🚀 Getting Started

📋 Prerequisites

• MySQL Server (optional, fallback H2 requires zero setup).

---

⚙️ Database Configuration Setup

By default, the application is pre-configured to run with a local MySQL database. All configuration properties are managed in [src/main/resources/application.properties].

Option A: Running with MySQL (Default)

1. Ensure your local MySQL server is running.
2. The app will automatically try to connect to:
   • URL: jdbc:mysql://localhost:3306/onlinebookstore (it will auto-create the database if it doesn't exist).
   • Username: root
   • Password: My_sql_WorkBench_root_Password
3. If your MySQL credentials are different, you can customize them easily using a .env file (see the Environment Variables section below).

Option B: Running with H2 In-Memory DB (Zero-Setup)

If you do not have MySQL installed, you can switch to a lightweight In-Memory database:

1. Open [application.properties].
2. Comment out the MySQL Configuration section (lines 5–9).
3. Uncomment the H2 Memory DB Configs section (lines 20–25).
4. Run the project!

🔑 Environment Variables

This project supports standard environment overrides for sensitive credentials. You can create a file named .env in the project root folder based on the provided [.env.example]:

# Server Port
PORT=8081

# Database Credentials
DB_URL=jdbc:mysql://localhost:3306/onlinebookstore?createDatabaseIfNotExist=true&useSSL=false&allowPublicKeyRetrieval=true
DB_USERNAME=your_username
DB_PASSWORD=your_password

---
