NestJS

NestJS is a progressive Node.js framework for building efficient, reliable, and scalable server-side applications. It uses TypeScript and combines elements of object-oriented programming, functional programming, and reactive programming. The framework is designed to help developers create highly testable, maintainable, and extensible applications.

It is primarily used for developing backend services, APIs, and microservices. NestJS is suitable for developers and teams looking for a structured and opinionated framework that provides a solid foundation for enterprise-grade applications, drawing inspiration from Angular's architectural patterns.
