KafeinTech E-Commerce Case

This project is a microservice-based e-commerce application built using .NET 8.

The project consists of four main microservices: Order, Identity, Invoices, and Mails.

Each microservice operates independently and communicates via MassTransit.

Microservices

Order Microservice

• Tables: Product, Order, OrderItem
• Initial Data: Five sample products
• Functions: Creating products and handling orders
• Communication: Order info and invoice info queues

Identity Microservice

• Functions: Generating JWT tokens
• Endpoint: Login

Invoices Microservice

• Functions: Creating invoices and sending emails
• Communication: Invoice info queues

Mails Microservice

• Functions: Sending emails
• Communication: Email info queues

Setup and Execution

1. Navigate to each microservice directory and start it using dotnet run.
2. Send dummy user credentials to the Identity Microservice's Login endpoint to get a token.
3. Use the token to send productId and quantity to the Order Microservice's CreateOrder endpoint.
4. Communication between microservices will be handled by MassTransit, and relevant processes will be executed automatically.
