Latest stable: 22 LTS
- Same language front + back
- Massive talent pool
- Strong async story
- Cloud-native
Node.js powers the backend of countless modern products, from real-time APIs and BFFs to streaming pipelines and CLI tools. We use it across NestJS, Fastify and Express stacks.
What Node.js does well
Async I/O
Handle thousands of concurrent connections with a small memory footprint.
NPM ecosystem
Two million packages cover ORMs, queues, auth, payments and more.
TypeScript-ready
First-class TS via tsx, Bun, or built-in type stripping in modern Node.
Streaming APIs
Server-Sent Events, WebSockets and HTTP/2 push out of the box.
Workers + clusters
Use worker threads for CPU-bound tasks; cluster across cores at scale.
Where teams use Node.js
REST + GraphQL APIs
NestJS, Fastify or Apollo with rate-limiting, caching and observability.
Real-time apps
Chat, collaboration, live dashboards via Socket.IO or WebSockets.
Serverless functions
AWS Lambda, Vercel Functions and Cloudflare Workers run Node natively.
