Have you used NestJS in your projects?

NestJS is a progressive framework for Node.js built on top of Express (or Fastify), which uses TypeScript and is focused on creating scalable server-side applications with a modular and decorator-based architecture.

If you have used NestJS, you are likely familiar with concepts such as controllers, services, modules, dependency injection, and middleware. NestJS simplifies code organization and integration with various libraries.

Example of a simple controller in NestJS:

import { Controller, Get } from '@nestjs/common';

@Controller('cats')
export class CatsController {
  @Get()
  findAll(): string {
    return 'This is a list of all cats';
  }
}

If you haven't used NestJS, it is a good framework to learn, especially if you want to write server-side code in TypeScript with a clear architecture.
