Architecture

The application is built using a microservices architecture with the following services:

Microservices

1. Catalog Microservice: Manages the catalog of items.
2. Cart Microservice: Manages the shopping cart.
3. Identity Microservice: Manages authentication and user information.

Each microservice has its own dedicated database, following the database-per-service pattern. This ensures better separation of concerns, scalability, and data isolation. Key advantages include:

• Independent schema updates.
• Prevents unauthorized cross-service data access.
• Independent scaling of services.
• Ability to use different database technologies per service.

API Gateways

• Frontend API Gateway: Handles client-side requests.
• Backend API Gateway: Handles admin-side requests.

Frontend API Gateway Endpoints

• GET /catalog: Retrieves catalog items.
• GET /catalog/{id}: Retrieves a specific catalog item.
• GET /cart: Retrieves cart items.
• POST /cart: Adds an item to the cart.
• PUT /cart: Updates a cart item.
• DELETE /cart: Deletes a cart item.
• POST /identity/login: Logs in a user.
• POST /identity/register: Registers a new user.
• GET /identity/validate: Validates a JWT token.

Backend API Gateway Endpoints

• GET /catalog: Retrieves catalog items.
• GET /catalog/{id}: Retrieves a specific catalog item.
• POST /catalog: Creates a catalog item.
• PUT /catalog: Updates a catalog item.
• DELETE /catalog/{id}: Deletes a catalog item.
• PUT /cart/update-catalog-item: Updates catalog items in carts.
• DELETE /cart/delete-catalog-item: Deletes catalog item references from carts.
• POST /identity/login: Logs in a user.
• GET /identity/validate: Validates a JWT token.
