📰 Blog Platform – Microservices Architecture

A full-stack, scalable Blog Platform built with React.js, Node.js, and Microservices Architecture. The system separates read and write operations, applies strict security and rate-limiting, and is designed to scale efficiently for real-world blogging needs.

🧱 Architecture Overview

This system follows the Microservices pattern to separate responsibilities across three main services:

1. 🌀 API Gateway

• Acts as the entry point to all backend services
• Handles authentication, rate limiting, request routing, and logging
• Protects services with middleware like helmet, cors, express-rate-limit, and Redis-backed rate limiting

2. 📝 Post Management Service (Write Layer)

• Handles all authenticated user interactions:
  • Create, edit, delete posts
  • Like/unlike
  • Commenting
• Uses:
  • MongoDB via Mongoose
  • JWT for token-based auth
  • Cloudinary for image storage
  • RabbitMQ for event messaging (via amqplib)
  • Joi for request validation

3. 📚 Post Public Service (Read Layer)

• Serves all non-authenticated features:
  • View latest posts
  • Search by tags, title, slug
  • Fetch post details
• Reduces load on the write server
• Optimized for high read scalability

🎨 Frontend – React.js

Key Highlights:

• Built with modern React (react-router-dom, axios, etc.)
• Optimized Rendering: Low re-renders with memo, lazy, Suspense
• Animations: Smooth transitions using Framer Motion (or similar)
• Responsive Design: TailwindCSS / custom styling
• Error Handling: Toast notifications and fallback UIs
• JWT Integration: Full auth token flow using interceptors

📦 Tech Stack

Layer	Tech Used
Frontend	React.js, Axios, TailwindCSS, Framer Motion
API Gateway	Node.js, Express, Helmet, Redis, JWT
Post Management	Node.js, Express, MongoDB, RabbitMQ, Joi
Post Public	Node.js, Express, MongoDB (Read Optimized)
Auth	JWT, Bcrypt, User service (separate)

🔐 Security & Performance

• Redis + express-rate-limit for DDoS protection
• Helmet for securing HTTP headers
• API-level token authentication
• Microservice isolation to ensure high availability
