### 3. Error Handling

**Pattern:**
```javascript
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:**
```html
<div class="inline-message inline-error" data-error-message>
  ⚠️ Failed to load data. Retrying...
</div>
```

### 4. Real-time Updates (WebSocket)

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

### 5. Loading States

**Before:**
```html
<tbody data-top-coins-body></tbody>
```

**After:**
```html
<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:**
```javascript
// 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:**
```javascript
// Relative: "2 hours ago"
formatRelativeTime(timestamp)

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

### 7. Sentiment Display

**Badge Colors:**
```css
.sentiment-bullish { 
  background: var(--success); 
  color: white;
}

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

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

**Usage:**
```html
<span class="chip sentiment-bullish">
  Bullish (87%)
</span>
```

### 8. Settings Persistence

**LocalStorage:**
```javascript
// Save
localStorage.setItem('theme', 'dark');
localStorage.setItem('marketInterval', '30');

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

## 📦 Files که با admin.html کار می‌کنند

### Required JS Files (همه باید ES6 modules باشند):

1. **static/js/app.js**
   - Main application entry
   - Navigation handling
   - View initialization

2. **static/js/apiClient.js**
   - HTTP request wrapper
   - Caching
   - Error handling

3. **static/js/wsClient.js**
   - WebSocket management
   - Reconnection logic
   - Event broadcasting

4. **static/js/*View.js**
   - overviewView.js
   - marketView.js
   - chartLabView.js
   - aiAdvisorView.js
   - newsView.js
   - providersView.js
   - datasetsModelsView.js
   - apiExplorerView.js
   - debugConsoleView.js
   - settingsView.js

### Required CSS Files:

1. **static/css/design-tokens.css** - Color, spacing, typography tokens
2. **static/css/design-system.css** - Components (buttons, cards, forms)

4. **static/css/pro-dashboard.css** - Advanced styling

## 🚀 Quick Start

### 1. Ensure Backend is Running
```bash
uvicorn hf_unified_server:app --host 0.0.0.0 --port 7860
```

### 2. Access Dashboard
```
http://localhost:7860/
```

### 3. Check Browser Console
```javascript
// 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
```bash
curl http://localhost:7860/api/health
```

### Issue: WebSocket shows "error"
**Solution:** Check WebSocket endpoint
```bash
# In browser console:
const ws = new WebSocket('ws://localhost:7860/ws');
ws.onopen = () => console.log('Connected');
```

### Issue: Empty tables
**Solution:** Check API responses
```bash
curl http://localhost:7860/api/coins/top?limit=10
curl http://localhost:7860/api/market/stats
```

### Issue: Sentiment always "neutral"
**Solution:** Check models initialized
```bash
curl http://localhost:7860/api/models/list
```
