What is Node.js?
Node.js is an open source, cross-platform JavaScript runtime that executes JavaScript code outside a web browser. Its event-driven, non-blocking I/O model makes it efficient for building scalable network applications.
Why We Use Node.js
Node.js enables rapid development with JavaScript everywhere:
- Full-Stack JavaScript: Same language on frontend and backend
- Non-Blocking I/O: Event loop handles thousands of concurrent connections
- NPM Ecosystem: Over 2 million packages for any use case
- Fast Development: Quick iterations with familiar JavaScript
- JSON Native: Perfect for REST APIs and JavaScript clients
Our Node.js Expertise
We build production Node.js applications:
- REST APIs: Express, Fastify, and NestJS frameworks
- Real-time Apps: Socket.io and WebSocket implementations
- Serverless: AWS Lambda and Cloud Functions
- CLI Tools: Command-line utilities and build scripts
- BFF Patterns: Backend-for-frontend aggregation layers
When to Choose Node.js
Node.js excels for:
- Real-time applications (chat, gaming, collaboration)
- APIs serving JavaScript/mobile clients
- Microservices requiring fast startup times
- Serverless functions and event-driven architectures
- Teams sharing code between frontend and backend
