Clean, maintainable, scalable React codebases
React is the most widely adopted JavaScript library for building user interfaces — used by companies from startups to Fortune 500. Its component model, rich ecosystem, and flexibility make it the right choice for everything from marketing sites to complex web applications.
MarkRenown builds React applications with TypeScript, proper state management, clean architecture, and full test coverage. Whether you need a React SPA, a dashboard, or a component library, we deliver production-ready code that your team can maintain and scale confidently.
React Apps Built
TypeScript Codebase
Single-page applications, multi-step forms, data-rich portals, and interactive web tools built with React 18, TypeScript, and modern hooks.
Data visualization dashboards with Recharts or Chart.js, role-based access control, real-time data updates, and clean table/filter interfaces.
Custom, branded design system and component library documented in Storybook — enabling consistent, reusable UI across your entire product suite.
Bundle size reduction, lazy loading, memoization, virtual scrolling, and code-splitting to eliminate performance bottlenecks in existing React apps.
Concurrent features, automatic batching, useTransition, useDeferredValue — fully typed with TypeScript strict mode for maintainable, scalable codebases.
Zustand for lightweight global state, Redux Toolkit for complex state, TanStack Query for server state — chosen based on your specific application needs.
File-based or code-based routing with nested routes, lazy loading, protected routes, and breadcrumb generation using React Router 6 data APIs.
Utility-first styling with Tailwind CSS combined with headless, accessible shadcn/ui components — fast to build, easy to customize, production-ready.
Unit tests for utilities, integration tests for components, and end-to-end tests with Playwright — ensuring confidence in every deployment.
REST API integration with Axios or fetch, GraphQL with Apollo Client or URQL, real-time updates with WebSockets or React Query subscriptions.
Challenge: A logistics platform needed an operations dashboard — real-time shipment tracking, driver assignment, route optimization data visualization, and financial reporting — all within a single interface used by 120+ daily active operations managers.
Solution: Custom React 18 + TypeScript dashboard with Zustand state management, real-time WebSocket updates, Recharts data visualization, role-based access (admin/manager/agent), and complex filter/export interfaces.
Results:
Less Report Time
Dashboard Load
Fewer Errors
Daily Users
React excels at: interactive single-page applications (SPAs), admin dashboards with complex data visualization, portals with authentication and role-based access, real-time applications with WebSocket data, and multi-step forms or wizards. For public-facing websites that need SEO, we pair React with Next.js for server-side rendering.
Yes — always. TypeScript is our default for all React projects. It catches errors at development time rather than runtime, makes refactoring safe, improves IDE autocomplete and navigation, and makes the codebase significantly easier for teams to maintain and scale. The overhead of setting up TypeScript is minimal compared to the long-term benefits it provides.
React application development costs in India depend on scope. A simple React SPA costs ₹50,000–₹1,50,000. A React dashboard with backend API integration costs ₹1,50,000–₹4,00,000. A full-scale SaaS React application costs ₹4,00,000–₹15,00,000+. MarkRenown provides detailed project estimates after a free technical scoping session.
Yes. We have experience migrating applications from Angular, Vue.js, jQuery, and legacy frameworks to modern React + TypeScript. We use a phased approach — starting with critical pages and migrating incrementally to minimize disruption. For each migration, we start with a technical audit to understand the existing architecture and plan the migration path correctly.
Yes. We write unit tests for utilities and custom hooks (Vitest), integration tests for component interactions (React Testing Library), and end-to-end tests for critical user flows (Playwright). Test coverage targets are defined at project start — typically 70–80% for business-critical applications. Testing is built into our development process, not added at the end.
