The Order Service is a backend service responsible for handling order management in an e-commerce application. This service allows for creating orders, retrieving order details, and processing orders through integration with other services like Product and User services.

• Create new orders with product and user details.
• Retrieve all orders.
• Retrieve orders by user ID.
• Integration with RabbitMQ for message queuing.
• RESTful API architecture.

• Node.js
• Express.js
• Sequelize (ORM)
• PostgreSQL (Database)
• Axios (HTTP Client)
• RabbitMQ (Message Broker)

To set up the Order Service locally, follow these steps:

1. Clone the repository:

   git clone https://github.com/yourusername/order-service.git
   cd order-service

2. Install dependencies:

   npm install

3. Set up your environment variables: Create a .env file in the root directory and add your database and RabbitMQ configurations.

   DB_HOST=localhost
   DB_USER=your_db_user
   DB_PASSWORD=your_db_password
   DB_NAME=your_db_name
   RABBITMQ_URL=amqp://localhost

4. Run database migrations:

   npx sequelize-cli db:migrate

5. Start the service:

   npm start

Once the service is running, you can interact with the API at http://localhost:3000. Use tools like Postman or cURL to test the endpoints.
