FAQs

Frequently Asked Questions About Node.js Development

When should we choose Node.js for our backend?

Node.js is ideal for real-time applications, APIs, and services with high I/O — like chat, streaming, and data-heavy platforms. Its event-driven model handles many concurrent connections efficiently, and the shared JavaScript language speeds up full-stack development.

Do you use TypeScript or plain JavaScript?

We build in TypeScript by default. It gives you safer refactoring, better tooling, and fewer production bugs — while still compiling to standard Node.js.

Can you scale our existing Node.js application?

Yes. We profile bottlenecks, improve concurrency, add caching and load balancing, and refactor toward microservices or serverless when your traffic demands it.

Do you provide support after launch?

We offer ongoing maintenance covering bug fixes, dependency updates, performance monitoring, and new features — so your backend stays healthy long after launch.
