🧭 Features
Modular microservices architecture – each service runs independently
Authentication & Authorization using JWT tokens via AuthAPI
Cart, Coupon, Order workflows with message-driven integration
Payment processing and email service for real order workflow
Interactive MVC UI connecting to gateway & APIs

🧪 **Getting Started
Prerequisites**
.NET 6 SDK or higher installed
Visual Studio 2022 / VS Code
Docker (for RabbitMQ and optional Mongo/SQL containers)
Connection strings configured in each service appsettings.json
Setup Steps Clone the repo
bash Copy Edit git clone https://github.com/Vanshika0901/ShopShere cd Mango_Microservices Run RabbitMQ via Docker (if not using Azure Service Bus)
bash Copy Edit Open Mango.sln in Visual Studio or via CLI
Run each service project individually
Launch MVC UI (Mango.Web)
This will host the storefront, allowing you to browse products, create account, add to cart, checkout, etc.
API Gateway (Mango.GatewaySolution) should be configured to route to each service endpoint and apply authentication logic.
🧠 API Usage (via API Gateway)
POST /api/auth/login → Get JWT token
GET /api/products → List of products (public)
POST /api/cart → Add item (authenticated user)
POST /api/order → Checkout cart
POST /api/payment → Process payment
POST /api/email/send → Send confirmation email
Note: Actual paths may differ by service. Please check each service's appsettings.json or swagger docs.
