Cryptocurrency Dashboard

A real-time cryptocurrency dashboard built on Val Town that displays market data for the top cryptocurrencies.

Features

Real-time Data: Displays current prices, market caps, and 24-hour changes for top cryptocurrencies
Detailed Information: Click on any cryptocurrency to view detailed information including price charts and descriptions
Search Functionality: Filter cryptocurrencies by name or symbol
Auto-refresh: Data automatically refreshes every 60 seconds
Responsive Design: Works on desktop and mobile devices

Implementation Details

This project uses:

CoinGecko API: For fetching cryptocurrency market data
Tailwind CSS: For styling the UI
Chart.js: For rendering price charts
Font Awesome: For icons

API Endpoints

The application provides the following API endpoints:

GET /api/crypto: Returns a list of top cryptocurrencies (default: 50)
- Query parameters:
  - limit: Number of cryptocurrencies to return (e.g., /api/crypto?limit=10)
GET /api/crypto/:id: Returns detailed information about a specific cryptocurrency
- Example: /api/crypto/bitcoin
GET /api/btc: Returns Bitcoin data (for backward compatibility)

Fallback Mechanism

The application includes mock data that is used as a fallback when the CoinGecko API is unavailable or rate-limited. This ensures that the dashboard remains functional even when external services are down.

Future Improvements

Potential enhancements for this project:

Add historical price data for more accurate charts
Implement portfolio tracking functionality
Add price alerts
Include more detailed technical indicators
Support for additional currencies (EUR, JPY, etc.)
