Quick setup

1. Install dependencies: npm install

2. Create a .env in project root (example): PORT=3000 DB_HOST=localhost DB_USER=root DB_PASS=password DB_NAME=service_catalog DB_DIALECT=mysql JWT_SECRET=your_jwt_secret

3. Start the app: npm run dev or use a process manager / nodemon in development.

The app will authenticate with the DB and call sequelize.sync() on startup.
