2. Binance API Integration
Binance provides excellent APIs for both historical and real-time cryptocurrency data. Here's how to implement a robust data fetching system:
Historical Data Fetcher
// services/binanceAPI.js import axios from 'axios'; class BinanceAPI { constructor() { this.baseURL = 'https://api.binance.com/api/v3'; this.wsURL = 'wss://stream.binance.com:9443/ws'; } // Fetch historical kline data async getKlineData(symbol, interval, limit = 1000) { try { const response = await axios.get(`${this.baseURL}/klines`, { params: { symbol: symbol.toUpperCase(), interval: interval, limit: limit } }); return response.data.map(kline => ({ time: kline[0] / 1000, // Convert to seconds open: parseFloat(kline[1]), high: parseFloat(kline[2]), low: parseFloat(kline[3]), close: parseFloat(kline[4]), volume: parseFloat(kline[5]) })); } catch (error) { console.error('Error fetching kline data:', error); throw error; } } // Get current price async getCurrentPrice(symbol) { try { const response = await axios.get(`${this.baseURL}/ticker/price`, { params: { symbol: symbol.toUpperCase() } }); return parseFloat(response.data.price); } catch (error) { console.error('Error fetching current price:', error); throw error; } } // Get 24h price change statistics async get24hrStats(symbol) { try { const response = await axios.get(`${this.baseURL}/ticker/24hr`, { params: { symbol: symbol.toUpperCase() } }); return { priceChange: parseFloat(response.data.priceChange), priceChangePercent: parseFloat(response.data.priceChangePercent), volume: parseFloat(response.data.volume), high: parseFloat(response.data.highPrice), low: parseFloat(response.data.lowPrice) }; } catch (error) { console.error('Error fetching 24hr stats:', error); throw error; } } } export default new BinanceAPI();
Real-time WebSocket Connection
// hooks/useWebSocket.js import { useEffect, useRef, useState } from 'react'; import ReconnectingWebSocket from 'reconnecting-websocket'; export const useWebSocket = (symbol, interval, onMessage) => { const ws = useRef(null); const [connectionStatus, setConnectionStatus] = useState('Disconnected'); useEffect(() => { if (!symbol) return; const wsUrl = `wss://stream.binance.com:9443/ws/${symbol.toLowerCase()}@kline_${interval}`; ws.current = new ReconnectingWebSocket(wsUrl, [], { maxReconnectionDelay: 10000, minReconnectionDelay: 1000, reconnectionDelayGrowFactor: 1.3, connectionTimeout: 4000, maxRetries: Infinity, debug: false }); ws.current.onopen = () => { console.log('WebSocket Connected'); setConnectionStatus('Connected'); }; ws.current.onmessage = (event) => { try { const data = JSON.parse(event.data); if (data.k) { const kline = { time: data.k.t / 1000, open: parseFloat(data.k.o), high: parseFloat(data.k.h), low: parseFloat(data.k.l), close: parseFloat(data.k.c), volume: parseFloat(data.k.v), isFinal: data.k.x }; onMessage(kline); } } catch (error) { console.error('Error parsing WebSocket message:', error); } }; ws.current.onclose = () => { console.log('WebSocket Disconnected'); setConnectionStatus('Disconnected'); }; ws.current.onerror = (error) => { console.error('WebSocket Error:', error); setConnectionStatus('Error'); }; return () => { if (ws.current) { ws.current.close(); } }; }, [symbol, interval, onMessage]); return { connectionStatus }; };
3. TradingView Chart Implementation
Now let's implement the core charting component using TradingView Lightweight Charts with professional styling and features:
