NestJS CRUD Application.

This is a NestJS application that provides a RESTful API for performing CRUD (Create, Read, Update, Delete) operations on a User entity. The application uses MySQL as the database and includes modules for database connectivity, user management, and utility functions.

Project Structure

The project follows the modular structure recommended by NestJS, with separate modules for different concerns. Here's an overview of the project structure:
