Node.js Development FAQs
1. Why use Node.js for backend development?
Node.js uses a non-blocking, event-driven architecture — handling thousands of concurrent connections efficiently. Ideal for REST APIs, real-time apps, and microservices. It also allows JavaScript across the full stack (MERN).
2. When should I choose Node.js over PHP?
Choose Node.js when you need real-time features (chat, live notifications), high-concurrency APIs, or a JavaScript full stack. PHP/Laravel is often better for traditional web applications and CMS platforms.
3. How long does a Node.js API project take?
A simple REST API takes 2–4 weeks. A complete backend with auth, database, and integrations takes 6–12 weeks. Our AI-powered workflow delivers 40-60% faster than traditional agencies.
4. How much does Node.js development cost in India?
A simple Node.js API starts from $2,000–$5,000. A full backend platform ranges from $8,000–$25,000. Enterprise microservices start from $25,000+. Detailed proposals after a free call.
5. Do you provide API documentation?
Yes. Every API ships with Swagger/OpenAPI documentation and a Postman collection — making integration easy for your mobile app or frontend team.
6. Can you build a full MERN stack application?
Absolutely. We build complete MERN stack applications — MongoDB, Express, React, Node.js — from one team, ensuring tight frontend-backend integration.
