3. Error Handling

Pattern:

try {
  const response = await apiClient.get('/api/coins/top');
  if (response.ok && response.data) {
    // Success handling
    updateUI(response.data);
  } else {
    // Error handling
    showError(response.error || 'Request failed');
  }
} catch (error) {
  // Network error
  showError('Network error: ' + error.message);
}

User Feedback:

<div class="inline-message inline-error" data-error-message>
  ⚠️ Failed to load data. Retrying...
</div>

4. Real-time Updates (WebSocket)

Connection:

// wsClient.js connects to /ws
wsClient.connect();

wsClient.subscribe('update', (data) => {
  // Update UI with:
  // - Market data
  // - Sentiment scores
  // - News headlines
  updateDashboard(data.payload);
});

Update Frequency: Every 10 seconds

Data Structure:

{
  "type": "update",
  "payload": {
    "market_data": [...],
    "stats": {...},
    "news": [...],
    "sentiment": {
      "label": "bullish",
      "confidence": 0.75
    },
    "timestamp": "2024-11-18T02:00:00Z"
  }
}

5. Loading States

Before:

<tbody data-top-coins-body></tbody>

After:

<tbody data-top-coins-body>
  <tr>
    <td colspan="7" style="text-align:center;padding:2rem;">
      Loading top coins...
    </td>
  </tr>
</tbody>

6. Responsive Data Formatting

Numbers:

// Price: $65,432.10
price.toLocaleString('en-US', {
  style: 'currency',
  currency: 'USD'
})

// Percentage: +5.23%
change.toFixed(2) + '%'

// Large numbers: 1.2B
formatLargeNumber(1234567890) // → '1.23B'

Dates:

// Relative: "2 hours ago"
formatRelativeTime(timestamp)

// Absolute: "Nov 18, 2024 2:30 PM"
new Date(timestamp).toLocaleString()

7. Sentiment Display

Badge Colors:

.sentiment-bullish { 
  background: var(--success); 
  color: white;
}

.sentiment-bearish { 
  background: var(--error); 
  color: white;
}

.sentiment-neutral { 
  background: var(--warning); 
  color: black;
}

Usage:

<span class="chip sentiment-bullish">
  Bullish (87%)
</span>

8. Settings Persistence

LocalStorage:

// Save
localStorage.setItem('theme', 'dark');
localStorage.setItem('marketInterval', '30');

// Load on startup
const theme = localStorage.getItem('theme') || 'dark';
const interval = localStorage.getItem('marketInterval') || '30';

Required JS Files (همه باید ES6 modules باشند):

static/js/app.js
- Main application entry
- Navigation handling
- View initialization
static/js/apiClient.js
- HTTP request wrapper
- Caching
- Error handling
static/js/wsClient.js
- WebSocket management
- Reconnection logic
- Event broadcasting
*static/js/View.js
- overviewView.js
- marketView.js
- chartLabView.js
- aiAdvisorView.js
- newsView.js
- providersView.js

static/css/design-system.css - Components (buttons, cards, forms)
static/css/dashboard.css - Dashboard layout
static/css/pro-dashboard.css - Advanced styling

🚀 Quick Start

1. Ensure Backend is Running

uvicorn hf_unified_server:app --host 0.0.0.0 --port 7860

2. Access Dashboard

http://localhost:7860/

3. Check Browser Console

// Should see:
✓ API Client initialized
✓ WebSocket connected
✓ Market data loaded
✓ Sentiment models ready

✅ Testing Checklist

Overview page loads stats
Top 10 coins displayed
Sentiment chart shows data
WebSocket badge shows "connected"
Market page shows 50 coins
Click coin → Detail drawer opens
Chart Lab displays price chart
AI Analysis returns results
Sentiment analysis works
News page shows headlines with sentiment
Providers listed (95+)
Datasets listed (14+)
Models listed (10+)
Model test returns results
API Explorer shows endpoints
Diagnostics shows health status
Settings save/load from localStorage

🐛 Troubleshooting

Issue: "checking" status never changes

Solution: Backend /api/health endpoint not responding

curl http://localhost:7860/api/health

Issue: WebSocket shows "error"

Solution: Check WebSocket endpoint

# In browser console:
const ws = new WebSocket('ws://localhost:7860/ws');
ws.onopen = () => console.log('Connected');

Issue: Empty tables

Solution: Check API responses

curl http://localhost:7860/api/coins/top?limit=10
curl http://localhost:7860/api/market/stats

Issue: Sentiment always "neutral"

Solution: Check models initialized

curl http://localhost:7860/api/models/list
