Nestjs

Progressive Node.js framework for scalable server-side applications

Overview

NestJS is a progressive Node.js framework for building efficient, reliable, and scalable server-side applications.\n\nIt is built with TypeScript (while supporting JavaScript) and combines architectural concepts such as OOP, FP, and FRP. Under the hood it uses Express by default and can optionally be configured to use Fastify.\n\nNestJS is a backend framework (not a UI rendering framework), so CSR/SSR/SSG/ISR rendering modes are not applicable as framework features.
