    • Event handlers
    • Error handling
    • Data formatting utilities

Backend Integration

Modified cmd/trading/main.go:

  • Added static file server for frontend directory
  • Maintained all existing API endpoints
  • Proper routing order (API routes before static files)

Configuration Updates

  1. README.md

    • Added "Web Dashboard" section
    • Updated Quick Start guide
    • Updated project structure
    • Added frontend feature to features list

  2. .gitignore

    • Added node_modules exclusion

    • Future-proofed for potential npm dependencies

API Endpoints Used

The frontend consumes the following API endpoints:

  • GET /api/health - Health check and server status
  • GET /api/status - Overall trading status and metrics summary
  • GET /api/candidates - List of token candidates
  • GET /api/metrics - Detailed metrics
  • GET /api/risk - Risk management status
  • POST /api/risk/resume - Resume trading after halt

Testing Results

Functional Testing

✅ Server starts successfully and serves frontend ✅ All API endpoints respond correctly ✅ Frontend loads without errors ✅ Real-time data updates working ✅ Auto-refresh functioning (5-second interval) ✅ Manual refresh button working ✅ Responsive design verified ✅ Connection status indicator working

Security Testing

✅ CodeQL analysis: 0 alerts (Go and JavaScript) ✅ No sensitive data exposure ✅ CORS properly configured ✅ No XSS vulnerabilities ✅ No injection risks

Browser Compatibility

✅ Modern browsers (Chrome, Firefox, Edge, Safari) ✅ Mobile responsive design ✅ No external dependencies required

User Experience

Access

  1. Start the trading bot: make build && ./bin/trading
  2. Open browser to: http://localhost:8080
  3. Dashboard loads automatically with real-time data

Key Benefits

  • Zero Configuration: Works out of the box
  • Real-time Updates: See changes as they happen
  • No Dependencies: Pure HTML/CSS/JS
  • Mobile Friendly: Works on all devices
  • Clean UI: Professional, modern design
  • Easy Control: Resume trading with one click

Code Quality

JavaScript
