# Structure

Each module has well-defined services, controllers, and decorators to handle specific functionalities. The project follows best practices for scalability and performance optimization.

#### Main Components <a href="#main-components" id="main-components"></a>

* **app.module.ts**: The main application module that bootstraps the application.
* **main.ts**: Entry point for the application, responsible for initializing the Nest application.

#### Common <a href="#common" id="common"></a>

* **decorators**: Custom decorators like `dynamic.module.decorator.ts`.
* **interfaces**: Defines contracts for various components, such as `apply-middleware.interface.ts`.
* **middlewares**: Abstract middlewares like `abstract-middleware-loader.ts` for reusable logic.
* **modules**: Contains reusable modules such as `dynamic-modules.ts` and error-handling with `error-handler.filter.ts`.
* **services**: Services that handle dynamic module loading and other common features, e.g., `dynamic-modules-loader.service.ts`.

#### Configuration <a href="#configuration" id="configuration"></a>

* **cache.configuration.ts** and **env.configuration.ts**: Handles cache and environment configurations.
