Eco-Dex: E-commerce Microservices Platform

Overview

Eco-Dex is a modern, scalable e-commerce platform built using a microservices architecture. The platform provides a robust foundation for building and deploying e-commerce applications with features like user management, product catalog, shopping cart, order processing, payment integration, and real-time notifications.

System Design

High-Level Architecture

• Microservices-based architecture for modularity and scalability
• Event-driven communication using Apache Kafka
• Distributed caching with Redis
• Load balancing and API Gateway using Nginx
• Container orchestration with Kubernetes

Scalability Considerations

• Horizontal scaling of services based on load
• Database sharding and replication
• Caching strategies at multiple levels
• Message queue for asynchronous processing
• CDN integration for static assets

Security Measures

• JWT-based authentication
• Role-based access control (RBAC)
• API rate limiting
• Data encryption at rest and in transit
• Regular security audits and penetration testing

Architecture

The platform consists of the following microservices:

• User Service (Port 3001): Handles user authentication, authorization, and profile management
• Product Service (Port 3002): Manages product catalog, inventory, and search functionality
• Cart Service (Port 3003): Manages shopping cart operations with Redis-based caching
• Order Service (Port 3004): Processes orders and manages order lifecycle
• Payment Service (Port 3005): Handles payment processing and transaction management
• Notification Service (Port 3006): Manages real-time notifications and alerts

Tech Stack

• Backend: Node.js microservices
• Database: PostgreSQL
• Caching: Redis
• Message Broker: Apache Kafka
• API Gateway: Nginx
• Containerization: Docker
• Container Orchestration: Kubernetes
• Infrastructure as Code: Terraform
• Monitoring: Prometheus, Grafana, ELK Stack

Advanced Features

Search and Filtering

• Elasticsearch integration for product search
• Advanced filtering and faceted search
• Search suggestions and autocomplete

Performance Optimization

• Image optimization and lazy loading
• Database query optimization
• Response caching
• Minification and bundling of assets

Analytics and Reporting

• Real-time analytics dashboard
• Sales and inventory reports
• User behavior tracking
• Performance metrics monitoring

Getting Started

Prerequisites

• Docker and Docker Compose
• Node.js (v14 or higher)
• Make (for using Makefile commands)

Local Development Setup

1. Clone the repository:

   git clone https://github.com/rowjay007/eco-dex.git
   cd eco-dex

2. Set up the development environment:

   make dev-setup

3. Install dependencies for all services:

   make build

4. Start the services using Docker Compose:

   make docker-up

5. Access the services:

   • API Gateway: http://localhost:8080
   • Individual service endpoints are available at their respective ports

Environment Variables

The platform uses a centralized .env file for base configuration, with service-specific .env files for individual service configuration. Key environment variables include:

• NODE_ENV: Application environment
• DB_*: Database configuration
• REDIS_*: Redis configuration
• KAFKA_*: Kafka configuration
• Service-specific ports and configurations
