-# Base-REST-API
-
-A robust, modular, and secure REST API boilerplate built with **Node.js** and **Express**.
-It features a **recursive file loader** for routes and schemas, along with a powerful validation middleware using **Zod**.
-
-## 🚀 Features
-
-- **Automated Loading**: Recursively loads routes and validation schemas from the file system.
-- **Strict Validation**: Request bodies and query parameters are validated using [Zod](https://zod.dev/) before reaching the controller.
-- **Clean Architecture**: Separation of concerns with `Routes` (HTTP layer), `Services` (Business logic), and `Schemas` (Validation).
-- **Security First**: Inputs are stripped of unknown fields automatically.
-- **Custom Logger**: Integrated color-coded logging system for development and file logging for production.
-- **Error Handling**: Standardized JSON error responses.
-
-## 📦 Installation
-
-1. **Clone the repository**
-   ```bash
-      git clone https://gitea.azures.fr/azures04/Base-REST-API.git
-      cd Base-REST-API
-   ```
