A microservices-based application for a modern e-commerce platform. This repository contains the backend services built with Java and Spring Boot, structured as a monorepo.
The system is composed of two main services:
- E-commerce Service: Handles core business logic like product management, user authentication, shopping cart, and order processing.
- Notification Service: A dedicated service for sending notifications (like email or SMS) to users in response to events within the platform.
To enhance the scalability and responsiveness of the application, several optimization techniques have been integrated:
- Pagination: Efficiently handles large datasets in APIs by limiting the number of records returned per request.
- Indexing: Database indexing applied to frequently queried fields to speed up data retrieval.
- Redis Cache: Implements caching layer using Redis to reduce database load and improve response times for commonly accessed data.
- 👤 User Authentication & Authorization: Secure user registration and login using Spring Security.
- 📦 Product Catalog: Functionality to add, update, view, and delete products.
- 🛒 Shopping Cart: Manage items in a user's cart.
- 💳 Order Management: End-to-end order placement and tracking workflow.
- 📢 Event-Driven: Publishes events (e.g.,
ORDER_PLACED) to a Kafka topic.
- 📧 Email Notifications: Consumes events from Kafka to send timely emails.
- 📄 Templated Messages: Uses templates for different notification types (e.g., Order Confirmation, Shipping Update).
- 🔄 Decoupled Architecture: Operates independently of the main E-commerce service, ensuring reliability.
- Backend: Java 17, Spring Boot 3
- Data: Spring Data JPA, Hibernate, MySQL
- Messaging Queue: Apache Kafka
- Security: Spring Security
- Build Tool: Maven
- (Frontend): React
