Why Node.js?
Node.js lets you write backend in JavaScript and TypeScript. One language, one team, one ecosystem. This simplifies communication, speeds up development, and lowers costs. For us, Node.js is a natural choice because our entire stack speaks the same language.
What Node.js gives you
I/O performance
Event-driven, non-blocking I/O. Handles thousands of concurrent connections without spawning new threads.
One language
TypeScript on frontend and backend. Smaller team, shared types, faster development.
npm ecosystem
The largest package registry in the world. A proven solution for every problem.
Scalability
From prototype to millions of users. Clustering, load balancing, microservices.
