React is used by 44.7% of professional developers worldwide more than Angular, Vue, and Svelte combined. React 19 and Next.js 16 are the current production stack. The React Compiler is now at v1.0, and Create React App has been formally sunset. The stack has moved on. KiwiCommerce provides UK-based React.js and React Native developers who work on current versions, build to current standards, and bring eCommerce depth that a general React agency does not have.
The gap between a React developer who knows the library and one who does not builds production React code that scales more widely than most hiring decisions account for. TypeScript is not optional in 2026, around 80%of serious React code bases use it. React Server Components require a fundamentally different mental model from client-side React. And a developer who understands eCommerce behaviour alongside React is a different hire from one who does not.
Get In TouchReact 19 is the current production. Our developers work with React Server Components, the Actions API, and the React Compiler at v1.0 as a baseline, not as features to explore later.
round 80% of serious React codebases in 2026 use TypeScript. Our developers write TypeScript as standard, not as an option for projects that specifically ask for it.
KiwiCommerce's background is in Shopify, Magento, and WooCommerce. React.js and headless eCommerce built by the same team means product pages, checkout flows, and Core Web Vitals are handled correctly, not adapted from generic UI patterns.
Most React agencies focus on either web or mobile. We provide both React.js web developers and dedicated React Native app developers. Single partner, no coordination gap between platforms.
React.js and React Native share a creator (Meta), a language (JavaScript and JSX), and a component-based architecture. They serve different platforms and require different specialists. Knowing which one your project needs and whether the developer you are hiring works on the current versions matters more in 2026 than it did two years ago.
React.js: React 19 is production-stable. The React Compiler reached v1.0 in October 2025, removing the need for manual memoisation with useMemo and useCallback. React Server Components are now the standard architecture in Next.js 16. Create React App has been formally sunset. New projects should start on Vite or Next.js. The developer who built SPAs with Create React App in 2019 and has not moved on is working with an outdated mental model. Next.js 16 is the standard framework for 67% of new enterprises' React projects, enabling React Server Components, server-side rendering, API routes and edge functions in a unified architecture.
React Native: The New Architecture (Fabric renderer, Hermes engine) is now required in React Native 0.82. It significantly narrows the performance gap with fully native apps for the use cases where React Native is appropriate, such as mobile commerce, delivery platforms, dashboards, fintech, and business applications. A React Native app is not a web app wrapped in a browser view. It installs from the App Store or Google Play and renders genuine native components on each platform.
KiwiCommerce's background in eCommerce across Shopify, Magento, and WooCommerce means our React developers bring genuine platform knowledge to headless storefronts, product page performance, and checkout conversion, not generic UI patterns adapted for retail. With 250+ projects delivered since 2016, we have built React.js web applications, Next.js full-stack products, React Native mobile apps, and headless eCommerce frontends across real commercial deadlines.
Discuss Your Project2+ Experience Years
Builds React components to a defined spec with senior oversight. Understands JSX, props, state, and basic hooks (useState, useEffect). Implements UI screens from a Figma design within an existing codebase and component library. Not suited for architecture decisions, state management design, or TypeScript-heavy codebases without guidance. Best suited for contained feature work within a project that has senior technical direction throughout.
5+ Experience Years
Owns complete React features end-to-end. Comfortable with TypeScript, advanced hooks, state management libraries (Redux, Zustand, TanStack Query), REST and GraphQL API integration, and responsive UI implementation. Works independently on mid-complexity React.js web applications and Next.js projects. Writes code other developers can read, maintain, and extend without a briefing.
7+ Experience Years
Designs React application architecture from the ground up. Deep understanding of React 19 patterns, Server Components, the Actions API, and the React Compiler at v1.0. Experienced with Next.js full-stack patterns, performance profiling, bundle optimisation, accessibility, and long-term codebase maintainability. Makes the architectural decisions that determine whether a React application scales cleanly or becomes a rewrite project in eighteen months.
5+ Experience Years
Specialist in building and maintaining cross-platform mobile apps using React Native. Works with the New Architecture (required in React Native 0.82), React Navigation, Expo and bare React Native workflows, native module integration, platform-specific styling, and App Store and Google Play submission. Understands the difference between React Native components and their web equivalents important for developers who have only built in React.js before.
5+ Experience Years
Combines strong React.js frontend skills with backend proficiency in Node.js, PHP, or Python. Builds complete web applications using Next.js as a full-stack framework, REST and GraphQL API design, database integration, and deployment pipelines. Reduces coordination overhead between frontend and backend on builds where both are owned by the same person or under tight technical leadership.
4+ Mixed levels
Senior React Native engineers who lead mobile builds from architecture through to App Store and Google Play release: state management, push notifications, device API integration, in-app payments, performance profiling, and app store compliance. For businesses that need a full React Native app development agency arrangement rather than a single developer. Best suited for commercially critical mobile products with ongoing development needs.
Single-page applications, SaaS product frontends, interactive dashboards, and complex UI-heavy web products using React 19 with TypeScript, proper state management, and component architecture designed for maintainability. React Compiler v1.0 handles memoisation automatically, but only when the component structure is written correctly to take advantage of it.
Full-stack web applications using Next.js 16 with React Server Components, server-side rendering, API routes, edge functions, and optimised static generation. The standard architecture for 67% of new enterprise React projects. Our developers build full Next.js applications, not just the frontend layer, handling data fetching, authentication, and deployment on Vercel or AWS.
React.js and Next.js storefront development for headless Shopify (Storefront API), headless Magento (Adobe Commerce), and custom commerce backends. Our developers understand the eCommerce product page performance, checkout conversion, and Core Web Vitals, not just React component patterns applied to a retail context.
Cross-platform iOS and Android apps that share a codebase while rendering genuine native components using the New Architecture (required in React Native 0.82). Built with Expo or bare React Native, depending on project requirements. Handles App Store and Google Play submission, native module integration, push notifications, and in-app payment flows.
Diagnosing and resolving performance problems in existing React applications: unnecessary re-renders, bundle size, lazy loading, code splitting, and Core Web Vitals. Includes state management review, poor state architecture is one of the most common causes of React performance degradation, and generic profiling tools will not identify it without architectural understanding.
Migrating React applications from older versions (React 16, 17, 18) to React 19. Moving from Create React App now formally sunset, to Vite or Next.js. Assessing existing codebases for TypeScript adoption, React Server Component compatibility, and React Compiler readiness. Upgrades documented and staged so the existing application continues trading throughout the process.
There are a lot of React developers available. The question is whether they are building with the current stack, whether they understand your platform, and whether they are reachable when something needs resolving.
React 19 is the current production. Next.js 16 is the current framework. The React Compiler is at v1.0. Create React App is sunset. Developers who have not moved on from older patterns create technical debt from the first commit. Our developers work on current versions as a baseline, not as a specialism that needs to be specifically requested.
Building a headless Shopify storefront is different from building a marketing site. Product page rendering, checkout flow performance, inventory state management, and Core Web Vitals in a retail context are specific problems. Our React developers have built these with Shopify's Storefront API, headless Magento, and custom commerce backends, not by learning from the documentation.
Around 80% of serious React codebases in 2026 use TypeScript. Developers who treat it as optional create codebases that become harder to maintain every month. Our developers write TypeScript as standard. It catches entire categories of bugs at compile time, improves IDE tooling, and significantly reduces onboarding time when the next developer needs to pick up the code.
Most React agencies focus on web or mobile. KiwiCommerce provides both React.js web developers and dedicated React Native app developers. For businesses building or maintaining both platforms, that means a single technical partner, a shared codebase understanding, and no coordination gap between separate agencies managing web and mobile independently.
Every React developer is based in the UK. Standups happen at a sensible time. Questions get answers the same day. For projects with fast-moving development cycles or live applications that need a rapid response when something breaks, losing a working day between question and answer is not a delivery detail; it is a delivery risk.
Codebase handover documentation, TypeScript types, component architecture decisions recorded, and state management explained. At the end of every React project, the codebase can be picked up by the next developer without a three-hour briefing. This is not a default outcome with React development; it requires deliberate discipline from the first commit. Our developers apply that discipline as standard.

React.js is a JavaScript library for building web user interfaces. It runs in the browser and produces the HTML, CSS, and JavaScript that users interact with on websites and web applications. React Native is a framework for building cross-platform mobile applications for iOS and Android. It uses the same component model and JSX as React.js, but instead of rendering to the DOM, it translates components into native UI elements on each platform. They are not interchangeable. A React.js developer without React Native experience will need time to produce production-quality mobile apps.
React 19, released December 2024, is the current stable version. It introduced the React Compiler at v1.0 (which handles memoisation automatically without useMemo and useCallback), React Server Components at stable production quality, and the Actions API for server-side data mutations. 48.4% of daily React users are already on React 19. For new projects, React 19 is the correct choice. For existing applications on React 16, 17, or 18, upgrading is straightforward for most codebases and brings meaningful performance improvements.
Next.js is the most widely used React framework for production web applications 67% of new enterprise React projects are now built on it (Belitsoft 2026). It adds server-side rendering, static generation, API routes, edge functions, and full-stack patterns on top of React. React Server Components are enabled by default in Next.js 16 and are the standard architecture for new applications. Create React App, the previous default for React projects, was formally sunset in the State of React 2025 survey.
Yes to both. For businesses with an ongoing React.js development need, we provide a dedicated React.js developer on a monthly retainer. For React Native mobile apps in continuous development, we provide a dedicated React Native developer on the same basis. The dedicated model means the same developer works consistently on your codebase, building knowledge of the architecture and business logic over time. For larger projects, we provide a React.js development team or a full React Native app development agency arrangement.
Yes. React Native’s core purpose is cross-platform development, one codebase that runs on both iOS and Android. Our React Native developers build apps targeting both platforms, handle platform-specific styling, test on both operating systems, and manage submission to the Apple App Store and Google Play. Where a feature requires a device API not covered by React Native’s core or community packages, our developers integrate custom native modules. All React Native work is done on the current New Architecture required in React Native 0.82.
Yes, and this is where our eCommerce background makes a real difference over a general React agency. Our React.js developers have built headless storefronts for Shopify (using the Storefront API), headless Magento (Adobe Commerce), and custom commerce backends. They understand eCommerce-specific challenges: product page performance, checkout flow conversion, real-time inventory state management, and what Core Web Vitals mean in a retail context. These are not patterns adapted from general UI work; they are built from eCommerce delivery.
A freelance marketplace gives access to individual developers with no continuity, no account management, and no quality guarantee. You assess each candidate, manage the relationship, and carry the risk of inconsistent code quality across different hires. KiwiCommerce provides pre-assessed React.js and React Native developers with verified experience, managed as a single engagement with one point of contact. Code goes into version control. NDAs are signed as standard. If a developer changes, we manage the transition and knowledge handover.
Yes, TypeScript is standard on every React project we deliver, not something that requires a specific request. Around 80% of serious React codebases in 2026 use TypeScript. It catches entire categories of bugs at compile time, improves IDE tooling, makes refactoring safer, and significantly reduces the time a new developer needs to understand the codebase. Developers who treat TypeScript as optional in 2026 are producing codebases that will require more maintenance, not less, over the following twelve months.
Our UK-based React.js and React Native development team is ready to look at your project. Whether you need a dedicated React developer on a monthly retainer, a React Native app development agency for a mobile product, a React.js development team for a web build, or expert React developers for a headless eCommerce frontend, get in touch today.
