📝 Blog Platform (React + Express + Redis + Node + MongoDB)

This project is a full-stack blogging platform that includes autosaving with Redis, secure JWT-based authentication, drafts, and support for editing published posts. Built with Vite + React on the frontend and Express.js on the backend.

🔋 Features

• ⚡ React + Vite frontend with JoditEditor for rich text editing
• 🔐 Secure JWT Authentication (stored in HTTP-only cookies)
• 💾 Autosaving using Redis (5s idle or 45s interval)
• 📝 Draft system to resume unfinished posts
• ✏️ Edit already published posts
• 📦 MongoDB for persistent post storage
• 🔁 Redis for temporary autosave caching
• 🔄 REST API with full CRUD for blog posts

🚀 Getting Started

1. Clone the Repository

git clone https://github.com/your-username/blog-platform.git
cd blog-platform

---

2. Backend Setup (server/)

cd server
npm install

Create .env file

PORT=3000
MONGO_URI=your_mongodb_connection_string
JWT_SECRET=your_jwt_secret
REDIS_URL=redis://localhost:6379
CLIENT_URL=http://localhost:5173

Start the server

npm run dev

---

3. Frontend Setup (client/)

cd client
npm install
npm run dev

React app runs on http://localhost:5173

---

🔐 Authentication with JWT

• JWT tokens are issued upon login and stored as HTTP-only cookies.
• Tokens are automatically sent with every request using Axios.

axios.post('http://localhost:3000/autoSave', postData, {
  withCredentials: true
});

---

💾 Autosaving via Redis

• Triggers on:
  • 5 seconds of typing inactivity
  • Every 45 seconds regardless
• Only active when the post is unsaved (not in draft/published state)

Redis Key Format

autosave:<userId>

Example Redis commands

redis-cli
keys *
get autosave:123

🧠 Redis Key Usage

autosave:<userId>

Used to store in-progress post content per user.

---

✅ Workflow Summary

1. User logs in via /login (JWT token issued in cookie)
2. Starts a new post or resumes a draft
3. Autosave kicks in every 5s idle or 45s interval
4. On draft/save:
   • MongoDB stores the post
   • Redis autosave key is cleared
5. User can edit drafts or published posts

---

✨ Development Tips

• Use Postman to test endpoints
• Use redis-cli to check autosave entries
• Add middleware to validate JWT in protected routes

---

🛠️ Linting and Formatting
