🚀 About the Project Welcome to Eshop, a modern and scalable full-stack e-commerce platform designed using a microservice architecture. This project was built to simulate a real-world production e-commerce system rather than a simple monolithic application. It includes multiple independent services that communicate through APIs and event-driven messaging, along with cloud infrastructure, caching, authentication, payment processing, database management, and asynchronous communication. 🎥 In this video, I showcase the complete Eshop project, its architecture, major features, technologies, and how the different services work together to provide a seamless shopping experience. 🏗️ Architecture The application follows a Microservices Architecture, where different business functionalities are separated into independent services. Each service is responsible for a specific business domain and can be developed, deployed, and scaled independently. 🔹 Microservices The project is divided into multiple services responsible for areas such as: 👤 User / Authentication Service 🛍️ Product Service 🛒 Cart Service 📦 Order Service 💳 Payment Service 📧 Email / Notification Service These services communicate using REST APIs and asynchronous event-driven communication where appropriate. ⚡ Apache Kafka Apache Kafka is used for asynchronous communication and event-driven architecture. Kafka helps services communicate without being tightly coupled. For example: Order Created → Kafka Event → Payment Service → Notification Service This allows the system to process background operations asynchronously and improves scalability and reliability. 🚀 AWS Cloud The project integrates with Amazon Web Services (AWS) for cloud infrastructure and deployment. AWS services are used to build a scalable and production-oriented environment. The project demonstrates concepts such as: ☁️ Cloud deployment 🖥️ Server hosting 📦 Cloud-based infrastructure 🔐 Environment and configuration management 📈 Scalable backend architecture ⚡ Redis Redis is used as an in-memory data store and caching layer. It helps improve application performance by reducing unnecessary database queries and providing fast access to frequently used data. Redis can be used for: 🚀 API response caching ⚡ Fast data access 🛒 Temporary application data 🔄 Session / state-related use cases 📈 Improving overall application performance 💳 Stripe Payment Integration The application integrates Stripe for online payment processing. The payment workflow is designed to securely handle transactions between the customer and the payment system. The project demonstrates: 💳 Online payment integration 🔐 Secure payment processing 🧾 Payment confirmation 📦 Payment and order workflow integration 🗄️ Database & ORM PostgreSQL PostgreSQL is used as the primary relational database for storing application data. The database manages information such as: Users Products Orders Payments Cart information Other application-related data Prisma Prisma ORM is used to interact with PostgreSQL from the backend. It provides type-safe database queries, schema management, migrations, and a clean way to work with relational data. 🔐 Authentication & Security The application includes a secure authentication system with features such as: User registration Login Authentication Authorization Password protection Email verification Protected API endpoints Secure handling of sensitive information 🛒 E-Commerce Features 👤 User Management Registration and login User authentication Email verification User account management 🛍️ Product Management Product listing Product details Product management Database-driven product information 🛒 Shopping Cart Add products to cart Update cart items Remove products Manage cart quantities 📦 Order Management Create orders Track order information Connect orders with payments Manage order workflow 💳 Payment Stripe integration Payment processing Payment confirmation Order-payment integration 📧 Email / Notifications Account-related emails Email verification Order-related notifications Event-driven notification processing 🧰 Technology Stack Frontend React.js JavaScript HTML5 CSS3 Backend Node.js Express.js REST APIs Microservices Architecture Database PostgreSQL Prisma ORM Messaging Apache Kafka Caching Redis Payments Stripe Cloud / Infrastructure AWS Authentication & Security JWT Password hashing Email verification Protected APIs 🔄 Example Order Flow A simplified example of the architecture: Customer ⬇️ Frontend ⬇️ API / Backend Service ⬇️ Order Service ⬇️ PostgreSQL After an order is created: Order Service ⬇️ Kafka Event ⬇️ Payment Service → Stripe And simultaneously: Kafka Event ⬇️ Notification Service ⬇️ Email to Customer Redis can be used as a caching layer to provide faster access to frequently requested data. 🎯 What I Learned From This Project Building Eshop helped me gain practical experience with: Full-stack web development Microservices architecture REST API development Event-driven architecture Apache Kafka Redis caching PostgreSQL database design Prisma ORM Authentication and authorization Stripe payment integration AWS cloud infrastructure Service-to-service communication Asynchronous processing Scalable backend architecture Production-oriented application design This project was a great opportunity to understand how different technologies work together to build a scalable and maintainable real-world e-commerce platform. 📌 Project Highlights 🚀 Full-Stack E-Commerce Platform 🏗️ Microservices Architecture ☁️ AWS Cloud Integration ⚡ Apache Kafka Event Streaming 🔴 Redis Caching 💳 Stripe Payment Gateway 🗄️ PostgreSQL Database 🔧 Prisma ORM 🔐 Authentication & Authorization 📧 Email Verification & Notifications 🔄 REST APIs & Service Communication If you enjoyed the project, don't forget to Like 👍, Comment 💬 and Subscribe 🔔 for more development projects and tutorials. #Eshop #Ecommerce #Microservices #FullStackDevelopment #ReactJS #NodeJS #ExpressJS #PostgreSQL #Prisma #AWS #Kafka #ApacheKafka #Redis #Stripe #JavaScript #RESTAPI #BackendDevelopment #SoftwareDevelopment #WebDevelopment #FullStackDeveloper #CloudComputing
