NestJS

Nest is a framework for building efficient, scalable Node.js server-side applications. It uses modern JavaScript, is built with TypeScript (preserves compatibility with pure JavaScript) and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming).

Under the hood, Nest makes use of Express, but also provides compatibility with a wide range of other libraries, like Fastify, allowing for easy use of the myriad of third-party plugins which are available.
