Node.js Backend & API Development
Production-grade Node.js backends. We build secure REST APIs, real-time socket connections, microservice layers, and serverless background workers.
What are custom Node.js backend services?
Node.js is an open-source, cross-platform JavaScript runtime environment designed to build scalable network applications. Custom Node.js development involves engineering high-throughput backend APIs, microservices, real-time communication layers, and background workers using non-blocking I/O event models.
High-Throughput Node.js API Backends
We write production-grade Node.js backend code. We specialize in asynchronous execution environments, REST/GraphQL development, custom websocket servers, and secure data sync pipelines.
Key Benefits of Our Node.js Backend
- Sub-100ms API Response: Asynchronous execution structures designed for maximum database and response speeds.
- Real-time Sockets: Built-in support for websocket nodes that scale natively using Redis adaptors.
- Unified JS Stack: Share types, utility functions, and developers between your React frontend and Node backend.
- Microservice Ready: Lightweight memory footprint, ideal for containerized Docker deployments in Kubernetes.
Technologies We Integrate
We build Node.js backends using NestJS, Express.js, TypeScript, PostgreSQL, MongoDB, Redis, Docker, and AWS.
Our Node.js Development Process
- Database Schema Scoping: Creating migrations, database relationships, and optimized query indices.
- API Specification Drafting: Creating Swagger/Postman API contracts before writing code.
- Asynchronous Coding: Implementing authentication layers, middleware, logs, and database pipelines.
- Containerization & CI/CD: Packaging apps inside Docker and configuring auto-deployments.
Estimated Pricing Range
Standard API integrations and lightweight Node.js backends start from ₹60,000 to ₹1,20,000. Heavy real-time servers and scalable multi-service backends range from ₹1,50,000 to ₹3,20,000.
Frequently Asked Questions
How do you structure Node.js apps?
We use NestJS for large enterprise systems that require strict TypeScript architectures, and Express or Fastify for lightweight APIs and microservices.
How do you handle horizontal scalability?
We deploy Node.js inside Docker containers coordinated by Kubernetes, using Redis for Pub/Sub websocket sync and state storage.
