NestJS is a progressive Node.js framework for building efficient, scalable server-side applications with TypeScript, a modular architecture, and strong dependency injection.
Overview
NestJS brings structure to Node.js backends with modules, controllers, providers, and a powerful dependency-injection container. Built with TypeScript first, it supports REST and GraphQL APIs, WebSockets, guards, interceptors, and pipes, and integrates cleanly with ORMs and message queues for enterprise-grade services.
How I Use NestJS
I use NestJS to build maintainable APIs with clear module boundaries — wiring controllers, services, DTO validation, and auth guards, and layering in interceptors for logging and error handling. Its opinionated structure keeps larger codebases organized and testable.
Why NestJS?
NestJS gives Node backends the architecture they usually lack. Its DI, typing, and module system make features easy to reason about and scale, which is why I reach for it on larger server-side projects.
