E-Commerce Application

Overview

This is a full-stack e-commerce application based on a microservice architecture. It implements an event-driven approach for handling user interactions, leveraging event sourcing. The backend includes microservices (CustomerService, ProductService) that communicate via REST APIs. User interactions are captured as events and persisted to a kafka topic that meant to be fiched by the pageEventService and petsit to mongo database .

Backend Microservices

Each microservice is developed with Spring Boot and offers a RESTful API. They utilize Spring Data MongoDB for data persistence and Spring Cloud Stream Functions for event-driven communication.
