# Environment Transfer Guide

To transfer the development environment for this application to another PC, you need to install a few key technologies based on the project's configuration (JHipster 9.1.0, Spring Boot monolith).

Here is the complete list of tools and dependencies you need to install on the new PC:

## 1. Required Technologies
*   **Java Development Kit (JDK):** **Version 21** (The project is configured with `sourceCompatibility=21` in `build.gradle`).
*   **Node.js:** **Version >= 24.16.0** (Required for JHipster frontend tooling and code formatting, as specified in `package.json`).
*   **NPM:** Comes bundled with Node.js.
*   **Git:** To clone and transfer your source code.

## 2. Automatically Managed Dependencies (No installation required)
*   **Gradle:** You do **not** need to install Gradle manually. The project uses the Gradle Wrapper (`gradlew`). Running it will automatically download the correct version for you.
*   **Database (Development):** The `dev` profile uses an **H2 in-memory/file-based database**. You do not need to install an external database to run the project locally. 
    *   *(Note: The `prod` profile uses an Oracle Database, which is only necessary if you are running it in production mode).*

## 3. Recommended Tools (Optional)
*   **IDE:** IntelliJ IDEA, Eclipse, or Visual Studio Code with the Java Extension Pack.
*   **Docker Desktop:** Useful if you want to run additional services (like SonarQube or JHipster Control Center) via the `docker-compose` files located in `src/main/docker/`.

## How to start the project on the new PC
Once you've installed **Java 21** and **Node.js >= 24.16.0**, you can transfer your code to the new PC and run the following commands in your project's root folder:

### 1. Install Node dependencies
```bash
npm install
```

### 2. Start the development server
```bash
./gradlew
```
*(On Windows Command Prompt or PowerShell, use `.\gradlew` instead).*

This will download all necessary Java dependencies via Gradle and start the application on `http://localhost:8080`.
