• ✅ Collaborative Highlights - Highlight text in real-time

• Docker and Docker Compose installed on your system
• At least 4GB of available RAM
• Ports 5000, 5173, and 27017 available

cd SyncScribe

docker-compose up --build

This command will:

• Build the client, server, and MongoDB containers
• Start all services in the correct order
• Wait for MongoDB to be healthy before starting the server

Once all containers are running, open your browser and navigate to:

Client Application: http://localhost:5173

Server API: http://localhost:5000

MongoDB: localhost:27017 (if you need direct database access)

1. Open the application at http://localhost:5173
2. Register a new account by clicking "Register" and providing:
   • Username
   • Email
   • Password
3. Login with your credentials
4. Create your first document by clicking "+ New Document"

docker-compose up -d

docker-compose down

docker-compose down -v

# All services
docker-compose logs -f

# Specific service
docker-compose logs -f server
docker-compose logs -f client
docker-compose logs -f mongo

docker-compose restart server
docker-compose restart client

# Rebuild and restart
docker-compose up --build

# Or rebuild specific service
docker-compose build server
docker-compose up -d server

The application uses the following environment variables (configured in docker-compose.yml):

• MONGO_URL - MongoDB connection string
• MONGO_URI - MongoDB connection string (alias)
• JWT_SECRET - Secret key for JWT tokens (⚠️ Change in production!)
• CLIENT_URL - Frontend URL for CORS

• VITE_API_URL - Backend API URL
• VITE_WS_URL - WebSocket server URL

If you get a port conflict error:

# Check what's using the port
netstat -ano | findstr :5000  # Windows
lsof -i :5000                 # Mac/Linux

# Or change ports in docker-compose.yml

# Check logs
docker-compose logs

# Rebuild from scratch
docker-compose down -v
docker-compose up --build

# Check MongoDB health
docker-compose ps mongo

# Restart MongoDB
docker-compose restart mongo

• Ensure VITE_API_URL and VITE_WS_URL in docker-compose.yml match your setup
• Check that the server container is running: docker-compose ps server
• Check server logs: docker-compose logs server

• Clear browser cache and localStorage
• Open browser console (F12) and check for errors
• Check server logs for DOC_SYNC messages
• Try refreshing the page

cd Server
npm install
# Create .env file with:
# MONGO_URL=mongodb://localhost:27017/realtimenotes
# JWT_SECRET=your_secret
# CLIENT_URL=http://localhost:5173
npm start

cd Client/Client
npm install
# Create .env file with:
# VITE_API_URL=http://localhost:5000/api
# VITE_WS_URL=ws://localhost:5000
npm run dev

⚠️ Important for Production:

1. Change JWT_SECRET in docker-compose.yml to a strong random string
2. Update CORS settings in Server/server.js to allow only your domain
3. Use environment variables for sensitive data (don't hardcode)
4. Enable HTTPS for WebSocket connections (wss://)
5. Set up proper MongoDB authentication
6. Use a reverse proxy (nginx) for production
7. Configure proper logging and monitoring

For issues or questions, check the logs first:

docker-compose logs -f
