific decisions that are cheap to get right early and expensive to fix later.

  1. 1

    Discovery: users, screens and data

    We start with a free consultation to understand who uses the app, which screens matter most and where the data comes from. We review your designs in Figma, your API documentation and, if there is one, your current React codebase. We list the screens, the shared components and the data each screen needs. This tells us early whether you need a plain single-page app, a Next.js app or a component library.

    What you get

    • Screen and component inventory
    • API and data map
    • Free, fixed quote
  2. 2

    Architecture and tooling choices

    We choose the foundations and write them down. Typical choices are Vite or Next.js, TypeScript in strict mode, React Router or TanStack Router, TanStack Query for server state, Zustand or plain React context for the little global state that is left, and Tailwind CSS or CSS Modules for styling. We agree on a folder structure by feature, not by file type, so related code lives together. Each decision gets a short note explaining why, so future developers understand it.

    What you get

    • Architecture decision notes
    • Project skeleton in your repo
    • Linting and formatting rules
  3. 3

    Design system and component foundations

    Before building screens, we build the pieces they share: typography, colour tokens, buttons, inputs, selects, dialogs, tables and layout. We base them on accessible primitives such as Radix UI or React Aria, so keyboard and screen reader support come built in. Each component gets Storybook stories that show every state, including loading, empty, error and disabled. Designers and product managers can review these in the browser before a single screen exists.

    What you get

    • Core component set
    • Storybook with every state
    • Design tokens synced with Figma
  4. 4

    Building features in small slices

    We build one user-facing feature at a time, end to end: the screen, its data fetching, loading and error states, and its tests. Data comes through typed API clients, often generated from your OpenAPI or GraphQL schema, so a back-end change shows up as a TypeScript error instead of a bug in production. Every slice goes out as a small pull request with a preview link, reviewed by a second senior Dware engineer.

    What you get

    • Working features behind preview links
    • Typed API client
    • Reviewed pull requests
  5. 5

    Testing with React Testing Library and Playwright

    We test components the way users use them. React Testing Library with Vitest checks that clicking, typing and submitting do the right thing, without depending on internal details that change during refactoring. Mock Service Worker fakes the API so tests run fast and offline. Playwright then runs the critical journeys, such as sign-up, search and checkout, in real Chromium, Firefox and WebKit browsers on every pull request, with axe checks for accessibility built in.

    What you get

    • Component tests in Vitest
    • Playwright end-to-end suite
    • Automated accessibility checks
  6. 6

    Performance tuning before launch

    We measure before we optimise. React DevTools Profiler shows which components re-render and why. A bundle analyser shows which libraries make the app heavy. Typical fixes are code splitting by route with lazy loading, virtualising long lists, replacing heavy date or chart libraries, and moving expensive work out of render. Where the React Compiler is enabled, it removes much of the need for manual memo and useCallback calls.

    What you get

    • Profiling report
    • Bundle size budget
    • Measured before and after numbers
  7. 7

    Release, monitoring and support

    We ship through your CI, usually GitHub Actions, to Vercel, Netlify, Cloudflare Pages, AWS or your own servers. Feature flags let us release to a small group first. Sentry or a similar tool captures front-end errors with source maps, and we watch Web Vitals from real users after each release. After launch we stay on for fixes, upgrades and new features, with daily updates and a weekly summary.

    What you get

    • CI/CD pipeline
    • Error and Web Vitals monitoring
    • Post-launch support plan

Technical expertise

React development expertise beyond the basics

Any developer can write a React component. The difference shows on large apps, after months of changes. This is where our engineers focus.

State management that stays simple

Most React state problems come from treating server data like local state. We keep data from your API in TanStack Query or RTK Query, which handles caching, refetching and loading states for you. URL state, such as filters and page numbers, lives in the URL so links can be shared. Only true app-wide state, like the current user or theme, goes into Zustand, Redux Toolkit or context. This removes whole categories of bugs.

Rendering performance on big screens

Dashboards with hundreds of rows and live updates can freeze if every change re-renders everything. We keep state close to the components that use it, split large contexts, and virtualise long lists with TanStack Virtual. We use transitions so typing in a search box never feels slow, and we move heavy calculations to Web Workers when needed. We check every fix with the Profiler rather than guessing.

Accessibility built into components

If the button, dialog and menu components are accessible, every screen built from them starts accessible. We manage focus when dialogs open and close, support full keyboard navigation, announce updates to screen readers with live regions, and respect reduced motion settings. We test with axe in CI and by hand with VoiceOver and NVDA, aiming for WCAG 2.2 AA.

Testing strategy that survives refactoring

Tests that check internal state break every time code is tidied, so teams stop writing them. We query by role and label in React Testing Library, the same way a screen reader user finds things. We mock the network with Mock Service Worker, not individual functions. A small set of Playwright tests covers the money paths in real browsers. The result is a suite that catches real regressions and rarely needs rewriting.

Type safety from API to UI

We use strict TypeScript and generate types from your OpenAPI, GraphQL or tRPC schema instead of writing them by hand. Form schemas in Zod are shared between validation and types. When the back end changes a field, the build fails in the exact places that need updating. This is one of the cheapest ways to prevent production bugs in a large React codebase.

Security in the browser

We avoid dangerouslySetInnerHTML or sanitise with DOMPurify when rich HTML is unavoidable. Tokens are kept in secure, HTTP-only cookies rather than local storage where possible, and a Content Security Policy limits what scripts can run. We never put secret keys in front-end code, because anything shipped to the browser is public. Dependencies are kept patched with Renovate or Dependabot.

FAQ

Hire React developers: frequently asked questions

Should my new project use plain React with Vite or Next.js?

Use plain React with Vite when your app sits behind a login, SEO does not matter, and you want the simplest possible deploy as static files on a CDN. Dashboards and internal tools are good examples. Choose Next.js when you need public pages that rank in search, fast first loads, or server-side logic in the same project. Our React developers work in both, and we will recommend one on the free consultation after hearing about your product.

Can you take over and fix an existing React codebase?

Yes. We start with a codebase audit in the first week covering structure, dependencies, bundle size, test coverage and the parts that cause the most bugs. Then we agree a plan that mixes new features with clean-up, so the product keeps moving. We usually add tests around fragile areas first, then refactor them in small, reviewed pull requests rather than pausing everything for a rewrite.

Do your React developers use Redux?

When it is the right tool. Redux Toolkit is still a solid choice for apps with complex client-side state, and many existing codebases depend on it. For new work we usually keep server data in TanStack Query or RTK Query and use lighter tools like Zustand or context for the small amount of global state left. If you already use Redux, we work with it and clean it up rather than replacing it for the sake of it.

How much does it cost to hire a React developer?

Cost depends on the size and complexity of the front end, whether you need a design system, how many API integrations there are, your timeline, and whether you need one developer or a small team. Joining an existing app is different from building a new one. We give you a free, fixed quote after a short call, so you know exactly what to expect before work starts.

Can you build a design system for several products?

Yes. We build component libraries on accessible primitives like Radix UI or React Aria, styled with design tokens that match your Figma files. Components are documented in Storybook, tested with React Testing Library and visual regression tests, and published as a versioned npm package so each product can upgrade at its own pace. We also write usage guidelines so other teams build with the components correctly.

How do you make React apps accessible?

We build accessibility into the shared components, so every screen inherits it. That means semantic HTML, proper labels, focus management in dialogs and menus, full keyboard support and enough colour contrast. We run axe checks automatically in CI and Playwright, and test key flows by hand with screen readers such as VoiceOver and NVDA. The target is WCAG 2.2 AA, which most enterprise and public sector buyers ask for.

Can you migrate our app from Create React App or class components?

Yes. Create React App is no longer recommended for new projects, and most teams move to Vite or Next.js. We migrate the build tooling first, keeping the app working, then convert class components to function components and hooks where it adds value. JavaScript files can move to TypeScript gradually. Each step ships separately, so there is never a long freeze on new features.

Do you also build React Native mobile apps?

Yes, through our React Native team. React and React Native share the same component model, hooks and many libraries, such as TanStack Query and Zustand. That means business logic, API clients and types can often be shared between your web app and your mobile app in a monorepo. If you need both, we can staff a team that covers web and mobile together.

How will I know what my React developer is working on?

You will see their work in your own tools. Tickets move across your board, pull requests appear in your repository with a description and preview link, and the developer posts a short daily update in your chat. Each week you get a summary of what shipped, what is planned next and any risks. You can join stand-ups or check in whenever you like.
