Enhance Cryptocurrency Details Service with Improved Error Handling and Caching

Description

Summary of Work

This pull request introduces improvements to the cryptocurrency details service, focusing on:

1. Robust error handling for coin detail retrieval
2. Implementing a caching mechanism using node-cache
3. Providing a structured approach to managing mock cryptocurrency data

Key Improvements:

• Added input validation for coin IDs
• Implemented a 10-minute cache for coin details
• Created a comprehensive error handling middleware
• Structured mock data for easy extension

Future Considerations:

• Replace mock data with real-time cryptocurrency API integration
• Add more comprehensive test coverage
• Implement more advanced caching strategies

Changes Made

• Added input validation function validateCoinId()
• Implemented error handling middleware coinDetailsErrorHandler()
• Created a 10-minute cache using node-cache
• Structured mock coin data with consistent properties
• Added normalization of coin IDs to lowercase
• Implemented caching logic in getCoinDetails() function

Tests and Verification

• Manual testing of coin details retrieval
• Verified error handling for:
  • Missing coin ID
  • Non-existent coin ID
• Confirmed caching mechanism works as expected
• Validated input validation logic
