OrderAPI

OrderAPI is an API developed for handling order operations. The project supports functionalities such as product listing, order creation, and asynchronous email sending via RabbitMQ.

Technologies

• Framework: .NET 6
• Language: C#
• Database: MySQL
• ORM: Entity Framework (Code First)
• Memory Cache: Redis
• Message Queue: RabbitMQ
• Tools: AutoMapper, Serilog

Workflow

1. Product Listing: The API provides a GET method to list products. It first checks Redis cache; if not found, it fetches the data from the database and caches it.
2. Order Creation: An order is created via a POST method. Order details are saved in the database, and an email sending request is added to the RabbitMQ queue.
3. Email Sending: Email requests in the RabbitMQ queue are processed by a background service.

Project Structure

The project follows the Onion Architecture:

• Domain: Entity classes
• Application: Business logic, service interfaces and DTOs
• Infrastructure: RabbitMQ services, background services and other infrastructure components
• Persistence: Handles all database operations
• WebAPI: Hosts the API endpoints

RabbitMQ Usage

• PublishToQueue: Sends messages to the specified queue
• Consume: Listens to the specified queue and processes incoming messages

Setup

Requirements

• .NET SDK 6+
• Docker (for Redis)
• MySQL

Run the Project

1. Clone the repository:

   git clone https://github.com/huseyinerdin/OrderAPI.git
   cd OrderAPI

2. Restore dependencies:

   dotnet restore

3. Set up Redis using Docker

   docker run -d --name my-redis -p 6379:6379 redis

4. Configuration : Edit appsettings.json with your RabbitMQ, MySQL, and Redis connection settings:

   "ConnectionStrings": {
           "MySqlConnection": "server=localhost;port=3306;database=OrderDb;user=your_username;password=your_password;"
       },
   "RabbitMq": {
           "HostName": "localhost",
           "Port": "5672",
           "UserName": "guest",
           "Password": "guest"
       },
   "Redis": {
           "ConnectionString": "localhost:6379"
       }

5. Run the application:

   dotnet run
