📬 Newsletter System – Send & Receive Apps with AWS 🚀

This repository contains two powerful console applications, Send and Receive, that work together to handle messaging efficiently. Built with .NET, AWS, RabbitMQ, and PostgreSQL, this system leverages event-driven architecture to ensure scalable, real-time message processing.

🌟 Key Features

✅ Send & Receive Console Apps – Dedicated applications for sending and processing messages.
✅ AWS Integration – Communicates with AWS services for cloud-based message handling.
✅ RabbitMQ Messaging – Ensures asynchronous, reliable message queuing.
✅ Event-Driven Architecture – Decouples services for better scalability and maintainability.
✅ EF Core + PostgreSQL – Provides efficient and structured data persistence.

🛠 How It Works

1️⃣ The Send Application

• Generates and sends messages to RabbitMQ.
• Stores relevant data in PostgreSQL via EF Core.
• Publishes events for further processing.

2️⃣ The Receive Application

• Listens for messages from RabbitMQ.
• Processes and stores the data in PostgreSQL.
• Ensures fault tolerance and retry mechanisms for reliability.

📂 Technologies Used

🔹 .NET Core – Cross-platform application development.
🔹 AWS – Cloud-based infrastructure support.
🔹 RabbitMQ – Message broker for asynchronous event processing.
🔹 EF Core – ORM for PostgreSQL database interaction.
🔹 PostgreSQL – Reliable and scalable relational database.
🔹 Console Applications – Lightweight, high-performance message handlers.

🚀 Getting Started

Prerequisites

Before running the application, make sure you have:
✅ .NET SDK installed
✅ RabbitMQ running locally or on AWS
✅ PostgreSQL database set up
✅ AWS credentials configured (if needed)

Step 1: Clone the Repository

git clone https://github.com/MrEshboboyev/rabbitmq-dotnet-core
cd newsletter  

Step 2: Configure RabbitMQ & PostgreSQL

• Ensure RabbitMQ is running on localhost:5672 or update the connection string in appsettings.json.
• Create a PostgreSQL database and update the connection string in the project.

Step 3: Run the Applications

Start the Send Application

dotnet run --project src/Send  

Start the Receive Application

dotnet run --project src/Receive

Now, messages sent via SendApp will be processed by ReceiveApp in real-time!

🧪 Testing & Reliability

The system includes:
✅ Retry Mechanisms – Messages are reprocessed in case of failure.
✅ Logging & Monitoring – Tracks messages and failures efficiently.
✅ Database Persistence – Ensures messages are stored and retrieved securely.

---

🔥 Why Use This System?

✅ Asynchronous & Scalable – Handles high message loads efficiently.
✅ Cloud-Ready – Seamless AWS integration for deployment.
✅ Resilient & Fault-Tolerant – Uses RabbitMQ to prevent data loss.
✅ High Performance – Optimized for event-driven architectures.
