NestJS is a Node.js framework for building scalable and maintainable server-side applications, using TypeScript and a modular architecture. It supports dependency injection, middleware, and tools like WebSockets and GraphQL. To get started, install the NestJS CLI and create a new project. The blog walks through building a REST API with controllers and services, demonstrating how to handle user data with CRUD operations. It also covers middleware for logging and input validation using DTOs and class-validator. NestJS simplifies the development of scalable applications with a clean and organized structure.
