What we build with Node.js
Node.js is the backend behind most of the systems JK Tech Hub delivers from Rajkot. It sits under our React, Next.js, Flutter and React Native front ends, and it is what we use when a client needs an API that other software will call. Common projects:
- REST and GraphQL APIs for mobile apps and web applications, with authentication, roles and rate limiting built in.
- Backends for SaaS products: multi-tenant data, subscription billing, usage metering and webhooks.
- Real-time services such as order tracking, chat, live dashboards and notifications over WebSockets.
- Integration layers that connect an ERP, accounting system or marketplace to each other, including GST e-invoicing and payment gateway callbacks.
- Background workers for report generation, bulk imports, scheduled syncs and email or SMS delivery.
We build with TypeScript on Express or NestJS, PostgreSQL or MongoDB, Redis for queues and caching, and Docker for deployment. Every API ships with documentation and an automated test suite your team can extend.
When Node.js is the right choice, and when it is not
Node.js is the right choice when the workload is many concurrent, short requests: APIs, real-time features, streaming, and anything where the frontend is JavaScript and one language across the stack keeps the team small. It starts fast, scales horizontally without drama, and its package ecosystem covers almost every third-party service an Indian business needs, from payment gateways to WhatsApp messaging.
It is the wrong choice when:
- The core work is CPU-heavy: data science, machine learning pipelines, image or video processing at volume. Python is the better fit, often alongside a Node.js API.
- Your organisation already runs a large Java or .NET estate with operations staff trained for it. Adding a runtime for one service creates cost without clear benefit.
- The application is a simple content site. A CMS covers it without a custom backend.
Most of our projects use Node.js for the API and add a Python service only where analytics or AI features justify it. We will lay out that split, and the hosting it needs, in the proposal.
Cost and timeline for Node.js projects
A basic Node.js backend, meaning a REST API with authentication, a few resources and a database, starts at ₹40,000 and takes two to four weeks. A standard backend with roles, payments, third-party integrations, background jobs and documentation starts at ₹1,25,000 and takes six to twelve weeks. Enterprise work such as microservices, high-throughput real-time systems or replacing a legacy backend while keeping the old one running starts at ₹4,00,000 and runs twelve to twenty weeks.
What changes the price is the number of entities and endpoints, the integrations, the data migration from any existing system, and non-functional requirements such as audit logs, uptime targets and load testing. Hosting on AWS, a VPS or your own server is set up as part of the project, with the monthly infrastructure cost estimated up front.
Quotes are fixed-price with milestone payments, include three months of bug-fix support and can continue as a monthly retainer for monitoring and patches. Overseas clients are quoted in their own currency; see the international page.
