StreamPriceX: Real-time Crypto Price Tracking

StreamPriceX is a real-time cryptocurrency price tracking platform that I built to provide live market data and historical analysis. The platform streams live prices from multiple exchanges and stores them in TimescaleDB for fast querying and analysis.

🎯 Project Overview

StreamPriceX provides:

  • Real-time Price Streaming: Live price updates via WebSocket
  • Historical Data Analysis: Time-series data storage and querying
  • CSV Export: Data export for external analysis
  • Multiple Cryptocurrencies: Support for top 100+ cryptocurrencies
  • Performance Analytics: Price movement and volatility analysis

🏗️ Technical Architecture

Core Components

  • Node.js Backend: Express server with WebSocket support
  • TimescaleDB: Time-series database for price data
  • CoinMarketCap API: Real-time price data source
  • WebSocket: Real-time client communication
  • CSV Export: Data export functionality
