✅ JWT Authentication - 7-day tokens ✅ Password Hashing - Bcryptjs (10 rounds) ✅ Input Validation - All fields validated ✅ CORS Protection - Cross-origin configured ✅ Helmet Headers - Security headers enabled ✅ NoSQL Prevention - Injection attacks prevented ✅ Admin Control - Role-based access ✅ Error Handling - No info leaks

# Login
curl -X POST http://localhost:5000/api/users/login \
-H "Content-Type: application/json" \
-d '{"email":"admin@gcu.edu.pk","password":"Admin@123456"}'
# You'll get a response with a token- Create new request
- Method: POST
- URL: http://localhost:5000/api/users/login
- Body (JSON):
{"email":"admin@gcu.edu.pk","password":"Admin@123456"} - Send
- Save the token from response
Same as Postman but in VS Code
Your React app needs to:
-
Update API URL:
const API_URL = "http://localhost:5000/api";
-
Implement Login:
POST / api / users / login; Body: { email, password; } Response: { token, user; }
-
Store Token:
localStorage.setItem("token", responseToken);
-
Add to Requests:
headers: { 'Authorization': `Bearer ${token}` }
See API_DOCUMENTATION.md for full details!
PORT=5000
NODE_ENV=development
MONGODB_URI=mongodb://localhost:27017/css-society
JWT_SECRET=your_secret_key_here
JWT_EXPIRE=7d
ADMIN_EMAIL=admin@gcu.edu.pk
ADMIN_PASSWORD=Admin@123456
CORS_ORIGIN=http://localhost:5173
For Production:
- Change JWT_SECRET to random string
- Change admin password
- Use MongoDB Atlas for MONGODB_URI
- Set NODE_ENV=production
# Start server
npm start
# Install dependencies
npm install
# Stop server
Ctrl + C
# Check if running
curl http://localhost:5000/api/health- Ensure MongoDB is running
- Check MONGODB_URI in .env
- For local:
mongodb://localhost:27017/css-society
- Change PORT in .env (e.g., 5001)
- Or kill process:
netstat -ano | findstr :5000
- Login again to get new token
- Check Authorization header:
Bearer TOKEN - Tokens expire after 7 days
- Check console output for errors
- Ensure MongoDB is running
- Delete existing admin if needed
- ✅ Install MongoDB (if not done)
- ✅ Run
npm startin server folder - ✅ Test login endpoint
- ✅ Verify API works
- ✅ Connect React frontend
- ✅ Implement login flow
- ✅ Test all endpoints
- ✅ Verify features work
- ✅ Deploy to production
- ✅ Change admin credentials
- ✅ Use MongoDB Atlas
- ✅ Enable HTTPS

- Start with QUICK_START.md - Fastest way to get running
- Use Postman - Great for API testing
- Keep .env secure - Never commit to git!
- Check console logs - Errors help debugging
- Read the code - Comments explain everything
- Start with login - Test authentication first
Before you think you're done, verify:
Server Setup
├─ ✅ npm install completed
├─ ✅ npm start runs without errors
└─ ✅ Can access http://localhost:5000/api/health
Database
├─ ✅ MongoDB is running
├─ ✅ Can see "MongoDB connected" in logs
└─ ✅ Admin user was created
API Testing
├─ ✅ Can login with admin credentials
├─ ✅ Receive token in response
├─ ✅ Can access protected endpoints
└─ ✅ Can create events/announcements
Frontend Integration
├─ ✅ Frontend can connect to backend
