Question 1

How much does Node.js backend development cost?

Accepted Answer

Most Node.js API projects reach production within 8-16 weeks, depending on scope and integration complexity. An API backend for a mobile app with 10-20 endpoints typically runs $15,000 to $40,000. A microservices platform with 5-10 services sits in the $50,000 to $150,000 range. Enterprise backends with complex integrations, auth systems, and real-time features can run $100,000 to $300,000 or more. Our architecture consultation is free and scopes your specific project.

Question 2

Is Node.js good for enterprise applications?

Accepted Answer

Yes. Netflix, LinkedIn, PayPal, Uber, and Walmart run production Node.js backends processing billions of API requests daily, confirming enterprise readiness. The difference between a reliable enterprise system and a fragile one comes down to architecture: strict TypeScript, NestJS for enterprise patterns, and microservices designed for independent scaling. Node.js handles I/O-heavy workloads exceptionally well. For CPU-heavy computation, we pair it with services written in Python or Go. Node.js often serves as the API gateway in [AI engineering](/services/ai-engineering/) pipelines.

Question 3

Should I use Express, NestJS, or Fastify?

Accepted Answer

Express works well for smaller projects or teams that prefer minimal structure and maximum flexibility. NestJS fits enterprise applications where modularity, dependency injection, and standardized patterns matter. Fastify is the choice when raw HTTP throughput is the priority - benchmarks consistently show it handling 2-3x more requests per second than Express. We help you choose based on your team's experience and your project's actual requirements.

Question 4

Node.js vs. Python for backend development?

Accepted Answer

Node.js excels at I/O-heavy, concurrent workloads like APIs, real-time apps, and microservices. Python excels at data processing, ML/AI pipelines, and scientific computing. Many modern systems use both: Node.js for the API layer and Python for data processing behind it. We build in both and help you decide based on your actual workload, not framework popularity. If your workload is AI/ML-heavy, explore our [Python development services](/technologies/python/).

Question 5

Can Node.js handle high traffic?

Accepted Answer

Yes. The event-driven, non-blocking architecture handles thousands of concurrent connections per process. With clustering and proper load balancing, a well-built Node.js service handles 10,000+ requests per second. PayPal reported 35% faster response times after migrating from Java to Node.js for their checkout flow. The ceiling is architecture, not the runtime.

Question 6

How do you handle Node.js security?

Accepted Answer

We follow OWASP guidelines and build security into every API from the start. That means input validation with Zod or Joi, HTTP header hardening with Helmet.js, rate limiting on all public endpoints, and automated dependency scanning through npm audit and Snyk. Authentication and authorization enforced at every endpoint, not just the obvious ones. Security is not a feature we add before launch. It is part of how we write code.

Question 7

Can you migrate our existing backend to Node.js?

Accepted Answer

Yes. We have migrated PHP (Laravel), Ruby on Rails, and legacy Express backends to modern Node.js architecture. The approach is always incremental. We identify the highest-value services for migration first, run old and new systems in parallel, and cut over service by service. No big-bang rewrites. Your application stays live throughout the process.

Question 8

Do you work with US-based teams from India?

Accepted Answer

Yes. Our engineering team is based in Mumbai with working hours that overlap US EST and PST. We have delivered backend systems for US-based clients and communicate via Slack, daily standups, and weekly demos. Same tools, same cadence, different timezone.

Question 9

How does NestJS compare to Express and Fastify for Node.js projects?

Accepted Answer

Express is the most widely used Node.js framework, with a minimal footprint and a massive ecosystem of middleware. It works well for straightforward APIs where the team prefers to assemble their own stack. NestJS builds on top of Express (or optionally Fastify) and adds a structured architecture with dependency injection, modules, and decorators. It suits larger backends with multiple developers who benefit from enforced patterns. Fastify is the performance-focused option, handling roughly 30% more requests per second than Express in benchmarks, with built-in schema validation and structured logging. At Procedure, we select the framework based on project needs: Express for most 2-3 developer API projects, NestJS for enterprise backends with 5+ developers, and Fastify for high-throughput services where raw performance matters.

Question 10

What should I look for when evaluating a Node.js development company?

Accepted Answer

Five things matter. First, ask what Node.js version the team standardizes on. Companies running current LTS with automated dependency scanning take security seriously. Second, check if they use TypeScript by default. Plain JavaScript in production backends is a maintainability risk. Third, ask for a real project example showing how they handled high concurrency or real-time requirements. Node.js expertise shows in architecture decisions, not feature lists. Fourth, ask about their framework selection process. A company that defaults to Express for everything has likely not evaluated alternatives like NestJS or Fastify. Fifth, understand the handoff process: do you get full code ownership, documentation, and runbooks? We answer all five of these transparently on this page.
