10NestJS is a progressive Node.js framework for building efficient and scalable server-side applications. It uses TypeScript by default, supports both Express and Fastify, and provides an out-of-the-box application architecture inspired by Angular. NestJS combines elements of OOP, FP, and FRP, making it ideal for building enterprise-grade applications.
