React.js Development FAQs
1. What's the difference between React.js and Next.js?
React.js is a UI library for building components. Next.js is a framework on top of React that adds SSR, SSG, built-in routing, image optimisation, and API routes — making it ideal for SEO-sensitive public websites and web apps.
2. Should I use React or Next.js for my project?
If you need SEO (marketing sites, blogs, eCommerce), choose Next.js. If you're building an internal tool, dashboard, or SPA behind a login, plain React is fine. We recommend the right choice during the discovery call.
3. How long does a React.js project take?
A simple React SPA takes 3–6 weeks. A complex web application with backend integration takes 2–4 months. Our AI-powered workflow delivers 40-60% faster than traditional agencies.
4. How much does React.js development cost in India?
A simple React app starts from $3,000. A full-featured web application ranges from $8,000–$25,000. Enterprise platforms start from $25,000+. We provide detailed proposals after a free discovery call.
5. Do you use TypeScript for React projects?
Yes — TypeScript is our default for all React projects. It catches errors at compile time, improves IDE support, and makes large codebases significantly easier to maintain.
6. Can you integrate React with our existing backend?
Absolutely. We connect React/Next.js to any backend — REST APIs, GraphQL, Firebase, Supabase, or your existing PHP/Node.js server.
