Waitlist Management System

A real-time restaurant waitlist management application with Django backend and React frontend.

System Components

Backend

• Django Server: Main application backend running on port 8000
• Socket.IO Server: Real-time notification server running on port 3000

Frontend

• React Application: User interface running on port 3001

Socket.IO Server Management

The Socket.IO server is essential for real-time updates. Several tools are available to manage it:

Socket.IO Server Manager

# Check server status
node socket_server_manager.js status

# Start the server
node socket_server_manager.js start

# Stop the server
node socket_server_manager.js stop

# Restart the server
node socket_server_manager.js restart

Health Check

To quickly check if the Socket.IO server is running properly:

node check_socketio.js

Setup and Running the Application

Backend Setup

1. Set up Python virtual environment:

   cd backend
   python -m venv .venv
   source .venv/bin/activate  # On Windows: .venv\Scripts\activate
   pip install -r requirements.txt

2. Run Django migrations:

   python manage.py migrate

3. Start Django server:

   python manage.py runserver

4. Start Socket.IO server:

   node socket_server_manager.js start

Frontend Setup

1. Install dependencies:

   cd frontend
   npm install

2. Start development server:

   npm start

Troubleshooting

If you experience issues with real-time updates:

1. Check Socket.IO server status:

   node socket_server_manager.js status

2. Ensure the Django backend is configured correctly to communicate with the Socket.IO server.

3. Verify the frontend is connecting properly to the Socket.IO server using the browser's developer console.
