# Getting Started with NestJS
As I started building larger backend applications, I realized that managing routes, services, authentication, and databases in plain Express.js could become difficult as projects grew. That's when I discovered NestJS.
NestJS is a progressive Node.js framework built with TypeScript. It provides a structured architecture inspired by Angular and helps developers build scalable and maintainable server-side applications.
One of the features I appreciate most is its modular architecture. Instead of placing all logic in a single file, NestJS encourages separating features into modules, controllers, and services. This makes projects easier to understand and maintain.
While learning NestJS, I explored concepts such as dependency injection, middleware, guards, interceptors, and custom decorators. I also integrated PostgreSQL using TypeORM and implemented JWT-based authentication systems.
NestJS has significantly improved the way I approach backend development. It allows me to focus on writing clean business logic while providing a solid foundation for scalable applications. Today, it is one of my preferred technologies for building APIs and backend services.
