FAQ

 About Our Node.js Development Services

Do you offer Node.js microservices consulting?

>

Absolutely. Most of our backend work now follows a microservices-first approach, and Node.js is a natural fit for it. We don’t just design microservices, we evaluate your domain boundaries, identify service split logic, and choose whether to use Express.js, Fastify, or even gRPC depending on latency and throughput goals. We also help set up inter-service communication, service discovery, and observability tooling (like OpenTelemetry) from day one to avoid scaling pain later.

What is Node.js primarily used for?

>

Node.js shines in situations where concurrency, I/O, and real-time interaction are critical.That means real-time dashboards, chat apps, streaming platforms, high-throughput APIs, and even edge server logic. It's the go-to backend when you need lightweight, scalable services without blocking threads especially for modern apps that talk to many services or users simultaneously.

How much does it cost to hire a Node.js developer?

>

It depends on experience, geography, and the nature of the project but here’s a realistic range:Junior Node.js devs typically range from $25–$40/hr offshore. For mid to senior-level engineers with experience in performance tuning, microservices, or DevOps, you're looking at $50–$100/hr depending on region and scope. For a full agile team (PM, Devs, QA, DevOps), monthly retainer models typically start around $15K–$30K depending on team composition and sprint velocity.

Do You Support Node.js Deployments?

>

Yes, and frankly, we believe DevOps is non-optional for serious Node.js delivery.We set up CI/CD pipelines for automated testing, Dockerized environments for parity, and Kubernetes (or serverless, depending on scale) for deployment. Tools like PM2 for process management and custom health check endpoints are baked into every build. Our DevOps team also helps with log aggregation, monitoring (e.g., Grafana, New Relic), and auto scaling strategies tailored for Node.js apps.

What Apps Can Be Made with Node.js?

>

We've built everything from fintech scoring APIs to live logistics tracking platforms using Node.js.It’s ideal for microservices-based SaaS products, collaborative tools (think Google Docs-style editors), single-page application backends, API gateways, real-time data visualizations, and even some IoT control panels. If it needs speed, modularity, and responsiveness Node.js is likely a fit.
