Nest is a progressive Node.js framework for building efficient, scalable, enterprise-grade server-side applications using TypeScript (while staying compatible with plain JavaScript).
Nest is a progressive Node.js framework for building efficient, scalable, enterprise-grade server-side applications using TypeScript (while staying compatible with plain JavaScript).Is this a framework or just a library of helpers?It's a full application framework, not a loose set of utilities: it enforces an opinionated architecture (modules, controllers, providers) inspired by Angular, and runs on top of Express by default while also supporting Fastify as a drop-in HTTP adapter.

Node.js 20 or later is required; TypeScript is the primary language Nest is built with, but it explicitly preserves compatibility with pure JavaScript.What's the catch compared to using Express directly?Nest adds an opinionated, Angular-style layer of modules, decorators, and dependency injection on top of Express/Fastify, which means more structure to learn upfront than writing raw Express routes.
