🚀 Quick Start

1️⃣ Clone & Install Dependencies

# Clone the repository
git clone <repository-url>
cd connectsphere

# Install frontend dependencies
npm install

# Install backend dependencies
cd server
npm install
cd ..

2️⃣ Configure Environment Variables

Frontend - Create .env in project root:

VITE_API_URL=http://localhost:3001/api
VITE_WS_URL=http://localhost:3001
VITE_GOOGLE_CLIENT_ID=your_google_client_id
VITE_APPLE_CLIENT_ID=com.your.bundle.id

Backend - Create server/.env:

PORT=3001
CLIENT_URL=http://localhost:3000
GOOGLE_CLIENT_ID=your_google_client_id_here
APPLE_CLIENT_ID=com.your.bundle.id
ALLOW_MOCK_AUTH=true  # Set to false in production
DATABASE_PATH=./data/connectsphere.db

Development Tip: Set ALLOW_MOCK_AUTH=true to bypass OAuth during development.

3️⃣ Start the Application

Option A: Two Terminal Windows

# Terminal 1 - Backend Server
cd server
npm run dev
# Server runs on http://localhost:3001

# Terminal 2 - Frontend (in new terminal)
npm run dev
# App runs on http://localhost:3000

Option B: One-Command Start (requires concurrently)

npm install -g concurrently
concurrently "cd server && npm run dev" "npm run dev"

4️⃣ Access the Application

• 🌐 Frontend: http://localhost:3000
• 🔧 Backend API: http://localhost:3001/api
• 💚 Health Check: http://localhost:3001/api/health

5️⃣ (Optional) Android Termux Setup

🛡️ Security Best Practices

✅ Built-in Security Features

• ✔️ Helmet.js - Sets secure HTTP headers
• ✔️ Rate Limiting - Prevents API abuse (100 req/15min per IP)
• ✔️ JWT Authentication - Secure session tokens
• ✔️ CORS Protection - Configurable allowed origins
• ✔️ Input Validation - Server-side validation on all inputs
• ✔️ SQL Injection Protection - Parameterized queries only
• ✔️ XSS Protection - Content sanitization
• ✔️ HTTPS Ready - Designed for secure deployment
• ✔️ Teen Safety - Age-appropriate protections and time limits

🔒 Production Security Checklist

Before deploying to production:

• Disable mock authentication (ALLOW_MOCK_AUTH=false)
• Configure proper CORS origins (no wildcards)
• Enable HTTPS/TLS (required for WebRTC)
• Set up TURN servers for NAT traversal
• Configure rate limiting thresholds appropriately
• Implement CSRF protection
• Set secure cookie flags (httpOnly, secure, sameSite)
• Add logging and monitoring (Winston, Sentry)
• Implement input sanitization everywhere
• Set up automated security scanning
• Configure database backups
• Review and update dependencies regularly
• Implement admin dashboard for moderation
• Set up payment processing securely (PCI compliance)

🐛 Troubleshooting

📹 Camera/Microphone Issues

Problem: Camera or microphone not working

Solutions:

• ✅ Ensure you're using HTTPS (or localhost for development)
• ✅ Check browser permissions - grant camera/microphone access
• ✅ Verify devices aren't being used by another application
• ✅ Try a different browser (Chrome recommended)
• ✅ Check device drivers are up to date
• ✅ Test on https://www.webrtc-experiment.com/DetectRTC/

🔌 Connection Issues

Problem: Socket connection failed / Cannot connect to server

Solutions:

• ✅ Verify backend server is running (http://localhost:3001/api/health)
• ✅ Check VITE_WS_URL in frontend .env file
• ✅ Ensure firewall allows port 3001
• ✅ Verify CORS configuration in server/.env
• ✅ Check browser console for specific error messages
• ✅ Try disabling VPN or proxy

🗄️ Database Errors

Problem: Database connection/query failures

Solutions:

• ✅ Ensure server/data/ directory exists (create if missing)
• ✅ Check file permissions on database file
• ✅ Verify SQLite is properly installed
• ✅ Try deleting database file to reset: rm server/data/connectsphere.db ⚠️ (data loss)
• ✅ Check database path in server/.env

🔨 Build Errors

Problem: Build fails or dependencies won't install

Solutions:

• ✅ Clear node_modules: rm -rf node_modules package-lock.json && npm install
• ✅ Verify Node.js version: node --version (must be 18+)
• ✅ Check all environment variables are set correctly
• ✅ Look for port conflicts: lsof -i :3000 or lsof -i :3001
• ✅ Try cleaning Vite cache: rm -rf node_modules/.vite
• ✅ Update npm: npm install -g npm@latest

🔐 Authentication Problems

Problem: Login fails or auth errors

Solutions:

• ✅ Verify Google/Apple OAuth credentials are correct
• ✅ Check OAuth redirect URIs match your domain exactly
• ✅ Ensure ALLOW_MOCK_AUTH=true is set for development without OAuth
• ✅ Check browser console and network tab for detailed errors
• ✅ Verify JWT token is being sent in requests
• ✅ Clear browser cookies and local storage

⚡ Performance Issues

Problem: Slow performance or high latency

Solutions:

• ✅ Enable Bandwidth Saver Mode
• ✅ Lower video quality in Connection Quality settings
• ✅ Run Network Diagnostics to test your connection
• ✅ Close unnecessary browser tabs and applications
• ✅ Check CPU usage - video processing is intensive
• ✅ Ensure adequate internet bandwidth (min 1 Mbps recommended)

📐 Code Standards

TypeScript Best Practices:

// ✅ Good: Properly typed function
const calculateStats = (userId: string): UserStats => {
  // Implementation
};

// ❌ Bad: Using 'any' type
const calculateStats = (userId: any): any => {
  // Implementation
};

React Best Practices:

• ✅ Use functional components with hooks
• ✅ Keep components small and focused (< 200 lines)
• ✅ Extract reusable logic into custom hooks
• ✅ Use meaningful component and variable names
• ✅ Implement proper error boundaries
• ✅ Memoize expensive computations with useMemo
• ✅ Use useCallback for callback props

Component Structure:

// ✅ Good structure
import React, { useState, useEffect } from 'react';
import { SomeType } from '../types';

interface MyComponentProps {
  userId: string;
  onClose: () => void;
}

export const MyComponent: React.FC<MyComponentProps> = ({ userId, onClose }) => {
  // Hooks at the top
  const [data, setData] = useState<SomeType | null>(null);
  
  // Effects
  useEffect(() => {
    // Effect logic
  }, [userId]);
  
  // Event handlers
  const handleClick = () => {
    // Handler logic
  };
  
  // Render
  return (
    <div className="component-container">
      {/* JSX */}
    </div>
  );
};
