Node.js Development

How we use it

Node.js is our go-to for API backends paired with React or Next.js frontends. We use Fastify for high-throughput APIs, NestJS for structured enterprise backends, and Express for lean integration services. Every production Node.js project is written in strict TypeScript.

SaaS backends

Real-time APIs

Integration microservices

Why now

Node.js powers the backends of Netflix, LinkedIn, Uber, and PayPal and is experiencing a significant resurgence. Node.js 22 LTS, released in 2024, introduced native TypeScript stripping (run .ts files directly without a build step), a mature built-in test runner, and performance improvements that close the gap with Bun and Deno - eliminating many reasons teams historically chose alternative runtimes. With JavaScript and TypeScript now usable end-to-end from database client (Prisma) to API layer (Fastify) to frontend (Next.js), teams that unify their stack on Node.js gain substantial developer efficiency over polyglot setups.

Fit analysis

Is this right for you?

Honest breakdown of where Node.js Development shines — and where it doesn't. Pick the right tool.

When to choose this

Right fit scenarios

You are building a REST or GraphQL API for a SaaS product or mobile application where development velocity and JSON handling performance are the primary concerns

Your application needs real-time features - WebSockets, live notifications, collaborative editing, presence indicators - where Node's event-driven non-blocking I/O model is purpose-built

Your frontend is React or Next.js and you want a unified JavaScript/TypeScript stack where any developer can work across both layers without context-switching between languages

You need integration microservices that connect third-party APIs, process webhooks from Stripe, Shopify, or Twilio, and orchestrate data between multiple external systems

You are building an AI-powered product and need to integrate with LLM APIs (OpenAI, Anthropic) - the JavaScript SDKs for these platforms are the best-maintained and most frequently updated in the ecosystem

Honest limitations

Not the best fit if…

CPU-intensive computation tasks - image and video processing, scientific computing, or machine learning training - where Python or Go have better concurrency primitives and mature libraries

Teams with primarily PHP or Python expertise who will own long-term maintenance - using an unfamiliar runtime creates operational risk and hiring constraints

Applications requiring a highly opinionated, batteries-included framework with built-in ORM, auth scaffolding, and admin panels out of the box - Laravel or Django provide more in this regard

Heavy relational data processing with complex SQL queries and multi-table transactions at scale, where Python's SQLAlchemy or Laravel's Eloquent ORM have more mature tooling

Common questions

You're probably wondering

How long does a Node.js backend take to build?

A Node.js REST API with authentication, CRUD endpoints, third-party integrations, and basic deployment takes 6–10 weeks. A full SaaS backend with complex business logic, queuing, webhooks, multi-tenant architecture, and monitoring takes 14–24 weeks depending on scope.

Node.js vs Laravel - which should I choose?

Choose Node.js if your team is JavaScript-first, you need real-time features, or you are building an API-only backend for a React/Next.js frontend. Choose Laravel if you need a batteries-included framework with a strong ORM, built-in auth scaffolding, queue management, and your team has PHP experience. For most product teams building a modern SaaS, Node.js with TypeScript is the stronger long-term choice.

What Node.js frameworks do you use?

We use Fastify as our default for API services - it is the fastest Node.js HTTP framework, has excellent TypeScript support, and generates OpenAPI specs natively. For structured enterprise backends with multiple modules and dependency injection, we use NestJS. For lean integration layers and webhooks, Express with TypeScript is still effective and well-understood by most Node.js developers.

Do you use TypeScript with Node.js?

Always, for production projects. Node.js 22 can now strip TypeScript types natively, eliminating the build step in development. We configure strict TypeScript, ESLint with recommended rules, and Zod for runtime request validation. This combination catches the majority of bugs before they reach staging.

How much does Node.js development cost in India?

A mid-complexity Node.js API starts at ₹5–8 lakh. Full backend systems with authentication, payments, notifications, and multi-tenant support range from ₹12–25 lakh. Senior Node.js / TypeScript developers in India bill at ₹3,000–6,000/hour.

Can Node.js handle high traffic?

Yes. Node's non-blocking event loop handles thousands of concurrent connections efficiently. LinkedIn handles 600 million connections with Node. For high-throughput workloads, we pair Node with Nginx as a reverse proxy, horizontal scaling via Docker and ECS or Kubernetes, and Redis for session management and caching.

How do you handle background jobs and queues in Node.js?

We use BullMQ with Redis for job queues - it handles scheduled jobs, retries with exponential backoff, priority queues, and job progress tracking. For simpler use cases, we use PostgreSQL-backed queues via pg-boss, which eliminates the need for a separate Redis instance. All queue workers are deployed as separate Docker containers for independent scaling.
