What is NestJS and why use it?▾
NestJS is a Node.js framework that provides an opinionated, modular architecture inspired by Angular. It's built with TypeScript and adds structure, dependency injection, and testability that plain Express lacks — ideal for larger backends.
Is NestJS built on Express?▾
By default NestJS runs on top of Express, but it can also use Fastify for higher performance. You get the framework's structure while still being able to drop down to the underlying platform when needed.
