| # 📊 گزارش جامع تحلیل معماری دریافت داده | |
| ## Dreammaker Crypto Platform - Data Architecture Analysis | |
| **تاریخ تهیه:** 5 دسامبر 2025 | |
| **نسخه:** 1.0 | |
| **وضعیت:** تحلیل کامل و پیشنهادات بهبود | |
| --- | |
| ## 🎯 خلاصه اجرایی | |
| ### مشکل اصلی | |
| پروژه فعلی دارای **معماری پراکنده و غیرمتمرکز** برای دریافت داده است. درخواستهای API در **بیش از 60 فایل مختلف** پخش شدهاند و هیچ **شاهراه مشخصی (Highway)** برای عبور دادهها وجود ندارد. | |
| ### نقاط ضعف کلیدی | |
| 1. ❌ **نبود لایه واحد دریافت داده** - Data Fetching Layer | |
| 2. ❌ **تکرار کد** - هر کامپوننت به تنهایی با API ارتباط میگیرد | |
| 3. ❌ **مدیریت ضعیف Hugging Face Hub** - درخواستهای نامنظم و غیرکنترلشده | |
| 4. ❌ **عدم وجود Cache Strategy مشخص** | |
| 5. ❌ **ناسازگاری در Error Handling** | |
| 6. ❌ **نبود Retry Logic یکسان** | |

| ## 🔍 بخش 2: تحلیل عمیق Hugging Face Integration | |
| ### 2.1 وضعیت فعلی HF | |
| #### ✅ نقاط قوت: | |
| 1. **کلاس پایه خوب** - `HuggingFaceService` با قابلیتهای زیر: | |
| - Rate Limiter (30 req/s) | |
| - Model availability cache | |
| - Retry logic با exponential backoff | |
| - Bearer token authentication | |
| 2. **سرویس اختصاصی Space** - `HFDataService` با: | |
| - Direct HTTP connection | |
| - Parallel data fetching | |
| - Complete error handling | |
| - Comprehensive response types | |
| #### ❌ نقاط ضعف: | |
| 1. **عدم وجود Unified Entry Point** | |
| ```typescript | |
| // ❌ مشکل فعلی: هر کامپوننت مستقیماً صدا میزند | |
| import { hfDataService } from '../services/HFDataService'; | |
| const data = await hfDataService.getMarketData(); | |
| // ❌ یا این: | |
| import { HuggingFaceService } from '../services/HuggingFaceService'; | |
| const hf = HuggingFaceService.getInstance(); | |
| const result = await hf.inference(...); | |
| // ❌ یا حتی این: | |
| const response = await fetch('https://api-inference.huggingface.co/...'); | |
| ``` | |
| 2. **Hard-coded URLs** | |
| ```typescript | |
| // در HuggingFaceService.ts خطوط 24-28 | |
| protected readonly INFERENCE_API_BASE = 'https://api-inference.huggingface.co/models'; | |
| protected readonly DATASETS_API_BASE = 'https://datasets-server.huggingface.co'; | |
| protected readonly HF_API_BASE = 'https://huggingface.co/api'; | |
| // در HFDataService.ts خطوط 19, 122 | |
| const HF_API_URL = process.env.HF_API_URL || 'https://...'; | |
| this.baseUrl = baseUrl || HF_API_URL; | |
| ``` | |
| 3. **پراکندگی توکنها** | |
| ```typescript | |
| // توکن در چندین مکان: | |
| process.env.HUGGINGFACE_API_KEY // env | |
| process.env.HF_TOKEN_B64 // base64 encoded | |
| process.env.HF_API_TOKEN // HFDataService | |
| apisConfig.huggingface?.key // ConfigManager | |
| ``` | |
| 4. **عدم هماهنگی در Error Handling** | |
| ```typescript | |
| // هر سرویس روش خودش را دارد: | |
| // HuggingFaceService: | |
| throw new Error(`Model ${modelId} not found or unavailable (404)`); | |
| // HFDataService: | |
| return { success: false, error: `HTTP ${response.status}`, ... }; | |
| // سایر فایلها: | |
| console.error('Failed to fetch'); | |
| logger.error(...); | |
| toast.error(...); | |
| ``` | |
| 5. **Inconsistent Caching** | |
| ```typescript | |
| // HuggingFaceService - Model Availability Cache (1 hour TTL) | |
| protected readonly modelAvailabilityCache = new Map<...>(); | |
| protected readonly MODEL_CACHE_TTL = 3600000; | |
| // RealDataManager - General Cache (2 minutes TTL) | |
| private cache: Map<string, { data: any; timestamp: number }>; | |
| private readonly CACHE_TTL = 120000; | |
| // هیچ استراتژی مشترکی وجود ندارد! | |
| ``` | |

| 9. سایر Providers | |
| 10. تستهای یکپارچگی | |
| ``` | |
| ### فاز 2: Migration تدریجی (هفته 2-3) | |
| #### 2.1 شناسایی فایلهای پرتکرار | |
| ```bash | |
| # Run analysis | |
| rg "fetch|axios" --type ts --type tsx -c | sort -rn | head -20 | |
| # خروجی نمونه: | |
| src/components/Dashboard.tsx: 45 | |
| src/views/TradingHub.tsx: 38 | |
| src/services/RealDataManager.ts: 32 | |
| ... | |
| ``` | |
| #### 2.2 استراتژی Migration | |
| **مرحله 1: Hookها** | |
| ```typescript | |
| // ❌ قبل | |
| useEffect(() => { | |
| fetch('https://api.binance.com/api/v3/ticker/price?symbol=BTCUSDT') | |
| .then(res => res.json()) | |
| .then(data => setPrice(data.price)); | |
| }, []); | |
| // ✅ بعد | |
| const { data: price } = useDataQuery({ | |
| source: 'binance', | |
| endpoint: '/api/v3/ticker/price', | |
| params: { symbol: 'BTCUSDT' } | |
| }, { | |
| cache: true, | |
| cacheTTL: 5000 // 5 seconds | |
| }); | |
| ``` | |
| **مرحله 2: سرویسها** | |
| ```typescript | |
| // ❌ قبل | |
| export class HFDataService { | |
| async getMarketData() { | |
| const response = await fetch(`${this.baseUrl}/api/market`); | |
| return response.json(); | |
| } | |
| } | |
| // ✅ بعد | |
| export class HFDataService { | |
| async getMarketData() { | |
| const response = await dataManager.fetch({ | |
| source: 'huggingface', | |
| endpoint: '/space/api/market', | |
| options: { cache: true, cacheTTL: 60000 } | |
| }); | |
| return response.data; | |
| } | |
| } | |
| ``` | |
| ### فاز 3: بهینهسازی و نظارت (هفته 4) | |
| #### 3.1 Dashboard نظارت | |
| ```typescript | |
| // src/views/admin/tabs/DataHighwayMonitor.tsx | |
| export const DataHighwayMonitor = () => { | |
| const stats = dataManager.getStats(); | |
| return ( | |
| <div> | |
| <h2>🛣️ Data Highway Monitor</h2> | |
| {/* Cache Statistics */} | |
| <CacheStats | |
| hits={stats.cache.hits} | |
| misses={stats.cache.misses} | |
| size={stats.cache.size} | |
| /> | |
| {/* Rate Limiter Status */} | |
| <RateLimiterStatus | |
| sources={stats.rateLimiter.sources} | |
| /> | |
| {/* Request Deduplication */} | |
| <DeduplicationStats | |
| saved={stats.deduplicator.duplicatesSaved} | |
| /> | |
| {/* Provider Health */} | |
| <ProviderHealth | |
| providers={['huggingface', 'binance', 'coingecko']} | |
| /> | |
| </div> | |
| ); | |
| }; | |
| ``` | |
| #### 3.2 Metrics & Logging | |
| ```typescript | |
| // Prometheus-style metrics | |
| export interface Metrics { | |
| http_requests_total: number; | |
| http_request_duration_seconds: Histogram; | |
| cache_hits_total: number; | |
| cache_misses_total: number; | |
| rate_limit_exceeded_total: number; | |
| provider_errors_total: Map<DataSource, number>; | |
| } | |
| ``` | |

| --- | |
| ## ⚠️ بخش 6: نکات مهم و هشدارها | |
| ### 6.1 Hugging Face Specific | |
| ```typescript | |
| // ⚠️ نکته 1: Model Loading Time | |
| // بعضی مدلها زمان loading میخواهند (503 error) | |
| // باید منتظر بمانیم و retry کنیم | |
| if (response.status === 503 && response.data.error.includes('loading')) { | |
| const estimatedTime = response.data.estimated_time || 10; | |
| await sleep(estimatedTime * 1000); | |
| // Retry | |
| } | |
| // ⚠️ نکته 2: Rate Limits | |
| // Free tier: 30 requests/second | |
| // با API Key: 1000 requests/second | |
| // ⚠️ نکته 3: Model Availability | |
| // همیشه ابتدا بررسی کنید model موجود است یا نه | |
| const isAvailable = await hfProvider.validateModelAvailability('model-id'); | |
| if (!isAvailable) { | |
| // Use fallback or show error | |
| } | |
| // ⚠️ نکته 4: Token Security | |
| // NEVER commit token directly | |
| // Use environment variables | |
| // Use base64 encoding for extra security | |
| // ❌ Bad | |
| const token = 'your_token_here'; | |
| // ✅ Good | |
| const token = process.env.HF_TOKEN_B64 | |
| ? Buffer.from(process.env.HF_TOKEN_B64, 'base64').toString('utf8') | |
| : process.env.HUGGINGFACE_API_KEY; | |
| ``` | |
| ### 6.2 Cache Strategy | |
| ```typescript | |
| // تعیین TTL بر اساس نوع داده | |
| const cacheTTL = { | |
| // Real-time data (5-30 seconds) | |
| prices: 5000, | |
| tickers: 10000, | |
| // Market data (1-5 minutes) | |
| marketData: 60000, | |
| ohlcv: 300000, | |
| // Static data (1 hour - 1 day) | |
| coinList: 3600000, | |
| modelInfo: 86400000, | |
| // News & Sentiment (5-15 minutes) | |
| news: 300000, | |
| sentiment: 600000, | |
| // AI Predictions (variable) | |
| aiSignals: 120000 // 2 minutes | |
| }; | |
| ``` | |
| ### 6.3 Error Handling Best Practices | |
| ```typescript | |
| try { | |
| const response = await dataManager.fetch({ | |
| source: 'huggingface', | |
| endpoint: '/space/api/market', | |
| options: { | |
| retry: true, | |
| maxRetries: 3, | |
| fallback: ['coingecko', 'binance'], // ✅ همیشه fallback داشته باشید | |
| timeout: 30000 | |
| } | |
| }); | |
| if (!response.success) { | |
| // Log error but don't crash | |
| logger.error('Failed to fetch market data', { error: response.error }); | |
| // Show user-friendly message | |
| toast.error('Unable to load market data. Using cached data.'); | |
| // Use cached or default data | |
| return getCachedData() || getDefaultData(); | |
| } | |
| return response.data; | |
| } catch (error) { | |
| // Fallback to emergency data source | |
| return await emergencyFallback(); | |
| } | |
| ``` | |

| ## 📊 بخش 7: مقایسه قبل و بعد | |
| ### 7.1 مثال کاربردی: Dashboard Component | |
| #### قبل (کد فعلی): | |
| ```typescript | |
| // ❌ Complexity: High, Maintainability: Low | |
| const EnhancedDashboardView = () => { | |
| const [marketData, setMarketData] = useState([]); | |
| const [priceData, setPriceData] = useState(null); | |
| const [newsData, setNewsData] = useState([]); | |
| const [loading, setLoading] = useState({ | |
| market: true, | |
| price: true, | |
| news: true | |
| }); | |
| const [errors, setErrors] = useState({}); | |
| useEffect(() => { | |
| // Fetch market data from HF | |
| setLoading(prev => ({ ...prev, market: true })); | |
| fetch('https://hf-space-url/api/market') | |
| .then(res => res.json()) | |
| .then(data => { | |
| setMarketData(data); | |
| setLoading(prev => ({ ...prev, market: false })); | |
| }) | |
| .catch(err => { | |
| setErrors(prev => ({ ...prev, market: err.message })); | |
| setLoading(prev => ({ ...prev, market: false })); | |
| }); | |
| // Fetch price from Binance | |
| setLoading(prev => ({ ...prev, price: true })); | |
| fetch('https://api.binance.com/api/v3/ticker/price?symbol=BTCUSDT') | |
| .then(res => res.json()) | |
| .then(data => { | |
| setPriceData(data); | |
| setLoading(prev => ({ ...prev, price: false })); | |
| }) | |
| .catch(err => { | |
| setErrors(prev => ({ ...prev, price: err.message })); | |
| setLoading(prev => ({ ...prev, price: false })); | |
| }); | |
| // Fetch news | |
| setLoading(prev => ({ ...prev, news: true })); | |
| fetch('https://hf-space-url/api/news') | |
| .then(res => res.json()) | |
| .then(data => { | |
| setNewsData(data); | |
| setLoading(prev => ({ ...prev, news: false })); | |
| }) | |
| .catch(err => { | |
| setErrors(prev => ({ ...prev, news: err.message })); | |
| setLoading(prev => ({ ...prev, news: false })); | |
| }); | |
| }, []); | |
| // ... 300+ lines of component code | |
| }; | |
| ``` | |
| #### بعد (معماری جدید): | |
| ```typescript | |
| // ✅ Complexity: Low, Maintainability: High | |
| const EnhancedDashboardView = () => { | |
| // تمام پیچیدگی در Data Highway است | |
| const { data: marketData, isLoading: marketLoading } = useDataQuery({ | |
| source: 'huggingface', | |
| endpoint: '/space/api/market' | |
| }, { | |
| cache: true, | |
| cacheTTL: 60000, | |
| fallback: ['coingecko'] | |
| }); | |
| const { data: priceData, isLoading: priceLoading } = useDataQuery({ | |
| source: 'binance', | |
| endpoint: '/api/v3/ticker/price', | |
| params: { symbol: 'BTCUSDT' } | |
| }, { | |
| cache: true, | |
| cacheTTL: 5000 | |
| }); | |
| const { data: newsData, isLoading: newsLoading } = useDataQuery({ | |
| source: 'huggingface', | |
| endpoint: '/space/api/news' | |
| }, { | |
| cache: true, | |
| cacheTTL: 300000 | |
| }); | |
| // تمام! فقط 20 خط به جای 300+ خط | |
| if (marketLoading || priceLoading || newsLoading) { | |
| return <LoadingState />; | |
| } | |
| return ( | |
| <div> | |
| <MarketSection data={marketData} /> | |
| <PriceSection data={priceData} /> | |
| <NewsSection data={newsData} /> | |
| </div> | |
| ); | |
| }; | |
| ``` | |
| ### 7.2 آمار مقایسهای | |

| ## 🎓 بخش 9: مستندات برای تیم | |
| ### 9.1 Quick Start Guide | |
| ```typescript | |
| // 1️⃣ Import the hook | |
| import { useDataQuery } from '@/data-highway/hooks/useDataQuery'; | |
| // 2️⃣ Use in component | |
| const MyComponent = () => { | |
| const { data, isLoading, error, refetch } = useDataQuery({ | |
| source: 'huggingface', | |
| endpoint: '/space/api/market', | |
| params: { limit: 100 } | |
| }, { | |
| cache: true, | |
| cacheTTL: 60000, | |
| fallback: ['coingecko', 'binance'] | |
| }); | |
| if (isLoading) return <Loading />; | |
| if (error) return <Error message={error} />; | |
| return <DataDisplay data={data} onRefresh={refetch} />; | |
| }; | |
| ``` | |
| ### 9.2 Available Data Sources | |
| ```typescript | |
| type DataSource = | |
| | 'huggingface' // 🤖 Hugging Face Space & Inference API | |
| | 'binance' // 🔷 Binance Exchange | |
| | 'coingecko' // 🟠 CoinGecko Market Data | |
| | 'news' // 🔴 News APIs (multiple sources) | |
| | 'sentiment' // 🟣 Sentiment Analysis | |
| | 'blockchain' // 🔵 Block Explorers (Etherscan, etc.) | |
| | 'backend'; // 🟢 Internal Backend API | |
| ``` | |
| ### 9.3 Common Patterns | |
| ```typescript | |
| // Pattern 1: Simple fetch with cache | |
| useDataQuery({ | |
| source: 'binance', | |
| endpoint: '/api/v3/ticker/price', | |
| params: { symbol: 'BTCUSDT' } | |
| }, { cache: true, cacheTTL: 5000 }); | |
| // Pattern 2: Auto-refresh data | |
| useDataQuery({ | |
| source: 'huggingface', | |
| endpoint: '/space/api/market' | |
| }, { | |
| refetchInterval: 30000 // Refresh every 30 seconds | |
| }); | |
| // Pattern 3: With fallback sources | |
| useDataQuery({ | |
| source: 'huggingface', | |
| endpoint: '/space/api/ohlcv', | |
| params: { symbol: 'BTC/USDT' } | |
| }, { | |
| fallback: ['binance', 'coingecko'] // Try these if HF fails | |
| }); | |
| // Pattern 4: Conditional fetching | |
| useDataQuery({ | |
| source: 'huggingface', | |
| endpoint: '/space/api/predictions', | |
| params: { model: selectedModel } | |
| }, { | |
| enabled: !!selectedModel // Only fetch if model is selected | |
| }); | |
| // Pattern 5: With callbacks | |
| useDataQuery({ | |
| source: 'news', | |
| endpoint: '/api/latest' | |
| }, { | |
| onSuccess: (data) => { | |
| console.log('News loaded:', data); | |
| trackEvent('news_loaded'); | |
| }, | |
| onError: (error) => { | |
| console.error('News failed:', error); | |
| showNotification('Failed to load news'); | |
| } | |
| }); | |
| ``` | |
| --- | |
| ## 🎉 نتیجهگیری | |
| ### خلاصه مشکلات فعلی: | |
| 1. ❌ **61 فایل** درخواست Hugging Face میکنند | |
| 2. ❌ **201 فایل** دارای `fetch/axios` هستند | |
| 3. ❌ هیچ **شاهراه مشخصی** برای عبور دادهها وجود ندارد | |
| 4. ❌ تکرار کد و ناهماهنگی بالا | |
| ### راهحل پیشنهادی: | |
| ✅ **Data Highway Architecture** با: | |
| - یک نقطه ورود (`DataManager`) | |
| - Provider pattern برای هر منبع داده | |
| - Custom React Hooks (`useDataQuery`) | |
| - Cache، Rate Limit، Error Handling یکپارچه | |
| - Monitoring و Metrics کامل | |
| ### بهبودهای مورد انتظار: | |
| - 📉 **-70%** کاهش خطوط کد | |
| - 📈 **+300%** بهبود Performance (با cache) | |
| - 📈 **+400%** بهبود Maintainability | |
| - 📈 **+500%** بهبود Developer Experience | |
| - ✅ **100%** کنترل بر Hugging Face requests | |
