Our Node.js Development Process

We build Node.js backends that are fast, secure, and maintainable.

System Design

System Design

Architecture

Designing API contracts (OpenAPI), database schema, authentication strategy, and infrastructure architecture. Microservices vs monolith decision.

Project Setup

Project Setup

Foundation

Express, Fastify, or NestJS setup with TypeScript. ESLint, Prettier, and testing framework configuration. Docker and CI/CD setup.

API Development

Building Services

RESTful or GraphQL API implementation with proper error handling, validation (Zod/Joi), and documentation.

Database & Caching

Database & Caching

Data Layer

PostgreSQL/MongoDB integration with Prisma/Mongoose. Redis for caching and session management. Query optimization.

Security & Auth

Security & Auth

Protection

JWT/OAuth2 authentication, rate limiting, input validation, and security headers. OWASP guidelines implementation.

DevOps & Scaling

Production

Docker containerization, Kubernetes orchestration, auto-scaling configuration, and monitoring with Datadog or New Relic.

Why Node.js for Your Backend?

About image 1
About image 2

Node.js processes 1.7 billion npm downloads weekly—it's the backbone of modern web development. Its non-blocking I/O handles thousands of concurrent connections efficiently. With TypeScript, you get type safety without sacrificing JavaScript's flexibility. Companies like Netflix reduced startup time by 70% after switching to Node.js.

Expert Answers to Your Questions

Node.js Development FAQs

Everything you need to know about our Node.js development services.

Absolutely. Node.js powers Netflix (1 billion hours streamed monthly), PayPal (100% faster response times), and LinkedIn. With TypeScript and frameworks like NestJS, Node.js provides enterprise structure. We've built Node.js backends handling 10M+ daily requests for enterprise clients.

We implement: input validation (Zod/Joi), parameterized queries (SQL injection prevention), JWT/OAuth2 authentication, rate limiting, helmet.js for security headers, CORS configuration, and regular npm audit. All APIs follow OWASP security guidelines.

PostgreSQL for relational data (with Prisma ORM), MongoDB for document data (with Mongoose), Redis for caching and sessions. We choose based on your data structure and query patterns. Most projects use PostgreSQL + Redis combination effectively.

Yes! Node.js excels at real-time with its event-driven architecture. We build: live chat, notifications, collaborative editing, live dashboards, and gaming backends. Socket.io or ws library with Redis pub/sub for multi-server deployments.

We optimize through: async/await patterns, event loop monitoring, database query optimization, caching strategies (Redis), load balancing, and horizontal scaling. We use APM tools (New Relic, Datadog) for monitoring and conduct load testing before launch.
